Huayu for engineering students

Chapter 227

"You miss me, every day." At the entrance of the airport, Wang Fei hugged Wang Xu tightly, not wanting to part for a moment, and there seemed to be tears in her eyes.

"Well, yes, you also miss me. Be careful when filming, someone harassed and told me." Wang Xu comforted softly.

"You have said it many times, you will be careful." Wang Fei rubbed her head against Wang Xu's chest, took a long breath, and continued, "Remember your smell, and you should remember mine too."

"Well, yes." Wang Xu rubbed Wang Fei's hair, which was still smooth and supple.

"Let's go." Wang Fei let go of her hand, stood on tiptoe, kissed Wang Xu's lips lightly, turned around and left, walking firmly, no longer like a little girl just now.

Wang Xu watched as Wang Fei and Sister Ying walked into the terminal building, turned back to the side of the road, put on their helmets, and left on a motorcycle.

The management of the airport is not so strict at the moment. Although some people will say that the airport stops for a while, it will not be towed away immediately.

Speeding all the way, Wang Xu bid farewell to Wang Fei and returned to his busy daily life.

Although school hadn't started yet, for convenience, Wang Xu returned to live in the school. Living here is not so convenient, and the doctor's dormitory has not yet been allocated.

There is no special spring class in Shuimu now, Wang Xu's graduation is not a proper one, and all procedures have to be handled separately.

Fortunately, the department didn't let Wang Xu run by himself, and everything was arranged by the department. Anyway, Wang Xu became the only doctoral student in the spring class, which can be regarded as the first of its kind.

In fact, Wang Xu now exists more as a question-answering machine, but he also has his own focus, which is the verification of the growth method.

In his eyes, the fundamental method of the growth method is the foundation of all follow-ups. Only by verifying it first can everything follow-up become logical.

The experiment of the growth method was carried out in the Department of Materials, but a professor from the Department of Chemistry participated. There is no such vapor deposition equipment now, but the design drawings given by Wang Xu are very detailed.

Especially the laboratory equipment itself is not complicated, and the processing is not difficult. Mizuki's school-run factory can handle it.

Don't underestimate Mizuki's school-run factory. This small factory was very brilliant in the past, and many famous Chinese equipment were made here as verification models.

Although it is very desolate now, there are still many senior technicians above level [-] remaining. These people are Mizuki's confidence and confidence in being able to process many experimental devices.

Of course, the equipment this time is no exception. The main principle of the equipment is to maintain the combination of vacuum and high temperature, so there are certain requirements for processing accuracy, but it is not outrageous. Therefore, under overtime, within a week, a vacuum vapor deposition equipment for the laboratory was manufactured.

Although it is laboratory equipment, the total weight of the equipment exceeds several tons, so the final assembly of the equipment is carried out in the laboratory that was vacated earlier.The assembler is of course Wang Xu, who knows this thing best, and his skills are even more impressive.

In fact, Wang Xu himself didn't expect that this vapor deposition device had caused a sensation in the Department of Materials and Mechanics before the experiment started.

The root cause of everything is not the deposition equipment itself, but the vacuum pump that draws the vacuum.Since the current domestic vacuum pump cannot meet the various parameter requirements of the vacuum chamber, Wang Xu had no choice but to draw a new type by himself.

Even with the best CAD software available today, Wang Xu still stayed up all night to draw for two days before he finished the drawing of the pump. Fortunately, it was copied.

Damn software, it's not smooth, could it be... Forget it, let's do it one by one.

This thing comes from his maintenance skills. Vacuum pumps and booster pumps are actually one kind of thing. Although the things provided by the system are not more advanced than the products of the 21st century, they are better than what Huaxia has now.

Moreover, because Wang Xu copied the blueprint, he also copied the gears in the vacuum pump and the refining method of the steel required. Regardless of whether it is shocking or not, anyway, single crystal copper has come out, so it is not surprising that there are more steels, right?

However, there is only a general method for this refining method, so several old professors from the Materials Department studied for a few days, and finally succeeded in refining a new type of corrosion-resistant steel in the metallurgical laboratory.

The Department of Materials had a metallurgical laboratory in the early years, but in the early days of the founding of the People’s Republic of China, when the departments were adjusted, professors, personnel and most of the equipment were supported, and the predecessor of the later Imperial University of Science and Technology, the Iron and Steel Industry College, was established.

Of course, the Steel Institute not only accepts Mizuki's metal majors, but also some metal majors from other universities.Therefore, the Steel Institute has become a leader in Huaxia's metal industry, especially in the field of steelmaking.

However, the Mizuki Materials Department only left a laboratory for non-metal materials and a small amount of metal materials laboratories, so that Wang Xu had to go to the school-run factory if he wanted to find a metallurgical laboratory.

However, Mizuki also slowly rebuilt the metal laboratory and metallurgy and other majors, mainly engaged in frontier research such as powder metallurgy, and seldom involved in steelmaking and the like.

At that time, the major adjustment of departments involved almost all the established universities in China. You can see the shadow of Mizuki in many prestigious universities.

The main body of the University of Geosciences was the Geology Department of Imperial University, which was merged with the geology departments of other universities, and even some teachers from the Electronics Department of Mizuki were merged into it, which became the later Electronics Major of Imperial University.

Anyway, at that time, almost all the eight colleges on Imperial College Road were established in this way. Later, when many universities in China were established, they would draw support from these old famous schools. This was a very common phenomenon in that era.

However, in this life, since Wang Xu developed single-crystal copper, the call for rebuilding metal majors, and even metallurgy majors, was raised. Metallurgy is not without cutting-edge topics.

For example, powder metallurgy is a part of Wang Xu's project this time, because his speakers urgently need the support of strong magnets.

Anyway, the material department has already been messed up by him, so it wouldn't hurt to be a little more messy.

This time, for steelmaking, Mizuki really didn't have any equipment.But that’s not a problem. Shuimu doesn’t have one, but the Steel Academy that was aided back then does, and it’s only a few bus stops away from Shuimu.

Therefore, even after decades have passed, there are really many connections between the two schools.I handed over the ideas given by Wang Xu to a friendly old professor and asked him to arrange experiments, so the Department of Materials could do other things with peace of mind.

As a result, at the Steel Academy, a student of the old professor took over the project, and then using the ideas given by Wang Xu, he quickly produced this corrosion-resistant steel, and after a series of heat treatment processes in the description.

The disciple was surprised to find that the various parameters of this thing are ridiculously good, not to mention wear-resistant and corrosion-resistant, and it also has excellent tensile yield strength, which is considered top-notch among alloy steels. Isn't this an excellent ship steel.

Then, as it should be, the metallurgical profession over there exploded, and many people came to watch this important achievement, and various tests were carried out quickly.

You should know that although the Academy of Steel is not a national defense academy, since metallurgy is a heavy industry, and almost all equipment in the military is inseparable from the improvement of the performance of metallurgical materials.So, there have always been representatives of the permanent army here, um, so ha, soon, people in white uniforms also came.

Then various sampling, strength test, wear test, performance test, acid-base test, salt resistance test, high and low temperature test were carried out in laboratories of different institutions.

Repeated experiments are of course inevitable, and have been carried out in the Steel Academy more than once.

Then, those in green uniforms and blue uniforms came, and the above description unfolded again.

Don't think they are wasteful. It is irresponsible not to test the results in your own laboratory. A sample is tested in multiple laboratories and referred to each other, which is the prerequisite for the final determination of material properties.

Anyway, in this steel academy that just finished the new year and is still full of festive atmosphere, I don't know how many people are too busy to go home.

Not to mention the gossip in the steel institute, the materials department was also a little dumbfounded when they got the results and finished products.

But still immediately used this batch of steel to process and produce the required vacuum pump, because the teacher of the mechanical department is still waiting.

Therefore, when the vacuum pump that only existed on the blueprint was actually manufactured, a professor of the mechanical department stared at the finished product for a long time.

This is a small pump about the size of a hand-held radio, compact and delicate.

Since it has just been manufactured and the shell has not been painted yet, it looks shiny, and it really looks good, with a unique industrial beauty.

But obviously, that's not what the mechanical department professor saw. He's seen too much industrial beauty, so it's not bad for this one.

Mainly, he thought, if this thing is slightly modified, the air inlet and outlet are reversed, and a tank is added on the other side. If the refrigerant is not sent in instead of air, isn't this a compressor?

You must know that the structure of the compressor is not complicated, but the complexity lies in the material and processing.It is not that there are no compressors in China, but the compressors produced are large, noisy and short in life.

But the thing in front of me is small and compact enough, and the material he uses is highly corrosion-resistant and wear-resistant, so it can be... .

Do you know how many refrigerators and air-conditioning compressors Huaxia imports every year? Do you know how many imported refrigerator and air-conditioning production lines shut down because there is no foreign exchange and cannot import compressors?

The teacher of the mechanical department seemed to have a feeling that a large piece of gold fell on his head, and he was a little staring. He felt that it might not be just him, but many people would not be able to sleep because of it.
