Before returning to the college entrance examination, I became popular in the science circle

She needs a coating that has a high thermal melting point, can withstand high temperatures for a long time, can withstand the high temperature erosion of the nozzle up to 3500°C, has a low thermal expansion coefficient, less high temperature volatilization, and has excellent ductility, fatigue resistance, and oxidation resistance. .

It must have high thermal conductivity, good heat transfer, good ductility, and high thermal shock resistance coefficient...the texture should not be too thick or too thin.Too thick will affect the combustion chamber parameters, and too thin will have little effect.

According to her needs, brief or detailed information on various existing high-temperature coatings emerged from her mind. She pulled it out again and stored it in her memory. For comparison and reference, Wu Tong constantly sifted away distractions, leaving useful directions behind.

Continuous thoughts flashed through her mind, the absolute direction guided her forward, and the deduction brought infinite possibilities. In her hand, a series of derivation formulas spread out, and finally a directional compound molecular formula condensed at the end of Wu Tong's pen. Inorganic materials, this is it, and the preparation process is simultaneously sprayed out.

After orientation, with all the manuscripts in her mind, Wu Tong went straight to the laboratory.

In the chemical compound laboratory, Tao Ran and others who followed Wu Tong to prepare N24 also chose not to go home this year. Even I didn't go home, so what qualifications did they have to run away?

Such a good learning opportunity, such an advanced research direction, if you have any doubts, you can ask me for advice. My god can basically give you immediate solutions and give them the finishing touch. Their gains, progress, and growth are simply applicable. To describe it as fast.

Therefore, several people cheered together, and as long as the liver was not dead, they would work hard. How high their achievements in the future would be, he thought, would depend on their hard work at this time.

"Mr. Wu!" Several people who were doing in-depth research on polygonal silicon oxide immediately noticed Wu Tong's entry and called out without surprise.

"Tao Ran? Zhang Qi... you haven't gone back either?" Wu Tong came back from perfecting the preparation process and was a little surprised.She remembered that they were the ones who could go home.

"Hehe... Mr. Wu, happy New Year, you haven't gone back yet. I just asked you for advice before, and the advice we got gave us some new ideas about polygonal silicon oxide. We want to discuss and study it more!" Several people With a smile, Tao Ran touched his head, greeted Wu Tong and explained.

"Are you here to get the experimental report of N18? N18 is so awesome. It is definitely as important as the two-way high-energy material N24. Its solution has a particularly strong decomposition ability and can actually promote the decomposition of a large number of organic matter, even chemical fibers and plastics. ···These white wastes that seriously pollute the environment can be decomposed. By adjusting the ultraviolet band, carbon monoxide and alkanes such as methane and ethane can be produced in a targeted manner. Our domestic waste pollution will be saved! "

Tao Ran quickly handed the experimental report they prepared to Wu Tong, and looked at Wu Tong with excitement and admiration. Mr. Wu was so awesome that he could develop such an awesome thing.To know.China has a population of 13 billion, accounting for one-fifth of the world's total population. It produces about 150 million tons of garbage every day. If excrement is added, the figure is even more terrifying.

But now, with N18, one gram can decompose about eight kilograms of various garbage and convert it into gas preparation materials. This is equivalent to giving them an inexhaustible natural gas vein with a value of Incredibly high!

China is poor in crude oil and natural gas resources. In terms of natural gas, many places rely on imports and try not to use as much national mineral resources. If there is such a powerful supplement, it will definitely be a national strategic resource and save the country countless amounts. Foreign exchange can also feed back the national economy and is of immeasurable value.

"It's a very good experimental report. You have worked hard. All the data needs to be sorted out by you. I will contact you and report it." Wu Tong quickly glanced at the report in his hand and praised that this was a report that met her expectations.However, this was her prediction of a known result, and it was not her focus today.

"You happen to be here today, have you all eaten? If you're going to be hard-working, please help me do an experiment together!"

"Okay, no problem, my God, just ask. We have all eaten. Today is the Chinese New Year, and the cafeteria has prepared a rich meal. It is said that the New Year's Eve dinner will be even richer in the evening. My God, let's celebrate the New Year together then!" Tao Ran said excitedly Invitation on behalf of the brothers.

"Then we have to speed up, complete the experiment as soon as possible, and go have the New Year's Eve dinner!" Before Wu Tong came over, he just used the convenient food stored in the office to make a cushion. At this moment, he was also looking forward to the New Year's Eve dinner in the cafeteria in the evening.

"Tao Ran, prepare yttrium trioxide, dysprosium trioxide, SrZrO3, SiC, ZrB2... these pure inorganic materials, Zhang Qi, preheat to high temperature...!" With a helper, Wu Tong does not need to prepare by himself, the process It's much faster.

As the sun sets and night slowly covers the earth, everyone in the laboratory is staring at the rising temperature data in the testing room, one thousand degrees, two thousand degrees, three thousand degrees, four thousand degrees...
Excited cheers arose, "My God, we succeeded, we succeeded again!"

Wu Tong looked very happy when he looked at the coating solution prepared in front of him and the coated metal pieces used for experiments, which only change at temperatures above four thousand degrees.

The inspiration went smoothly. She used high-temperature treated inorganic materials such as yttrium trioxide, dysprosium trioxide, SrZrO3, SiC, and ZrB2, all of which have melting points above 3000°C. They are pure inorganic materials that are resistant to oxidation and non-volatile at high temperatures. They are intercepted by co-bonding effects. The advantages of fusion are that under high temperature, the dense coating material obtained after lattice conversion has low oxygen permeability, has a better inhibitory effect on the diffusion of oxygen, and has good ductility.

During the high-temperature and high-pressure solid-state sintering process, a large amount of solid solution of complex carbon molecules and the reverse solid solution of the carbon crystal phase transformation process will occur, forming a melt growth composite effect, which has a good ability to form a continuous three-dimensional network crystal structure, and the coating reflects Good plasticity and adhesion, good film-forming properties, and high temperature resistance.

Wu Tong also added a certain amount of rare earth oxides that have been treated at high temperatures, so that under high temperatures and under a synergistic effect, the coating has the ability to self-heal and resynthesize.

After the coating is completely cured, the coating has the characteristics of high melting point, high hardness, high chemical stability, corrosion resistance and impact resistance. Moreover, at high temperatures, the additive and synergistic effects of various materials are highlighted, and the mechanical properties are good. The layer is a material that can maintain certain mechanical properties even at 4000°C.

High temperature resistance, non-volatile, good ductility, high film-forming properties, has the ability to cure in synthesis, can work in high temperature environments below 4000°C for a long time, does not age, and has good adhesion... This is a coating that perfectly meets her expectations. layer of material!

Wu Tong's eyebrows were filled with joy. Successes came one after another. Within two days, she completed the things she expected to be busy with before and after the New Year. The research was so smooth and smooth, which was the most joyful and happy thing.

Sure enough, people really need to be motivated enough. When there is enough motivation, everything is possible.
