Chapter 184 Coating

She needs a coating with a high melting point, the ability to withstand high temperatures for a long time, the ability to withstand high-temperature erosion of up to 3500°C at the nozzle, a low thermal expansion coefficient, low high-temperature volatility, and excellent ductility, fatigue resistance, and oxidation resistance.

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

According to her needs, brief or detailed information about 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 screened out interference and left useful directions.

Ideas kept flashing through her mind. The absolute direction guided her forward and the deduction brought endless possibilities. Under her pen, a series of derivation formulas extended out. Finally, a directional compound molecular formula condensed at the tip of Wu Tong's pen. Inorganic material, that was it, and the preparation process gushed out simultaneously.

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

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

With such a great learning opportunity and such an advanced research direction, if they have any questions, they can ask Wu Shen for advice. Wu Shen can basically give them immediate solutions and give them the finishing touch. Their gains, progress, and growth can be described as rapid.

Therefore, several people encouraged each other and decided to work hard as long as their livers were not dead. He thought that how great their future achievements would be would depend on their hard work at this moment.

"Mr. Wu!" Several people who were doing in-depth research on polygonal silicon oxide noticed Wu Tong's entry and called out in surprise.

"Tao Ran? Zhang Qi... You guys didn't go back either?" Wu Tong came back to her senses from the perfecting of the preparation process and was a little surprised. She remembered that they were among those who could go home.

"Hehe... Mr. Wu, Happy New Year. You haven't gone home yet. I happened to ask you for advice before, and the guidance we got gave us some new ideas about polygonal silicon oxide. We would like to discuss and research more!" Several people smiled, Tao Ran touched his head, greeted Wu Tong in the first place, and explained.

"Are you here to get the N18 experiment report? N18 is amazing, and is definitely a major achievement that is no less than the bidirectional high-energy material N24. Its solution has a particularly strong decomposition ability and can actually promote the decomposition of a large amount of organic matter, even chemical fibers, plastics... these white garbage that seriously pollute the environment can be decomposed. By adjusting the ultraviolet band, it can produce carbon monoxide, methane, ethane and other alkane substances that are useful to humans. There is a way to save our domestic garbage pollution!"

Tao Ran quickly handed the experimental report they had prepared to Wu Tong, and looked at Wu Tong excitedly and admired him. Mr. Wu was really amazing. He could actually develop such an amazing thing. You know, China has a population of 1.3 billion, accounting for one-fifth of the world's total population. The garbage produced every day is about 1.5 million tons. If excrement is added, the number will be even more terrifying.

Now, with N18, one gram can decompose about eight kilograms of various garbage and convert them into gas reserve materials. It is equivalent to that they have an inexhaustible natural gas vein, and its value is incredibly high!

China is short of crude oil and natural gas resources. In terms of natural gas, many places rely on imports and try not to use as much of the country's mineral resources as possible. If there is such a powerful supplement, it will definitely be a national strategic resource, which can save the country a lot of foreign exchange and feed back to the national economy. Its value is immeasurable.

"This is a very good experimental report. Thank you for your hard work. You still need to organize all the data and I will contact you to report it." Wu Tong quickly glanced at the report in her hand and praised it. This was a report that met her expectations.

However, this was the known result of her deduction and prediction, and was not her focus today.

"It just so happens that you're all here today. Have you all eaten? If you're sorry, please help me with another experiment!"

"Okay, no problem, Wu Shen, just give me your orders. We have all eaten. Today is 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 tonight. Wu Shen, let's celebrate the New Year together then!" Tao Ran excitedly invited on behalf of his brothers.

"Then we have to speed up and finish the experiment as soon as possible so that we can have the New Year's Eve dinner!" Before Wu Tong came over, he just casually filled his stomach with the instant food stored in the office. Now 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 the high temperature..." With help, Wu Tong didn't have to prepare it himself, and the process was much faster.

As the sun sets and night slowly covers the earth, everyone in the laboratory stares at the temperature data that keeps rising in the test room: one thousand degrees, two thousand degrees, three thousand degrees, four thousand degrees...

Excited cheers rose up, "My God, we succeeded, we succeeded again!"

Wu Tong looked at the coating solution prepared in front of him and the coated metal sheet used in the experiment, which changed only at a high temperature of over 4,000 degrees, and his expression was very happy.

Inspiration came smoothly. She used high-temperature treated yttrium trioxide, dysprosium trioxide, SrZrO3, SiC, ZrB2 and other pure inorganic materials with melting points above 3000℃. They are resistant to oxidation and non-volatile at high temperatures. They take advantage of the fusion effect with the co-bond effect. Under the action of high temperature, the dense coating material obtained after lattice transformation has low oxygen permeability, better inhibition of oxygen diffusion and good ductility.

During the high-temperature and high-pressure solid-phase sintering process, a large amount of complex carbon molecules will be dissolved 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. The coating exhibits good plasticity and adhesion, good film-forming properties, and high temperature resistance.

Wu Tong also added a certain amount of rare earth oxides that had been treated at high temperatures, so that under high temperatures and under a synergistic effect, the coating had 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 effect and synergistic effect of various materials are prominent, and the mechanical properties are good. The coating can also maintain certain mechanical properties at 4000℃.

High temperature resistance, no volatility, good ductility, high film-forming properties, curable in synthesis, can work for a long time in a high temperature environment below 4000℃, no aging, good adhesion... This is the coating material that perfectly meets her expectations!

Wu Tong's eyes were filled with joy. Success came one after another. In just two days, she finished the things she expected to be busy with before and after the New Year. The research went so smoothly, which made her the happiest.

Sure enough, people really need enough motivation. When they are motivated enough, everything is possible.
