She needed 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, and high thermal vibration resistance. The material 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. She compared and referenced the existing material library discovered in nature. Wu Tong constantly filtered out interference and left useful directions.
Ideas kept flashing through her mind. The absolute direction guided her forward, and the deduction brought infinite possibilities. Under her pen, a series of deduction formulas extended. 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 doubts, 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 high their future achievements would be would depend on their fighting spirit at this moment.
"Mr. Wu!" Several people who were conducting in-depth research on polygonal silicon oxide noticed Wu Tong's entry and called out in surprise.
"Tao Ran? Zhang Qi...you haven't gone back yet?" Wu Tong came back to her senses from the perfecting of the preparation process, 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 just asked you for advice before. The guidance we got gave us some new ideas about polygonal silica. We would like to discuss and study it more!" Several people chuckled. Tao Ran touched his head, greeted Wu Tong in the beginning, and explained.
"Are you here to get the N18 lab report? N18 is incredible, a major achievement on par with the bidirectional high-energy material N24. Its solution possesses exceptionally strong decomposition capabilities, capable of promoting the breakdown of large amounts of organic matter, even chemical fibers, plastics... these white wastes that severely pollute the environment. By adjusting the ultraviolet wavelength, it can produce carbon monoxide, methane, ethane, and other alkanes that are beneficial to humans. Our domestic waste pollution is about to be solved!"
Tao Ran quickly handed Wu Tong the lab report they had prepared, and looked at him excitedly with admiration. "Mr. Wu is truly amazing. He was able to develop something so amazing." You have to understand. China has a population of 1.3 billion, accounting for one-fifth of the world's total population. They produce approximately 1.5 million tons of garbage every day. If you add in excrement, the number would be even more terrifying.
Now, with N18, one gram can decompose about eight kilograms of various garbage and convert them into gas reserves. It is equivalent to giving them an inexhaustible source of natural gas, the value of which 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 also feed back to the national economy. Its value is immeasurable.
"It's 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? I'd be sorry if you could 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 tonight will be even richer. 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 darkness slowly covers the earth, everyone in the laboratory stares at the ever-increasing temperature data 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 to her, and 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, and they take advantage of the fusion by the co-bonding 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, 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 synergistic effects, the coating had the ability to self-heal and resynthesize.
After the coating is completely cured, it 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 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. She finished the things she expected to be busy with before and after the New Year in two days. The research was so smooth and silky smooth, which made her most happy.
As expected, people really need enough motivation. When they have enough motivation, everything is possible.
