Chapter 187 What do you mean...

Listening to everyone's discussions and proposed solutions, Ning Chen was constantly thinking about something.

Although Ning Chen's experience in steel smelting is far less than that of other members of the project team, as the designer of this material, Ning Chen's understanding of this material is definitely higher than anyone else.

In addition, Ning Chen has very strong thinking ability and very comprehensive professional knowledge. Ning Chen does not feel that he will definitely not be able to come up with valuable solutions.

Ning Chen turned his brain to its highest state, thinking about various solutions to the hydrogen embrittlement problem.

"Wait a minute... the main cause of hydrogen embrittlement is the cadmium plating process. So if we directly cancel the cadmium plating process, can we avoid the occurrence of hydrogen embrittlement?"

Ning Chen’s idea can be said to have a very strange angle, because steel used in the aerospace and aviation fields in the past required protective, cyanide-based cadmium plating.

It is precisely because of the cadmium plating process that subsequent hydrogen reduction annealing is required to avoid hydrogen embrittlement.

However, this annealing process cannot completely solve the problem of hydrogen embrittlement, and the annealing conditions are very strict, and a little carelessness may affect the degree of hydrogen removal.

Following this line of thinking, Ning Chen continued to think forward and really sorted out a complete idea.

Because the system provides more than just one kind of steel material, Ning Chen is very flexible in selecting and improving the steel material design plan that meets his own requirements from these data.

Seeing that no one proposed any good solutions, Cheng Zhong decided to put this issue aside for the time being and continue discussing other issues.

But at this moment, Ning Chen raised his hand and said:

"Academician Cheng, I have a solution to the hydrogen embrittlement problem."

Hearing Ning Chen's words, the project leaders and members, including Cheng Zhong and Tian Shihao, were a little surprised.

Although Ning Chen has shown very strong talent and ability in material design, when it comes to steel material processing technology, Ning Chen is a complete newcomer and has learned many things from scratch.

It's like a scholar who is familiar with military books and suddenly wants to lead troops to fight. It is difficult for people to feel trustworthy.

Cheng Zhong didn't believe that Ning Chen could come up with any good process plan, but Cheng Zhong still nodded and said:

"Ning Chen, you can put forward any ideas you have, and we will discuss the specific feasibility together."

After getting Cheng Zhong's permission, Ning Chen said:

"I think we can completely avoid hydrogen embrittlement by using the cadmium plating process."

After hearing Ning Chen's words, everyone's expressions suddenly froze.

Because according to everyone's conventional thinking, the cadmium plating process is a processing technology that must be experienced for steel materials used in aerospace, aviation and other fields.

Only after being processed by the cadmium plating process, the steel material will have corrosion resistance.

Otherwise, steel materials will not be able to adapt to complex environments, will be easily corroded, and their service life will be greatly reduced.

"Ning Chen, if there is no cadmium plating process, how can we ensure the corrosion resistance of steel materials?" A member of the project team couldn't help but ask.

Others also had the same questions in their minds, and some were curious about what Ning Chen was thinking.

Ning Chen was well prepared for these questions and answered calmly:

"Yes, under normal circumstances, if you want to make steel materials highly resistant to corrosion, you do need to use the cadmium plating process. But I think other methods can still achieve similar effects. Even, this method Compared with the cadmium plating process, steel materials can have better corrosion resistance."

After hearing Ning Chen's words, Cheng Zhong said eagerly:

"Ning Chen, please tell me your method!"

"Academician Cheng, this method may not be explained clearly in a few words. Can I use the whiteboard?"

"Of course it's no problem, just use it."

After getting Cheng Zhong's consent, Ning Chen picked up a whiteboard pen and drew his newly improved design on the whiteboard.

At the beginning, everyone could not quickly understand what Ning Chen was thinking.

However, as the design plan on the whiteboard gradually became clear, Tian Shihao first understood Ning Chen's thoughts.

"Ning Chen, you mean that steel materials can be passivated?"

"Yes, this is indeed one of the ways to improve the corrosion resistance of steel materials. Moreover, our improved material is very suitable for passivation treatment. After passivation treatment, a very stable layer can be formed on the surface. Passive oxide film..."

After having enough experience in materials science, Ning Chen will not mechanically adhere to various conventional methods, but will actively try to innovate.

Of course, Ning Chen's innovations are also very well-founded. While maintaining innovation, he uses a rigorous knowledge theory system to support his own opinions.

Looking at the design plan that Ning Chen made on the whiteboard and listening to Ning Chen's explanation, everyone knew that Ning Chen was not just talking about it on paper, but that there really was something in it.

At this time, a member of the project team raised his hand and asked:

“This kind of steel material is indeed very suitable for passivation treatment. Passivation treatment can indeed greatly enhance the corrosion resistance of steel materials. But just a passivation treatment can really improve its corrosion resistance. , can it reach the level of other steel materials that have undergone cadmium plating?”

"Don't worry, passivation treatment is not the only process to improve the corrosion resistance of materials. Before this, we will also heat treat the steel materials and add a small amount of chromium..."

After listening to Ning Chen's further explanation, Cheng Zhong couldn't help but said excitedly:

"Yes, after these series of processes, theoretically the steel material will indeed have very strong corrosion resistance. This not only completely avoids the occurrence of hydrogen embrittlement, but even makes the material more resistant to corrosion than before! "

To be able to make an academician-level figure like Cheng Zhong so excited that he could express his emotions was enough to show how outstanding the plan Ning Chen was involved in was.

"Yes, Academician Cheng, I also think Ning Chen's plan has great research value. If these process procedures can be perfectly demonstrated in experiments, it is really possible for us to produce a new generation of aerospace, Aviation steel materials!”

With the support of Cheng Zhong and Tian Shihao, others also felt that Ning Chen's plan was very good and did not raise any objections to it.

In the following time, everyone continued to discuss some details of this plan and formulated a more specific experimental plan.

At this time, Ning Chen did not express his own opinions too much, but listened carefully to the discussions of the experts.

The plans proposed by Ning Chen were more about process design at a macro level. As for some process details, Ning Chen knew that other experts were better at them.

However, Ning Chen would not be satisfied with his current ability level. He listened very carefully to every word of the experts so that he could learn more about the details of the process.

After several days of countless discussions, everyone formulated a specific plan for the experiment and began to try to prepare Ning Chen's improved steel material.

Although steelmaking in the laboratory does not seem to be as troublesome as steelmaking in a steel factory, in actual operation, no important steps are ignored, but mass production is not required.

After a stage of experiments, the project team successfully synthesized some experimental samples and prepared to conduct detailed tests on this steel material.

During this period, Ning Chen gradually became familiar with many details of the process, and his understanding of steel smelting and various processing procedures was much improved than before.

Ning Chen followed the experts and started testing this steel material.

After some preliminary testing, it can be found that the steel materials processed by the project team are generally highly similar to Ning Chen's ideal design structure.

However, Ning Chen was also able to discover the differences from some details.

From the perspective of microstructural characteristics, the materials processed by the project team did not meet the optimal microstructural characteristics requirements designed by Ning Chen.

The distribution of fine grains and extremely fine metal carbides is also far from Ning Chen’s ideal situation.
