Chapter 117 When something good happens, I think of my father-in-law

"Liao Ke, no red rust appears in the 960-hour salt spray test. This is the standard I set according to relatively conservative requirements."

"In fact, if the Dacromet surface treatment is carried out strictly according to the process, there will be no problem in not having red rust after 1200 hours of salt spray test."

Jiang Hui looked at Liao Chengwen and gave his opinion with firm eyes.

This immediately silenced Liao Chengwen.

Current electro-galvanizing will show some red rust after 240 hours of salt spray test.

As a result, Jiang Hui said that the Dacromet surface treatment process can prevent parts from showing red rust even after 1200 hours of salt spray testing.

People who work in technology are very aware of this gap, which is bigger than one can imagine.

It's like you are still using bronze to make weapons, while others are already using special steel to produce various swords.

It's definitely a technology with generational differences.

"Xiao Jiang, can you briefly introduce Dacromet surface treatment technology?"

If you don’t understand, just ask. Although Liao Chengwen still had some doubts about the truthfulness of what Jiang Hui said, he was still willing to listen.

If there really is such an amazing surface treatment technology, it would definitely be a big deal for China's industrial industry.

This not only solves the corrosion resistance problem of wheel bolts, but also solves the corrosion resistance problem of many metals.

Once it is popularized, the economic benefits generated by the annual savings in steel will definitely be in the billions.

Even the value it creates cannot be measured in terms of money.

"The good corrosion resistance of Dacromet surface treatment is closely related to its anti-corrosion mechanism."

"I will use the protective effect of Dacromet film on steel substrate as an example to summarize the relevant situation."

Jiang Hui knew that if he didn't explain the situation clearly today, Liao Chengwen would not let it go.

After all, the anti-corrosion effect that I mentioned is really amazing to people of this era.

Historically, China did not introduce Dacromet technology until the 1990s, and now the right to use it in the entire Asian region is monopolized by Japanese companies.

"As I mentioned just now, the Dacromet coating solution includes metal powder, solvent, passivating agent and special organic matter."

"After treatment, the Dacromet coating will produce a barrier effect. This is because the overlapping of flaky zinc and aluminum layers hinders the process of corrosive media such as water and oxygen reaching the substrate, and can play an isolating shielding role."

"In addition, during the Dacromet treatment process, chromic acid reacts chemically with zinc, aluminum powder and base metal to form a dense passivation film, which has good corrosion resistance."

"Finally, the main protective function of the zinc-aluminum-chromium coating is the same as that of the galvanized layer, which is to provide cathodic protection for the substrate. It can provide a protective effect many times better than that of electroplated zinc."

"When the above three effects are combined, the effect is extraordinary."

Jiang Hui quickly explained the anti-corrosion mechanism of Dacromet surface treatment, at least letting Liao Chengwen know that theoretically, this exaggerated surface treatment technology is possible.

"Since the benefits of Dacromet surface treatment technology are so great, is it possible for us to develop this technology?"

Liao Chengwen felt a little guilty when he said this, because after listening to Jiang Hui's words, he had no idea how to implement the Dacromet surface treatment technology.

In the end, the situation will definitely depend on Jiang Hui's performance.

“Of course we have to make it, but during the research and development process we need to confirm some coating and processing parameters.”

"Our factory's conditions in this regard are not particularly perfect. I will sort out the situation later and communicate with the Capital Institute of Technology to see if I can trouble them to help come up with a solution for this surface treatment technology."

When something good happens, you must think of your father-in-law. Dacromet surface treatment technology may seem insignificant, and 99.99% of people have never heard of it.

But once it is promoted in China, the economic significance will be extraordinary.

If Zhu Jiansheng could take credit for this achievement, it might have an unexpected effect on his future career development.

4MT manual transmission, "Hummer" project, Dacromet surface treatment process...

One major achievement after another will definitely push Zhu Jiansheng to continue moving forward.

Even if his father-in-law is unwilling, Jiang Hui is ready to give it a push!
"Okay, since you have already made arrangements, I feel relieved."

"But time waits for no one. The Dacromet surface treatment process must be finalized as soon as possible, otherwise it may not be able to be installed on the prototype vehicle."

After giving a few instructions, Liao Chengwen left Jiang Hui's office.

Thinking that he and Chen Chenxing had to go to the Japanese Embassy to repair the car this weekend, Jiang Hui picked up the phone directly and prepared to let Zhu Jiansheng get things done first.

Capital Institute of Technology has material-related majors, and their laboratories are equipped to produce the coatings needed for Dacromet surface treatment.

Some other majors, such as vehicle engineering, also have research on surface treatment processes.

Jiang Hui felt that the problem was not serious after handing the project over to Zhu Jiansheng to lead.

Anyway, I am very clear about the complete process flow and coating requirements of the Dacromet surface treatment process. At worst, I can just let the other party generate it directly according to the results.

First figure out what is and isn't there, then figure out why each parameter is set that way.

"Dad, it's me."

After wasting more than ten minutes, Jiang Hui finally got through to Zhu Jiansheng's office.

As the acting director of the Department of Vehicle Engineering, Zhu Jiansheng also has his own independent office.

"Xiao Jiang, what's wrong? What happened?"

Zhu Jiansheng's tone was obviously a little nervous.

Since going to work at the Capital Automobile Manufacturing Plant, Jiang Hui almost never called Zhu Jiansheng during working hours.

It is normal for Zhu Jiansheng to be nervous when he suddenly receives a phone call.

"Dad, there is a project that I need your help organizing..."

Jiang Hui quickly told Liao Chengwen about his visit to Chaoyang Fastener Factory today to confirm the new BJ212 wheel bolts, and then mentioned the Dacromet surface treatment process.

It took more than ten minutes in total, and Jiang Hui gave a brief overview of the Dacromet surface treatment process, giving Zhu Jiansheng a basic concept.

Zhu Jiansheng also took note of several key coating materials and precautions during the surface treatment process.

"If this Dacromet surface treatment technology is really that good, it will be of great significance."

"I will immediately write a report to the college and coordinate with other departments to research this technology."

Zhu Jiansheng knew that his son-in-law was trying to bring him credit again.

But this is not the time to be humble, let's get things done first.
