The world's hardest steel-nano-diamond particle reinforced steel-based composite material is expected to be industrialized in Huizhou

Two days later, the second China Science and Technology Fair will open. Looking back at the first session of the CST, how was the progress of nearly 700 results transformation projects signed at that time? Recently, Nanfang Daily visited the “Nano Diamond Particle Reinforced Steel Matrix Composites Industrialization” project, its first intentional investment amount is 500 million yuan, which is the first The project with the highest contracted value of the results of the trade fair.

The project was signed by the former president of Shenyang Polytechnic University, Jia Chunde, and a company in Beijing. Huizhou Carbon Light Material Technology Co., Ltd. has been established to specialize in industrialization. At the same time, Carbon Light also signed a contract with the Chinese University (South China) Science and Technology Achievement Transformation Center to build a metal nanocomposite research institute in Huizhou, becoming a research and development base for such products.

Occasionally found that nano-diamond and metal are tightly combined

Into the Huizhou City Wuhu Ecological and Intelligent District Innovation Park, in the laboratory of the Institute of Metal Nanocomposites, you can see some square, cylindrical or shaped metal blocks. It feels a bit cold when touched, and it is quite heavy, and it is no different from ordinary metal. It is not conspicuous in the laboratory. It is marked with letters and numbers.

Jia Chunde told reporters that this can be said to be the hardest steel in the world. The letters and numbers above indicate its hardness. In June last year, Jia Chunde took part in the first China University Science and Technology Achievements Fair held in Huizhou with its technical achievements, and then signed a 500 million yuan achievement transformation project, becoming the project with the highest intention to sign the contract.

Jia Chunde introduced that in 1985, he was a visiting scholar in the Department of Materials Science and Engineering at a university in Canada, mainly doing dynamic direct observation of wear and tear. The study found that the diamond particles in the electroplated diamond and the metal matrix are very tightly combined, and the ceramic can be ground as a composite material. So I came up with an idea, can I use it to develop steel-based composite materials?

Around 1990, Jia Chunde, who was the head of a company's engineering and technology center after returning to China, received the task of developing a special type of weapon for lubricating oil. At that time, Belarus had developed nanodiamonds, and there were reports that nanodiamonds as lubricant additives could improve the performance of lubricating oils. It has been found that this small particle of diamond can be transferred and deposited on the surface of metal parts to form a very strong protective film. This phenomenon reminds him that diamond and iron have natural affinity. In this case, can diamonds enter the steel matrix?

Later, Jia Chunde and the team developed a nano-diamond super-abrasive material after repeated experiments, and further confirmed that the nano-diamond did diffuse into the steel matrix by various testing methods. This is expected to make China into the forefront of the world's steel-based nanocomposites. Based on this major discovery, Jia Chunde, Yang Shutong and Duan Zhanqiang team invented the technology of nanodiamond particle reinforced steel matrix composites.

Jia Chunde introduced that this nano-composite structure of steel materials has extremely excellent mechanical and physical properties, hardness, strength, impact resistance, fatigue resistance, super wear resistance and good processability. Around 2005, the complete set of industrial production processes are nearing maturity and have the conditions for industrialization. Since then, because of some things to deal with, it is only in recent years that it has begun to promote its industrialization.

Expected to form a billion-dollar industry

The breakthrough of technology and the demand of the industry prompted Jia Chunde to explore the industrialization of nano-diamond. In June 2017, the first China Science and Technology Fair was held in Huizhou, and Jia Chunde signed a contract to carry out the transformation and industrialization of the results.

At present, his team has established a metal nanocomposite research institute with the South China Center, and will conduct research around nanodiamond technology. “We found that diamond can seep into the steel. It just found a 'gold mine' and a lot of work to develop this 'gold mine', so it will be developed after research.”

What can this technology do? Jia Chunde said that it can be applied in at least three areas, namely, steel materials, machinery manufacturing, and surface engineering.

At present, there are more than 200 kinds of steel in the world, and there are more than 2,000 special steels. About 80% of these steels can be turned into diamond-grain-reinforced steel-based composites, and their performance will be greatly improved. "Our special steel is not special, we must import a large number of high-performance special steel, such as steel for bearings, steel for gears, steel for high-temperature boilers, even automobile engines, etc., high-end automotive springs, etc." Therefore, this technology can be quite Solve the problem of high performance special steel.

In the field of machinery manufacturing, including construction machinery, coal machinery, road construction machinery, construction machinery, environmental protection machinery, energy machinery, fluid machinery, power transmission machinery, as well as defense equipment manufacturing and a large number of mechanical tools, the market is very important in every aspect. huge. There is also the field of surface engineering.

Jia Chunde believes that the "nano-diamond particles reinforced steel-based composite materials industrialization" project has broad prospects in these three areas, and the market potential is difficult to accurately estimate.

According to the plan, the project's intentional investment of 500 million yuan will build a metal nano composite materials research institute that integrates scientific research, new product and new technology pilot, high-end equipment research and development and professional personnel training. And relying on it, through the technical services, technology shares and other forms and related steel companies, machinery manufacturing companies to jointly create a national diamond super nano steel high-tech industrialization alliance and industrialization demonstration base, looking forward to the future industrialization demonstration base reached 1000 Output value of more than 100 million yuan. Jia Chunde said that this year, relevant funds will be in place, a batch of experimental equipment and equipment will be purchased, full-time scientific research personnel will be introduced, test bases will be established, and the industrialization process will be further accelerated.

Looking forward to getting more and better technology services

Nanfang Daily: At the first session of the Science Fair held last year, you signed a project with “a nano-diamond particle reinforced steel-based composite material industrialization” with a Beijing company. How has it progressed so far?

Jia Chunde: First of all, Huizhou Carbon Light Material Technology Co., Ltd. was established, which will specialize in the industrialization of nano-diamond technology. At the same time, it also established the Metal Nanocomposite Research Institute jointly with the South China Center and became the research and development base for such products. Of course, these two units are basically a team of more than 10 research backbones, each with their own strengths in related fields. In addition, we have also established an academician workstation for special materials.

Technical research can provide technical support for industrialization. In turn, industrialization can provide financial support for more in-depth technical research, and the two promote each other. When relevant funds are in place, the pace of research and industrialization will be accelerated.

Nanfang Daily: What is the application prospect of this technology?

Jia Chunde: Frankly speaking, this account is very difficult to calculate. It can be used in at least in the field of steel materials, machinery manufacturing, and surface engineering.

We are doing the most wear-resistant steel in the world, and maybe we can push the market within a year. There is now a research and development center. If it goes well, there will be 10 transfer bases in the periphery. They will be connected with several large factories, which constitutes the industrial cluster of diamond super nano steel. Our goal is to achieve an output value of 100 billion yuan, but the actual application prospects will far exceed this scale.

Nanfang Daily: Is there any idea or suggestion to promote this transformation and industrialization in Huizhou?

Jia Chunde: Due to the opportunity of the first fair, we are doing research and industrialization here. In the process of advancing, there are not enough technical services that I feel can be enjoyed. For example, in the project declaration, the introduction of academician workstations, etc., sometimes do not know where to find docking. It is hoped that Huizhou will strengthen its service work in this area and promote better and faster transformation of good results transformation projects.
