Analysis of Diamond Surface Treatment

The diamond surface metallization treatment can improve the chemical stability, thermal stability, and the adhesion of the carcass to the diamond. This part of the work of our country is completed in the diamond tool manufacturers, which is not conducive to the serialization and specialization of diamond products. It also brings difficulties for the tool manufacturers to choose the right abrasive. As for the sintering process, for products with high product performance requirements, foreign countries tend to use vacuum hot-press sintering. Vacuum hot-press sintering has advantages compared with general hot-press sintering: reducing the oxidation of J' diamond, correspondingly increasing the high-temperature performance of the diamond, lowering the sintering temperature, increasing the density and mechanical properties of the sintered product, and reducing the consumption of the graphite die. Therefore, it can be said that vacuum sintering is a very promising sintering process.

The development trend of superhard material products Since the reform and opening up, the investment in finding a country’s infrastructure has greatly increased. Especially after the Asian financial crisis, China has increased its investment in infrastructure to promote domestic demand. The development of industrial technology urgently requires us to research and produce tools that are matched with it. The rich profit returns of PCD and PCBN are also the direct cause of many companies investing in this area. The international professional saw blade market is also a huge market for diamond products. With the large size and ultra-thinness of stone materials, the use of frame saws, wire saws, and group saws has become more and more widespread, and there is a tendency to replace some circular saws.

After China enters the WTO, the trade barriers between China and other countries will be gradually eliminated. The cost of equipment and raw materials imports will also be reduced. Together with the improvement of their own technology and cheap labor, China will gradually occupy the world's professional saw blade market. Since the late 1980s, the development of diamond thin films and their products has created an upsurge in China.

A diamond film is a fully crystalline polycrystalline pure diamond material that is produced using physical or (and) chemical methods. It has the advantages of high hardness, good wear resistance, high electrical insulation, high thermal conductivity, high chemical stability, etc. It is considered to be a good choice for semiconductor materials. With the continuous development of diamond film technology. It will play a major role in semiconductors, optical devices and other fields. In summary,

(1) The iron-based, ultra-thinning and pre-alloying of the diamond saw blade head will gradually be accepted by the diamond tool manufacturers. Conversely, this will greatly improve the performance of the saw blade and enhance the international competitiveness of China's diamond saw blade.

(2) Abrasive granulation and surface metallization techniques will be widely used in metal-based tools.

(3) Vacuum sintering and high-temperature brazing techniques have gradually matured, and they have emerged in the manufacture of products with special requirements.

(4) The professional saw blade and engineering thin-wall drilling market has a vast space and the technology is gradually mature.

(5) PCD, PCBN and their products will be widely used in mechanical processing, wood processing and other industries.
