Super hard abrasive development trend at home and abroad

Abstract Superabrasives mainly refer to diamond and cubic boron nitride. Diamond is currently the hardest material in the world. The hardness of CBN is second only to diamond.

Superabrasives mainly refer to diamond and cubic boron nitride, which is currently the hardest material in the world. The hardness of CBN is second only to diamond. The hardness of these two superabrasives is much higher than the hardness of other materials, including abrasive materials, corundum, silicon carbide, and hard tool materials such as tool materials such as carbide and high-speed steel. Fenike Superhard Superhard Materials Co., Ltd. is China's largest CBN abrasives manufacturer with advanced production equipment and superb CBN abrasive technology, which is highly authoritative in the superhard materials industry. The following is a comparison of diamond and cubic boron nitride in appearance:


First, the status quo of superhard abrasive application


Second, the development trend of superhard abrasives

In general, both domestic and foreign superhard materials are developing in the direction of high quality, multi-variety and specialization. The main development trends are:

1. Single crystal synthesis - using different raw materials (graphite and catalyst alloys of different compositions and forms), different high temperature and high pressure synthesis equipment (two-sided top and six-sided top) and different processes to synthesize different single crystal products

2. Single crystal separation—Synthetic single crystal products are sorted according to different particle size, particle size, bulk density, and strength and toughness, and are classified into different single crystal varieties.

3. Surface Plating - After sorting different types of single crystals, metal plating (single metal or alloy) of different types and thicknesses is plated on the surface of the crystal by electroless plating, electroplating, vacuum plating, etc. , single or multi-layer), making it a diamond or CBN variety with different properties and different uses

4. Microcrystal preparation—CBN crystallites are polycrystalline abrasive grains composed of numerous submicron-sized single crystal CBNs with sizes ranging from 0.1 to 0.8 mm. Their properties are isotropic, the structure is quite dense, and they have high hardness and high wear resistance. Sex

5. Thin Film Manufacturing—Using vapor deposition growth to produce ultra-hard material films with special properties and oversized sizes, opening up new avenues for diamond manufacturing and new applications

Third, super hard abrasives and products are mainly produced in the country
