In order to let more people know about polishing and grinding, Honway update the knowledge column from time to time.
Diamond Synthesis Method Diamonds can be synthesized by gas-phase methods (e.g., PVD or CVD), liquid-phase methods (e.g., hydrostatic, catalytic, or CVD liquid-phase methods), or solid-phase methods. The solid-phase method is the synthesis of diamonds in a material with no fluid. The solid carbon atoms cannot diffuse through the fluid to reorganize into the structure of …

Fluorine rubber and nitrile butadiene rubber were modified by using purified and post-blasted synthetic products (nano-diamond black powder and gray powder). The study shows that although the black powder can increase the hardness of rubber, but the tensile strength and elongation at tear decreased. Nano diamond powder gray powder added to the fluorine rubber, the …
In 1992, Yashchenko and others in the United States used powder metallurgy to make a new type of anti-wear material, which is made by mixing copper-zinc and copper-tin powders with nano-diamond powder in a certain proportion by compaction, and then sintered in hydrogen gas. This new material can be used in internal combustion engine cylinder …

（1）Nano Diamond Powder Composite Coating Nano Diamond Powder Composite Coating Technology is one of the key technologies for product manufacturing. Through surface coating, the surface of the product can be protected by a protective layer of controlled composition and organization, which significantly improves the service life and reliability of the product. For example: marine platforms, …
Cerium oxide is a significant rare earth oxide, mainly used for smelting metallic cerium and as an additive in various materials. Since 1940, cerium-rich rare earth polishing powders have gradually replaced iron oxide (red iron) for glass polishing, becoming a critical material in the glass polishing process. Compared to traditional polishing powders like iron oxide, …
Rare earth materials are widely used, in addition to cell phones, TV screens, stereos, and energy-saving light bulbs, which are closely related to our lives, they are also important materials for the production of many high-tech products, such as electric cars, magnetic levitation trains, the nuclear energy industry, …
