Thermal stable pcd manufacturers tell you that the grade quality, particle size and concentration of diamond have a decisive effect on diamond tools. In terms of diamond synthesis in our country, the six-sided topping large tonnage technology has matured, and the two-sided topping diamond synthesis has begun to take shape, and the production of powder catalyst synthesis, carbon and pyrophyllite block raw materials has been continuously improved. Therefore, for the manufacture of diamond tools in my country, Thermal stable pcd manufacturers tell you that it is entirely possible to synthesize diamonds with stable performance, coarse particles, and good thermal stability in batches.

Thermal stable pcd manufacturers tell you that one of the key factors to improve the cutting efficiency and life of diamond saw blades is to improve the diamond's holding power of the matrix. The carcass has a good holding force on the diamond, the diamond will not fall off prematurely, and has a large protrusion height, which is sharp during cutting and high efficiency.
There are generally three methods to improve the diamond holding power of ultra-thin diamond cutting discs:
(1) Improve mechanical control. Thermal stable pcd manufacturers tell you that this is because the metal powder shrinks during sintering, forming a compressive stress to hold the diamond. Compressive stress is caused by the difference in thermal expansion coefficient of diamond and matrix metal, and the volume change caused by crystal formation and growth during sintering. Due to the limited yield strength of the carcass, the resulting compressive stress and mechanical holding force are limited.
(2) A small amount of strong carbide forming elements such as Cr, W, Mo, etc. are added to the powder. The thermal stable pcd manufacturer tells you that because of its good wettability and affinity for diamond, carbonization is formed on the interface between diamond and matrix metal during sintering. It realizes the secondary gold bonding of diamond, which is conducive to strengthening and improving the holding power.
(3) A layer of strong carbide is plated on the diamond surface to form metallic elements such as Cr, Ni, Ti, W and so on. Thermal stable pcd manufacturers tell you that this is a process that has been adopted more in recent years.
In the production of special saw blades, it is advisable to use ultra-fine metal powder and pre-alloyed powder. Thermal stable pcd manufacturers tell you that the refinement of metal powder is beneficial to reduce the sintering temperature and increase the hardness. The use of pre-alloyed powder can prevent the premature loss and segregation of low melting point metals. Thermal stable pcd tells you that it is beneficial to the elastic limit and yield strength of sintered products, increases the holding power of diamond, and can also reduce the sintering temperature and holding time.
