Silicon carbide has stable chemical properties, high thermal conductivity, low thermal expansion coefficient, good wear resistance, large pores, Mohs pores 9.5, and can resist oxidation at high temperatures.
The carbide SiC on the diamond silicon coating has formed a bond with the diamond - bonded to form a whole. It will not fall off during the impact test. The diamond is broken into several petals, and the coating is still covering it. It can be seen that its degree of maturity is because silicon forms SiC on the surface of the diamond. The particle size range is 325/400-20/30, and the weight gain ratio is 2%-3%.
The plating particle size range is 20/25 to 500/600, and the micron powder is 30-40 to 6-10 microns.
The main functions of diamond coated silicon carbide include improving the overall thermal conductivity of the composite substrate and enhancing the stability and thermal properties of the material.Diamond coated silicon carbide can reduce the interfacial thermal resistance between layers by setting an interface layer between the silicon carbide substrate layer and the polycrystalline diamond layer, thereby improving the overall thermal conductivity of the composite substrate. This design not only improves thermal conductivity, but also reduces the difference between the silicon carbide substrate layer and the polycrystalline diamond layer, avoiding the problem of delamination between the two, thereby obtaining a composite substrate with complete crystal morphology.
In addition,diamond coated silicon carbide composite materials combine the high thermal conductivity of diamond with the excellent properties of silicon carbide, possessing advantages such as high thermal conductivity, high hardness, high modulus, high temperature resistance, and thermal shock resistance.This composite material plays an important role in aerospace, new energy-saving vehicles and other fields.
