Description

technical field

[0001] The invention relates to the technical field of chemical industry, in particular to a fluidized bed device and method for coating the surface of diamond powder. Background technique

[0002] Diamond powder is the hardest material in industrial production, and its hardness characteristics are usually used as processing and grinding materials widely. Many of its excellent properties have been gradually discovered and excavated, such as high thermal conductivity at room temperature, extremely low thermal expansion coefficient, low friction coefficient, good chemical stability, large band gap, and high sound propagation speed. It has a broad application market in the fields of electronic industry, mechanical processing, geological drilling and mining industry.

[0003] However, when diamond powder is processed or applied at high temperature, it is prone to graphitization, which will greatly reduce its mechanical strength, so it needs to be coated on its s...
