Abstract

The invention relates to a method for coating membranes on artificial diamond particles, in particular to a method for coating nickel-phosphorus alloy membranes on artificial diamond particles for a cutter head of a diamond circular cutting saw blade through chemical deposition. The method comprises the following steps of: deoiling, sensitizing and activating the diamond particles, and plating nickel-phosphorus alloy by using a chemical method to obtain the diamond particles of which the surfaces are coated with the nickel-phosphorus alloy membranes. By the method for coating the membranes on the artificial diamond particles, the cutting life of the cutter head of the diamond circular cutting saw blade is prolonged greatly, and the production cost is reduced; and the artificial diamond particles are coated with the membranes, the cost is low, the pollution is light, and the method is easy to operate and master.

Description

technical field [0001] The invention relates to a method for coating artificial diamond particles, in particular to a method for treating artificial diamond particles used in diamond circular saw blades and chemically depositing and coating nickel-phosphorus alloy on the artificial diamond particles. Background technique [0002] The existing domestic diamond circular saw blade wears quickly when used, and the cutting effect is poor. After analysis, the reason for the wear of the cutter head is that the artificial diamond particles in the cutter head ingredients fall off, so that the cutting performance of the diamond particles is not well exerted. The main reason for the failure of foreign mature diamond circular saw blades is the wear of artificial diamond particles. During the wear process, the high hardness and high wear resistance of artificial diamond particles are better played. It can be seen from the relevant data that foreign countries use laser sintering and othe...
