Abstract

The invention discloses a process for tungsten plating on the surface of industrial diamond. The process comprises the following steps of (1) preparation of an adhesive; (2) preparation of coating powder; (3) material mixing through a plating formula; (4) evaporation and (5) separation. Through the process for tungsten plating on the surface of the industrial diamond, smoothness of evaporation is ensured, quality is stable and reliable, and the life of the tungsten layer on the surface is prolonged. In addition, the thickness of the coating on the surface of the diamond can be controlled through the process, and the application range of the tungsten-plated diamond is widened.

Description

technical field [0001] The invention belongs to the technical field of superhard materials, and in particular relates to a process method for plating tungsten on the surface of industrial diamonds. Background technique [0002] During the manufacture and use of industrial diamond cutting and drilling tools, the industrial diamond particles are eroded by air and tool matrix materials at high temperatures, and their strength will be significantly reduced; most industrial diamond particles are subjected to grinding forces when the tools are in use. detach from the substrate. The surface of industrial diamonds is coated with a metal coating, which can effectively improve the bonding strength of industrial diamond crystal particles and the metal material of the tool base through chemical bonding; the isolation effect of the metal film layer on industrial diamonds protects them from high-temperature sintering and high-temperature grinding. Erosion by air and binders. Extend the ...
