Manufacturing method of diamond compact with high thermal conductivity

Abstract

The invention relates to the technical field of manufacturing of diamonds, and provides a manufacturing method of a diamond compact with high thermal conductivity. The method comprises the following steps: preparing the following components in parts by weight: 62 to 68 parts of diamond micropowder, 28 to 32 parts of copper powder, and 4 to 6 parts of silver powder, wherein the fineness of the diamond micropowder, the copper powder and the silver powder is 80 to 170 meshes; uniformly mixing and stirring; placing the mixture into a metal cup; sintering at high temperature of 1150 to 1350 DEG C under high pressure of 5.5 to 6.5 GPa under a vacuum state, so as to obtain the diamond compact; 65 parts of diamond micropowder, 30 parts of copper powder, and 5 parts of silver powder are weighted. The diamond compact produced by the method has the advantages of being outstanding in heat conducting effect, and long in service life, and relatively reducing the abrasion.

Description

technical field [0001] The invention relates to the technical field of diamond manufacturing. Background technique [0002] The main component of the diamond composite sheet is diamond, and the diamond composite sheet is synthesized by diamond micropowder through high temperature and high pressure; in the prior art, due to the unreasonable composition inside, the diamond composite sheet generally has the disadvantage of low thermal conductivity, and it is easy to aggregate during use. The heat will affect the heat dissipation effect, and then affect its service life, which cannot meet the requirements of some production. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a method for manufacturing a diamond composite sheet with good heat dissipation effect, guaranteed service life, and meeting some production requirements—a method for manufacturing a diamond composite sheet with good thermal...
