Abstract

The invention discloses a processing method capable of improving the hot corrosion resistance of a diamond grinding material. The processing method comprises the following steps: S1, after washing a diamond, drying; then immersing the diamond into TiO2 sol; after standing, taking out the diamond; then drying to obtain a material A; S2, putting the material A into phenolic aldehyde sol; after standing, taking out the material A and drying to obtain a material B; S3, putting the material B into silicon dioxide sol; after standing, taking out the material B; then drying, raising the temperature and carrying out heat insulation; then cooling and carrying out heat insulation; then cooling to room temperature. According to the processing method capable of improving the hot corrosion resistance of the diamond grinding material, provided by the invention, the prepared diamond grinding material has good hot corrosion resistance and toughness and the service life of the diamond grinding materialcan be prolonged.

Description

Technical field [0001] The invention relates to the technical field of diamond materials, in particular to a processing method for improving the thermal corrosion resistance of diamond abrasives. Background technique [0002] In recent years, with the advancement of science and technology, people's requirements for production tools are developing in the direction of high efficiency, long life, and high economy. In many fields, tools made of ordinary materials can no longer meet the increasing requirements of workers. Diamond has excellent properties and a wide range of uses. It is often used in mechanical processing, automobile manufacturing, aerospace, biology, medical equipment, electronic information, construction, transportation and other fields. In the prior art, diamond abrasives have poor thermal corrosion resistance and toughness, and cannot meet market demands. Summary of the invention [0003] Based on the technical problems existing in the background technology, the pr...
