Abstract

The invention provides a high temperature resistant and abrasion resistant coating for a polishing mechanical arm and relates to the field of coating materials. A transition layer, a high temperature resistant layer and an abrasion resistant layer are arranged sequentially from the substrate surface to the outer surface of the coating. The transition layer is a CoFeCrNi coating with the thickness being 50-80 um, the high temperature resistant layer is a Si4N3-Cr3C2 coating with the thickness being 100-150 um and the abrasion resistant layer is a TiO2-Al2O3-TiB2-WC coating with the thickness being 150-220 um, and the transition layer, the high temperature resistant layer and the abrasion resistant layer are sprayed on the substrate surface through a plasma spraying method. According to the coating prepared by the invention, good adhesion between the coating and a substrate is achieved, so that the mechanical arm has good high temperature resistant and abrasion resistant performance, and the service life of the mechanical arm is prolonged.

Description

technical field [0001] The invention relates to the field of coating materials, in particular to a high-temperature-resistant and wear-resistant coating for a mechanical arm for grinding. Background technique [0002] With the continuous development of science and technology and the improvement of automation, the mechanical arm has gradually replaced the manual operation. It is widely used in machinery, medical, military, automobile, etc. due to its high flexibility, high labor intensity, durability and high production efficiency. in the industry. In the grinding industry, many young people are no longer willing to take up this kind of work because the dust of debris causes great harm to the human body and the efficiency of manual grinding is low, so the grinding work is gradually replaced by mechanical arms. Grinding robotic arms can improve product consistency and eliminate individual differences, increase productivity and efficiency, and are widely used in industrial pro...
