Problems solved by technology

[0003] However, ordinary coating materials have shortcomings such as impermanence, easy aging, easy falling off or insufficient strength, and high temperature resistance, and during the coating process, the coating will produce toxic substances that are harmful to human health or environmental safety. The coating process has been continuously improved and perfected, but the composition of the coating is not strict and reasonable enough, and there are still potential safety hazards, which need to be further improved and improved

Abstract

The invention discloses a preparation method of high-performance steel-based coating powder. The preparation method comprises the following steps: a) raw material screening, b) grinding pretreatment, c) mixing grinding, d) vacuum drying treatment. The preparation method of the high-performance steel-based coating powder, disclosed by the invention, is reasonable in process arrangement, simple and convenient in preparation process, and medium in cost. Enough corrosion resistant, heat resistant and wear resistant compounds are formed by the powder on the surface of a steel matrix. After the coating is formed by the powder on the surface of a part, all the performance requirements are met when the part runs in high speed, corrosion and high intensity environments.

Description

technical field [0001] The invention relates to a method for preparing a steel-based coating powder, in particular to a method for preparing a steel-based coating powder with excellent heat resistance, corrosion resistance and wear resistance, and belongs to the technical field of coatings. Background technique [0002] With the high-speed development of the machinery industry, the number of mechanical equipment operating in harsh environments such as high speed, high temperature, and corrosion continues to increase. Therefore, modern machinery has more and more technical requirements for parts such as wear resistance, corrosion resistance, and high temperature resistance. Come too high. People usually use a layer of other metal or alloy materials on the surface of steel-based parts, such as zinc, nickel, chromium, copper, cobalt, etc., to achieve or improve the corrosion resistance, wear resistance, oxidation resistance, etc. of the base metal. aspects of performance.
