Abstract

The invention belongs to the technical field of metal coatings, and particularly relates to a wear-resistant metal coating and a preparation method thereof. The wear-resistant metal coating comprises tungsten carbide, nanometer aluminum oxide, titanium tin carbon, silicon dioxide, titanium dioxide, nanometer thorium dioxide, smoothing powder and hardening powder, wherein the smoothing powder comprises molybdenum oxydialkyldithiophosphate sulfide, zinc dialkyldithiophosphate, polyvinyl chloride, nickel ferrite modified carbon black and lithium nickel manganate, and the hardening powder comprises ethylene wax, vanadium diboride, graphene, a silane coupling agent and epoxy resin. The smooth degree of a plating layer is greatly improved, the friction coefficient of the coating is reduced, and the friction force borne by the coating is reduced in the friction process of the coating, so that the service life of the coating is prolonged, the prepared hardening powder is added into coating powder to be sprayed, the surface hardness of the formed coating is improved, the hardness of the coating is improved, the wear resistance and scratch resistance of the coating are greatly improved, and the service life of the metal coating is prolonged.

Description

technical field [0001] The invention relates to the technical field of metal coatings, in particular to a wear-resistant metal coating and a preparation method thereof. Background technique [0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. The paint can be gaseous, liquid, or solid, and the type and state of the paint are usually determined according to the substrate to be sprayed. With the development of social science and technology and the increasingly extreme requirements for the operating environment of machinery in aviation, navigation, and industry, mechanical moving parts are facing serious friction and wear problems, so high-performance wear-resistant and corrosion-resistant coatings are required to provide protection. On the other hand, machinery in all walks of life is currently developing towar...
