Technical Field
The invention belongs to the technical field of automobile parts, and particularly relates to an automobile part containing a wear-resistant coating.
Background
The metal material is the most widely used engineering material, but with the increasingly harsh working conditions of engineering equipment, the single metal material has been difficult to meet the engineering use requirements. The wear-resistant coating is coated on the surface of the metal, so that the synthesized composite material can retain the strength and toughness of the metal, has the characteristics of wear resistance, corrosion resistance, high temperature resistance and the like of the coating, and can greatly improve the service performance of the material.
The methods for preparing the composite coating, which are commonly used in the industry at present, include the following methods: self-propagating high temperature synthesis, thermal spray coating, sol-gel process, and the like. The self-propagating high-temperature synthesis method is to use the high chemical reaction heat generated among reactants to promote the reactants to carry out continuous spontaneous chemical reaction to prepare the ceramic coating, and the single self-propagating high-temperature synthesis method can prepare the high-performance composite material coating, but the prepared coating has poor surface precision, and has the problems of uneven surface, gaps and the like. The thermal spraying technology is a coating method of melting and atomizing a coating material at a high temperature to form a particle flow in a molten or semi-molten state, and spraying the particle flow on the surface of a metal steel plate at an extremely high speed, so that a coating with good performances such as wear resistance, hardness and heat conduction can be prepared, and the influence on the thermal deformation of the steel plate is small. The sol-gel method is that metal alkoxide or inorganic salt which is easy to hydrolyze reacts with water in a certain solvent, forms sol through hydrolytic polycondensation, coats the sol on the surface of a metal steel plate, and forms a coating after drying and heat treatment.
