Abstract

The invention discloses a method for an induction sintering method for preparing a coating with electron beam cladding and application. Mushy or pasty powder is extruded on a substrate surface to be subjected to cladding, then the induction sintering method is adopted for forming a preset layer, electron beam cladding is conducted on the preset layer, thus the composite coating is obtained, and finally heat treatment is conducted on the composite coating. The coating prepared with the method has good mechanical properties. Specific to frictional wear of bulbs and acetabulums of an artificial hip joint friction pair and the quality problem of a bonding layer, the method for the induction sintering method for preparing the coating with electron beam cladding is provided, the prepared graphene doped diamond coating is applied to improve hardness, film / substrate bonding strength, abrasion resistance, corrosion resistance and good biocompatibility of the surface of an artificial hip joint,and the problem of metal material of the prior art is solved.

Description

technical field [0001] The invention relates to the field of coating preparation, in particular to a method and application of an induction sintering method for preparing a coating by electron beam cladding. Background technique [0002] Cladding coating technology is a material surface treatment technology that can greatly improve the surface properties of workpieces. It has the advantages of high production efficiency, low production cost, and large-area cladding layers. It is widely used in industrial production. The preparation technologies of cladding coating mainly include laser cladding, argon arc cladding, plasma cladding, electron beam cladding and high frequency induction cladding. Compared with other cladding coating technologies, although the application cost of high-frequency induction cladding technology is lower, it can provide high power density, has highly flexible selectivity in heating surface and depth, does not produce physical pollution, and can be used...
