Abstract

The invention discloses a method for preparing a coating by induction sintering method for electron beam cladding. Paste or paste powder is extruded on the surface of a base material to be clad by metal injection molding, and then induction sintering is used. To form a preset layer, electron beam cladding is performed on the preset layer to obtain a composite coating, and finally the composite coating is subjected to heat treatment. The worthy coating of the present invention has better mechanical properties. Aiming at the friction and wear of the ball head and the acetabulum of the artificial hip joint friction pair and the quality problems of the bonding layer, the present invention provides a method for preparing a coating by induction sintering for electron beam cladding and the prepared graphene doped The diamond coating improves the hardness of the surface of the artificial hip joint, the bonding strength of the film / base, the performance of wear resistance and corrosion resistance and good biocompatibility, and solves the problems of the metal material in the prior art.

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...
