Abstract

The invention belongs to the technical field of coating, relates to a vacuum electron beam coating method and aims to provide a low-cost, pollution-free, high-efficiency and high-quality thick coatingmethod. The method in which vacuum electron beam coating is adopted includes steps: adding coating metal into a vacuum electron beam coating device, taking an iron-base material as a substrate material, heating the substrate material to 400-1200 DEG C, setting electron beam power to be not smaller than 20KW, controlling a vacuum degree of an operating cavity of an electron beam furnace in a rangeof 10-10<-3>Pa, coating, and cooling to 300 DEG C or below to obtain a coating composite material. By adoption of the vacuum electron beam coating method, the coating composite material high in coating thickness and resistant to corrosion can be obtained, and low cost, freeness of pollution, high speed and high efficiency are realized.

Description

technical field [0001] The invention belongs to the technical field of coating, and in particular relates to a vacuum electron beam coating method. Background technique [0002] Titanium is a silver-white metal, which has the advantages of low density, high specific strength, corrosion resistance, and non-toxicity. , connective tissue well combined, but the best biocompatible metal material. [0003] However, there are still great difficulties in metallurgy and material processing of titanium, and the cost is very high, which makes it difficult for titanium metal to be widely used in civil and industrial applications. At present, the anti-environmental corrosion materials used by a large number of civil and industrial uses are various types of stainless steel. However, in some places with serious environmental pollution, even 304, which has excellent corrosion resistance, will rust. Especially in medical applications, stainless steel is also widely used as a bone repair m...
