Abstract

The invention belongs to the technical field of coating, relates to a vacuum electron beam double-roller pressing coating method and aims to provide a low-cost, pollution-free, high-efficiency and high-quality thick coating method. The method in which vacuum electron beam double-roller pressing coating is adopted includes steps: adding a coating material into a vacuum electron beam double-roller pressing coating device, heating a 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 beamfurnace in a range of 10-10<-3>Pa, coating, performing double-roller pressing in a coating process, and cooling to 300 DEG C or below to obtain a coating composite material. By adoption of the vacuumelectron beam double-roller pressing coating method, the coating composite material high in coating thickness and jointing force 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 film coating, and in particular relates to a method for vacuum electron beam-to-roll pressing film coating. 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...
