Abstract

The invention discloses a preparation method for magnetron sputtering a TiMo film on a titanium alloy surface, which is characterized in that the preparation method comprises the steps of pre-sputtering treatment, substrate installation, sputtering and film forming, etc. Compared with the prior art, the invention realizes the purpose of preparing a Ti-Mo film on a titanium alloy surface by the magnetron sputtering process; a film with a thickness of 1-50 microns can be obtained by controlling the process conditions, and the film has good compactness, good bonding force with the substrate, anda controllable thickness; and a film with a uniform thickness can be obtained on a large-area substrate. The coating prepared by the invention has excellent resistance to salt spray corrosion even ata temperature of 600 DEG C, and the used preparation method can produce high-quality products with the guarantee of batch production.

Description

technical field [0001] The invention relates to a vacuum coating method on a metal surface, in particular to a method for preparing a TiMo film by magnetron sputtering on the surface of a titanium alloy. Background technique [0002] Titanium alloys are widely used in aero-engine parts due to their high specific strength and good corrosion resistance. The high-thrust ratio aero-engine compressor will use titanium alloy, but the titanium alloy itself is soft and has poor erosion resistance. Cause serious erosion damage, damage the engine performance structurally and aerodynamically, and seriously lead to engine failure. Coating a certain protective coating can improve the wear resistance and corrosion resistance of titanium alloy, prolong the service life of the compressor, and improve its working reliability. Many methods can be used to apply the protective coating, such as infiltration plating, plasma spraying, magnetron sputtering coating, etc. Among them, magnetron spu...
