Abstract

The invention discloses a preparation method of a high-abrasion-resistant titanium alloy surface with a rose petal effect. The preparation method is implemented specifically according to the following steps: step 1, pretreating the titanium alloy surface; step 2, constructing a titanium alloy surface microstructure; step 3, carrying out electrophoretic deposition treatment; and step 4, carrying out fluoridation treatment, so as to obtain the high-adhesion surface finally. Through the preparation method, the problem about the creeping loss of a lubricant during mechanical lubrication in the prior art can be solved.

Description

technical field [0001] The invention belongs to the technical field of wettability surface design and preparation, and in particular relates to a preparation method for a highly wear-resistant rose petal effect titanium alloy surface. Background technique [0002] With the rapid development of aerospace technology, the development of long-lived spacecraft has become a hot and difficult point in the field of aerospace research. Whether the spacecraft can operate normally, reach the expected life span or even prolong its life depends to a large extent on the moving parts of the space equipment. Whether it can function normally and achieve the expected life. Lubricating materials and lubrication systems of spacecraft must withstand the test of various factors such as high vacuum in space, charged particle radiation in space, high and low temperature thermal cycles, and microgravity. At present, the lubrication methods of space moving parts mainly include liquid lubrication and...
