Description

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