Lubricious tungsten disulfide can be used under complex working conditions such as high temperature, high pressure and vacuum. Therefore, it can be applied in lubrication of Mars probe parts to ensure their long-term work.

Coating thickness of tungsten disulfide can be measured by a main type of magnetic thickness gauge, magnetic or electromagnetic induction thickness gauge. Tungsten disulfide coating with diamagnetism is usually applied to protect the metal surfaces.

Tungsten disulfide can be used in the lubrication of lens tube to prolong its service life. Lens tube is the main rotating part of infrared thermal imager. It is important to provide stable lubrication for the lens tube as the working environment of infrared thermal imager is complex.

As tungsten disulfide has diamagnetism, its coating thickness can be successfully measured by magnetic stretching thickness gauge. And magnetic stretching thickness gauge is a main kind of magnetic thickness gauge.
