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 coating is a high quality solid lubricating material, which is related to its coating thickness. Tungsten disulfide coating with thin thickness can be used to treat the metal surfaces and prevent them from harm, having great application value in many fields.

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.

Tungsten disulfide coating is a continuous solid film coated by tungsten disulfide once. It is formed by spaying or blushing film-forming agent on the friction surface. And the film-forming agent is made from tungsten disulfide powder and organic binder or inorganic binder. Tungsten disulfide coating is regarded as the most promising solid lubrication coating.
