Tungsten Disulfide Coating Thickness

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.

Coating thickness is an important process parameter, which plays an important role in product quality, process control and cost control. When the coating is too thin, the special function and performance of the material will be exploited difficultly. And if the coating is too thick, it will not only cause economic waste, but affect the bonding strength of the coating. Therefore, the detection of coating thickness is often very important.

So how to measure the coating thickness? Technicians use many different methods or instruments to measure coating thickness, including magnetic thickness gauge, eddy current thickness gauge, ultrasonic thickness gauge and micrometer thickness gauge. Among them, magnetic thickness gauge is suitable for the thickness measurement of non-magnetic coatings. It is a frequently-used kind of instrument. In order to take an appropriate measuring method of coating thickness, some factors should be taken into account. They are coating type, matrix material and coating thickness range, the shape and size of the measured parts, measurement cost and so on.

Tungsten disulfide is a kind of solid lubrication material with good lubrication performance, high temperature and extreme pressure resistance and wear resistance. It is closely connected with its coating thickness. With the thin thickness, tungsten disulfide can be absorbed well on the metal matrix surface and lubricate them well. When it is used for surface treatment of parts, it causes little effect. And when the coating surface is damaged, it still has lubrication function, which greatly ensures the service lives of mechanical parts. Tungsten disulfide coating with thin thickness has very high application value in mechanical lubrication, isothermal forging, plastic processing and other important fields.
