Coating thickness detection

 

The surface covering layer is used to make the surface of the material have certain reinforcement, protection (such as anti-oxidation and anti-corrosion) decoration or special functions (such as conductive, insulating and thermal insulation invisible, etc.), using other methods such as physics or chemistry, in metal or non-metal substrates. The surface is formed with one or more layers of a certain thickness and different from the base material to meet product design and use requirements. The cover layer consists of a coating, a non-metallic coating, a laminate, a chemically formed film, etc. to apply a coating to the surface of the material to achieve the special function and performance of the material. The protective layers commonly used in the industry are metal cover and non-metal cover.

 

Application field

 

Metal and oxide coating thickness measurement technology has a wide range of applications, mainly used in aviation, automotive, materials, metals, electronics, ceramics and other fields. In industrial production, if the thickness of the cover layer is too thin, it will be difficult to exert the special functions and properties of the material. If it is too thick, it will cause economic waste, and if the thickness of the cover layer is uneven or does not meet the specified requirements, it will be Mechanical physical properties have an adverse effect. Therefore, the uniformity of the thickness of the surface coating of the material and the composition of the material of the covering layer are the most important indicators of product quality. Testing the surface coating of materials has become the most important process necessary for the material processing industry and users to conduct product quality testing, and is an essential means for products to meet high quality standards.
