An important selling point of mobile phones is the UV coating in the manufacturer's propaganda. What is the UV coating? I think most players don't know much about it except that it looks shiny, and there will be many questions. Why do uv coatings wear and tear? Today, I'm going to popularize some basic knowledge about UV: UV curable (UV) coating is a kind of coating that uses short wavelength ultraviolet radiation to produce chemical effects and overlap to make three-dimensional bridging and hardening.

Atmospheric plasma spraying is a common process for depositing ceramic coatings to prevent wear and corrosion. Raw materials include, for example, alumina, titanium oxide and chromium oxide. Plasma sprayed chromium oxide coating is widely used in anilox rolls, pump seals and wear rings due to its good surface quality, high hardness and wear resistance.

Thermal spraying is a method of using heat source to heat spraying materials, atomizing, spraying and depositing molten or near-molten particles onto the surface of the substrate to form a special surface layer.

Thermal spraying is a technology that utilizes heat sources such as electric arc, plasma spraying and flame. In this design scheme, the volume of mass is analyzed, the powder or filamentous metal or non-metallic material is heated to the molten or semi-molten state, and then the flame itself or compressed air is sprayed on the surface of the pretreated substrate at a certain speed, and the multifunctional surface coating is formed by deposition.

Whether mechanical parts or metal components, the most prominent problem is surface wear or corrosion or both. Here is a brief introduction of the coating application guide: 1. Wear resistance - the largest application field of thermal spraying technology at high and low temperatures. This kind of coating is divided into the following types:
