Surface Treatment Technology: A Key Means to Upgrade Metal Properties​

1.Introduction to Surface Treatment Technology​
Surface treatment is a technology that modifies or covers the metal surface through physical, chemical and other methods. It can improve the corrosion resistance, wear resistance and other properties of metals. It is applicable to iron and steel, aluminum alloys, etc., among which iron and steel are the most widely used.​
2.Main Process Types​
2.1 Electroplating: It uses electrolysis to deposit metal or alloy coatings, such as galvanizing and chromium plating, and is used for anti-corrosion and decoration of auto parts, etc.​
2.2 Coating: It applies coatings to form a protective film, including paint coating and powder coating, etc. It is used for building steel structures, etc., and has both protective and aesthetic functions.​
2.3 Heat treatment: It changes the surface structure through heating, such as carburizing and nitriding, to improve hardness and wear resistance, and is used for gears, etc.​
3.Technical Advantages​
It can improve performance in a targeted manner, with flexible processes, controllable costs, and can extend the service life of products.​
4.Industry Applications​
It is applied in automotive, machinery manufacturing, electronic appliances, construction, aerospace and other fields, such as body coating and tool coating.
