According to the classification method of thermal spraying coating by F.N.LONGO in the United States, the coating can be divided into:
1. Wear resistant coating
It includes anti adhesion wear, surface fatigue wear coating and erosion resistant coating. In some cases, there are wear resistant coatings against low temperature (< 538 ℃) and high temperature (538 ~ 843 ℃).
2. Heat resistant and oxidation resistant coating
The coating includes coatings applied in high temperature process (including oxidation atmosphere, corrosive gas, erosion above 843 ℃ and thermal barrier) and molten metal process (including molten zinc, molten aluminum, molten iron and steel, molten copper).
3. Atmospheric and immersion corrosion resistant coatings
Atmospheric corrosion includes corrosion caused by industrial atmosphere, Salt atmosphere and field atmosphere; Immersion corrosion includes corrosion caused by drinking fresh water, non drinking fresh water, hot fresh water, salt water, chemistry and food processing.
4. Conductive and resistive coatings
The coating is used for conductivity, resistance and shielding.
5. Restore size coating
The coating is used for iron-based (machinable and grindable carbon steel and corrosion-resistant steel) and non-ferrous metal (nickel, cobalt, copper, aluminum, titanium and their alloys) products.
6. Gap control coating for mechanical components
The coating is grindable.
7. Chemical resistant coating
Chemical corrosion includes the corrosion of various acids, alkalis, salts, various inorganic substances and various organic chemical media.
Among the above coating functions, wear-resistant coating, heat-resistant anti-oxidation coating and chemical corrosion-resistant coating are closely related to the production of metallurgical industry.
