Advantages of metal surface coating include the following:
1. Anti-corrosion: After the metal surface is coated with a film, a protective film will be formed on the surface to prevent the chemical substances such as oxygen and water in the environment from corroding the metal surface, so that the metal surface will remain bright and beautiful for a long time.
2. Improve hardness: Metal surface coating can increase its hardness and enhance its wear resistance. Some metal surface coating materials have high hardness, which can prevent the metal surface from being scratched or worn.
3. Improve electrical conductivity: Some metal surface coating materials have good electrical conductivity, which can protect the metal surface without affecting its electrical conductivity.
4. Improve temperature resistance: Some metal surface coating materials have high temperature resistance and high temperature resistance, which can make the metal maintain better performance in high temperature environments.
5. Prevent bacterial growth: Some metal surface coating materials have antibacterial properties, which can prevent bacteria and microorganisms from growing on their surfaces and keep the environment hygienic.
