What is metal surface treatment arcor?

Arcor is salt bath carburizing, which is a surface treatment technology invented by HEF company in France.

This technology is the introduction of French HEF patents Shechev and Arco technology. SURSULF technology is characterized in that the concentration of active sulfur atoms in the salt bath is kept at a constant level, and the density and hardness of the bonding layer only depend on the contents of carbon and other alloying elements in the steel to be treated. After treatment, with the increase of alloying elements such as carbon in steel, the hardness gradient of diffusion layer becomes steep; The depth of the diffusion layer becomes smaller. In order to be applied to the occasions where high corrosion resistance is needed, ARCOR treatment process can be used as a supplement to Sheshev treatment process. It is a treatment process combining thermochemical diffusion, passivation and precision treatment in a salt bath furnace. A surface layer with high friction resistance, bite resistance, wear resistance, corrosion resistance and high fatigue strength is formed on the surface of the workpiece. It is suitable for any workpiece that needs to solve the problems of friction resistance, bite resistance, wear resistance and corrosion resistance, and is an ideal treatment process with low price.
