Special coatings and surface treatments are obtained through galvanic, chemical and electrochemical processes.
Manganese phosphating is a surface treatment that guarantees an excellent resistance to corrosion combined with self-lubricating effects, reducing the friction between surfaces of mechanical sliding parts.
The nickel electrodeposition guarantees an excellent resistance to corrosion combined with resistance to wear. Combined with other elements such as diamond it is used in the field of special tools.
