What are the general plating processes for hardware parts?

Electroplating of metal products can be described by the following process flow:
Loading→ degreasing, water washing → rust removal, water washing → activation, water washing → electroplating → water washing → drying → inspection → packaging.
Among the electroplating, common ones are: zinc plating, copper plating, nickel plating, gold plating, silver plating, tin plating, rhodium plating, palladium plating and alloy plating. It can be single-layer electroplating or multi-layer electroplating.
Types of electroplating: single metal electroplating (as above), alloy electroplating, composite electroplating, chemical plating. Vacuum coating and ion sputtering are also called electroplating by many people. Such as aluminum oxidation, blackening/bluing, chemical polishing, electrochemical polishing, passivation, etc., are also classified as electroplating.
