Surface finish and cleaning process, usually used for stainless steel whereby, by means of electrical currents, any impurities which may cause corrosion are removed. They may also be used with copper, brass or aluminium parts.
In this case the steel parts are placed in a saline/zinc solution which, through electrolysis, makes the zinc particles be deposited throughout the surface of the part, in order to protect it against corrosion.
This is a coating comprising zinc and aluminium flakes in an inorganic binder. It is Chromium free. This is a good solution, particularly for threaded parts as it is about 10 times thinner than hot-dip galvanized coating, and nut oversizing might not be required.
Hot dip galvanizing
This is a surface treatment which helps to protect the part from corrosion. In this process the part is placed into a bath of molten zinc at a temperature of around 450ºC so that the particles of pure zinc will be totally adhered to the part.
