Mechanical Zinc Coating

The coating has a density of about 0 45 oz ft 2 mil compared to the hot dip galvanized coating density of about 0 6 oz ft 2 mil.

Mechanical zinc coating. Mechanical plating also known as peen plating mechanical deposition or impact plating is a plating process that imparts the coating by cold welding fine metal particles to a workpiece. It is essentially a cold welding concept that applies the coating using mechanical energy at room temperature without giving any lasting hydrogen embrittlement. The coating upon micro cross section appears to consist of flattened particles of zinc loosely bonded together. Mechanical zinc process uses kinetic impact energy of impact media along with special chemicals and zinc alloy powder to create an adherent uniform highly corrosion.

Mechanical zinc is an excellent coating method that imparts a superb metal surface finish on ferrous metal components for providing long term corrosion protection. Almac coatings are combinations of aluminium and zinc which give substantially increased corrosion resistance compared with zinc. The components to be coated are placed into a tumbling barrel containing. The hot dip coating has over 30 more zinc per unit volume than the mechanical coating.

The corrosion protection is directly related to the amount of zinc in the coating. Mechanical plating can be used to apply zinc tin or aluminium coatings either singly or in combination. Mechanical zinc is an excellent coating method that imparts a superb metal surface finish on ferrous metal components for providing long term corrosion protection. It is commonly used to overcome hydrogen embrittlement problems.

At chem plate industries we offer a wide range of mechanical plating processes including standard zinc plating and galvanizing silver plating zinc aluminum coatings tin coatings and our cp 2000 process which is a quad metal coating with salt spray in excess of 2500 hours. Galvanization or galvanizing also spelled galvanisation or galvanising is the process of applying a protective zinc coating to steel or iron to prevent rusting the most common method is hot dip galvanizing in which the parts are submerged in a bath of molten hot zinc. Mechanical galvanizing and plating specifications thicknesses. Cip is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals.

The coating density is approximately 0 45 oz ft 2 mil compared to the hot dip galvanized coating density of about 0 6 oz ft 2 mil. Mechanical zinc process uses kinetic impact energy of impact media along with special chemicals and zinc alloy powder to create an adherent uniform highly corrosion. The hot dip coating has over 30 more zinc per unit volume than the mechanical coating. They are more ductile than zinc and are very advantageous when used in contact with aluminium.
