Mechanical Zinc Coating
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.
Mechanical zinc coating. It is essentially a cold welding concept that applies the coating using mechanical energy at room temperature without giving any lasting hydrogen embrittlement. 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. 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. Cip is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals.
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. The hot dip coating has over 30 more zinc per unit volume than the mechanical 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. The corrosion protection is directly related to the amount of zinc in the coating. Inverplex is a mixed coating of zinc and tin that has better conductivity and corrosion resistance than zinc.
Mechanical galvanizing and plating specifications thicknesses. We also work with both type i as coated without supplementary treatment and type ii with chromate conversion treatment b695 specifications for special processing needs. Mechanical galvanization is the same process but applies to coatings that are thicker than 0 001 in 0 025 mm. 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.
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 is an excellent coating method that imparts a superb metal surface finish on ferrous metal components for providing long term corrosion protection. The coating upon micro cross section appears to consist of flattened particles of zinc loosely bonded together. Almac coatings are combinations of aluminium and zinc which give substantially increased corrosion resistance compared with zinc.
