Coating

Hard anodizing

Process Surface coating process where an aluminum workpiece that acts as the anode is subjected to high voltage and is oxidized in a cooled acidic solution which creates a corrosion-resistant and durable surface.

Hexavalent hard chromium

Process Surface coating process where the workpiece through an anode-cathode reaction is coated with hexavalent chromium.

Hot Galvanizing

Process Galvanized surface coating process where the workpiece is dipped into a bath of molten zinc to form a surface.

Iron phosphating

Process Galvanized coating treatment where the workpiece through the conversion coating reacts with the added solution and so that a layer of iron is formed on the workpiece surface.

Multi-layer nickel plating

Process Surface coating process where the workpiece through two subsequent anode-cathode reactions is coated with two or more layers of nickel.

Plasma spraying

Process Surface coating method in which plasma is used for melting and spraying a powder onto the workpiece that is coated.
