Process Surface coating process where the workpiece through an anode-cathode reaction in an organic or inorganic solution is coated with a layer which is semi-glossy and resembles satin.
Process Surface coating process where an aluminum workpiece that acts as the anode is subjected to voltage and is oxidized in an acidic solution which creates a corrosion-resistant and durable surface.
Process Surface coating operations in which a workpiece is rotated while liquid paint is dropped and spread over its surface to create a thin surface coating.
