22、steel, cadmium and their alloys) either as an end finish or as an intermediate layer for other coatings. They are intended to a) impart corrosion resistance, b) improve adhesion to paints and other organic finishes, c) facilitate cold-forming operations, such as wire drawing, tube drawing and extrus

23、ion, and d) modify surface frictional properties so as to facilitate sliding. Phosphate conversion coatings are produced by treatment with solutions, the main constituents of which are the appropriate dihydrogen orthophosphates. These coatings are applied principally to ferrous materials, aluminium,

24、 zinc and cadmium and differ in coating mass per unit area and apparent density, depending on a) the construction material and surface condition of the components, b) previous mechanical and chemical treatment of the components, and c) processing conditions for phosphating. All phosphate conversion

25、coatings are more or less porous but can be sealed substantially by subsequent sealing processes.
