    phosphating

    The process in which steel parts are immersed in phosphate solution to deposit on the surface and form crystalline phosphate conversion film insoluble in water is called phosphating treatment. The commonly used phosphating solution is ferromangangate phosphate and zinc phosphate solution. The thickness of phosphating film after phosphating treatment is generally 5 ~ 15mm, and its corrosion resistance is 2 ~ 10 times that of the blue treatment. The phosphating film has strong binding force with the matrix, good corrosion resistance and high insulation performance, and has good corrosion resistance in the atmosphere, oil, benzene and toluene and other media, and has excellent absorption ability to oil, wax, pigment and paint, suitable for the paint base. However, the strength and hardness of the phosphating film itself is low, with a certain degree of brittleness, when the steel deformation is large, easy to appear fine cracks, not impact resistance, poor corrosion resistance in acid, alkali, sea water and water vapor. After the phosphating treatment, the corrosion resistance can be improved greatly.

    The equipment needed for phosphating treatment is simple, easy to operate, low cost and high production efficiency. In general mechanical equipment can be used as steel parts of the protective layer can also be used as a variety of weapons lubrication layer and protective layer.
