- Conversion film is a metal compound film produced by chemical or electrochemical treatment of metal surface in material protection technology.
- The most commonly used in machinery manufacturing are aluminum anodized film, phosphate film on steel, chromate film on aluminum, zinc, cadmium and blue film on steel. In addition, there is also an oxalate film on ordinary steel, which can be used as a pre-treatment layer during coating. It can effectively protect the substrate from sulfite corrosion; the conversion film on stainless steel and other high-alloy steels containing nickel, chromium and other elements is conducive to increasing the drawing speed and acceleration during cold deformation processing (drawing, drawing, extrusion). Large cross-section shrinkage and reduced tool wear. There are also many ways to protect magnesium products using conversion films.
