Abstract:

Following a discussion of the shortcomings of the hot method of coating iron and steel with a phosphate solution for protection against corrosion, the author describes a method of cold phosphatization involving the use of zinc dihydrophosphate, fluorine compounds, and accelerators to decrease free acidity and promote depolarization of the hydrogen liberated by phosphatization. The high corrosion resistance and strength of the phosphate coatings were demonstrated in laboratory and industrial tests. Author
