Phosphatization

WebPhosphating (also phosphatization) is a chemical process in which coatings are generated on a pure metal (normally steel) surface. Coatings generated by phosphating are electrically non-conductive and therefore reduce the corrosion current value. The coatings bond well with the base metal and are not water- or chemically soluble. WebThe effects of phosphatization on individual trace metal concentrations, speciation, and phase associations in FeMn crusts remain poorly understood yet may be important to metal enrichment mechanisms, paleoceanography, and extractive metallurgy.
