Phosphatization
WebOct 1, 2024 · The phosphatization layer that plays a key role on the excellent anticorrosion properties obtained (measured by EIS analysis of coated sample immersed in 3.5 wt% NaCl solution and in an aggressive salt spray chamber), strongly depends on the humidity at which the waterborne dispersion is applied; at relative humidity above 60%, optimum ... 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.
