Corrosion characteristics of zinc coated SS304 stainless steel

Stainless Steel 304 (SS 304) is considered as one the most important material in the field of Bio-medical and various other applications. The corrosion properties must be looked into all these materials that con- stitute the medical applications. In the present investigation we determine the corrosion characteristics of zinc coated SS 304 steel in various acidic, neutral and basic solutions at different molar concentrations of chloride and different PH in alkaline solutions. The corrosion characteristics were then compared with uncoated SS 304 Steel. The corrosion resistance of the substance was tested by potentiodynamic polar- ization test. The various acidic, basic and neutral solutions tested are NaCl, NaOH, HCl in various molar concentrations that is at 1 M, 0.1 M, 0.01 M. Results indicate that Zinc coated SS304 Steel showed higher corrosion resistance when compared with uncoated steel indicating that coating was necessary to reduce the oxidation of the iron in SS304 Steel and a passive layer formed can increase its corrosion rate significantly.
