The corrosion resistance of AlSI 316L stainless steel with a thermally sprayed alumina coating has been studied in physiological media using a five way experimental design arrangement with one observation per cell. The parameters studied were the corrosion potential and intensity and the factors considered were passivation, the intermediate coating, type of alumina, particle size, and holding time in the bath. The corrosion resistance of the material tested is reduced markedly when an intermediate sprayed coating is applied between the base metal and the ceramic layer.
