 These are surface treatments for metallic components which impart super hydrophobicity, self-cleaning, antifouling, deicing and corrosion resistance to alloys, including brasses, irons, aluminum alloys and Hastelloy used in water industry and will be of interest to other industries including food processing and aircraft industry.Surfaces of mild steel castings can be enriched by nickel, chromium and other elements during low cost conventional casting in foundries.The surface alloyed castings are lower in cost compared to through section castings of alloys like 316 stainless steel and super duplex steel, and the hardness and corrosion resistance of surface alloyed metal steel castings is similar to stainless steel















Automakers are being subjected to increasingly strict fuel economy requirements, while consumers are demanding improved interior comforts and advanced electronic systems for safety, navigation, and entertainment, all of which add otherwise unnecessary weight.
