Abstract

An Ni44 Fe32Cr11P8B5 (at.%) alloy was sputter deposited on to water cooled 304 stainless steel substrates. Electrochemical testing was performed in 0.1N H2So4 with and without the addition of O.06N NaCI. The surface layers of specimens polarized into the active and passive regions of the anodic polarization curves were analyzed using x-ray photoelectron spectroscopy (XPS) to check for preferential dissolution and possible segregation of the constituent elements. A significant improvement in the overall corrosion behaviour of 304 stainless steel was observed due to the sputter deposited layer.
