Thin film coating are formed on the enginneering materials to improve their physical and mechanical properties these coating are used mainly in different fields of industrial application and in these respect many research projects conducted to improved their properties.In this research,therefore,the formation of Al-Pt(Aluminum/Platinum)alloys coatings on nickel based super alloys has been studied.Sputtering-ion beam technique under Argon plasma and subsequent heat treatment is been used to fabricate these coating.Ion implantation is applied the Aluminum-Platinum alloys coatings.The main goal of this work is increasing erosion and consequently erosion-corrosion resistance of these coating.Scan Electron Microscope,Glow discharge Spectrometers and X-Ray Diffraction techniques is used to investigate the structure of fabricated coatings.These results correlates with other investigations and these method can be presented as a industrial method for fabrication of these coating.Ion implantation improved these properties but the results not very appreciable.Details will discus in full paper.
