摘要：Surface modification is a generic term now applied to a large field of diverse technologies that can begainfully harnessed to achieve increased reliability and enhanced performance of industrial components. The increasingutility and industrial adoption of surface engineering is a consequence of the significant recent advances in the field.Among the various coating techniques to enhance the surface properties of Al2O3 coated mild steel we have adopted thethermal coating technique of Plasma spray process. The Thermal spraying is the coating deposition technology inwhich solid feedstock in form of powder, wire, or rods is introduced to a hot gas, flame, or plasma jet to form liquiddroplets which are accelerated toward a substrate. In this paper we have discussed the surface morphology of Al2O3coated over mild steel using various surface characterization techniques such as Scanning Electron Microscope andAtomic Force microscope.
