In this study, a plasma electrolytic oxidation process is used in order to produce a layer of oxide on aluminum silicon alloy 316. A pulsed dc power mode with frequencies up to 2000 Hz is selected with current density variations from 0.06 to 1.4 A/cm2. Surface morphology (roughness), microstructure (grain size) and other properties of the plasma induced layer such as hardness and toughness are studied. Various coating conditions are compared based on treatment time, wear scar and coefficient of friction. These are critical coating properties for automotive engine block applications. The study is concluded by selecting the best coating condition with the optimized thickness.
