Friction and Wear Characteristics of Micro-Arc Oxidation Coating for Light Weight, Wear Resistant, Powertrain Component Application

An extremely tough alumina based ceramic coating produced by a modified anodizing process developed at Moscow Aviation Institute has been evaluated for light weight, wear resistant component applications in automotive powertrain. The process details and test results from comparative evaluation of friction and wear properties for cylinder bore application, referenced to cast iron baseline, are presented and discussed.
