Tribological Behavior of Plasma Electrolyte Oxidation Coating on Al 319 Aluminum Alloy 2012-01-0165

The need for green energy and less fuel consumption is a non-stop demand for researchers and academia from the industry and the automotive market. Several solutions were found and some are being practiced and commercialized. Plasma Electrolyte Oxidation (PEO) technique is a fast growing approach to resolve the weight load in automotive industry by creating a thin layer of a ceramic coating on lighter alloys such as aluminum for different parts like engine blocks. Of course in a hot and corrosive environment such as an engine, the main concern would be corrosion and wear effects on the engine. The goal of this research is to study the effect of different factors such as solution type, power input variations and coating thickness on wear resistance of aluminum Al 319.
