Experimental Investigation on Tribological Behaviour of Various Processes of Anodized Coated Piston for Engine Application

In the automobile sector, pistons are anodized on crown, ring grooves, and also skirts to improve its wear resistance corrosion properties. this work, we have carried out crown anodizing along with skirt simultaneously study of samples. The surfaces three different processes such as soft anodizing, hard microarc oxidation (MAO) or well known plasma arc (PAO). All differ in their respective procedures. hardness value microstructure all samples were tested find values effect coatings testing, piston rubbed cast iron denote based weight loss per unit time. Reciprocating testing is every sample for value.
