Tribological Properties of the Ceramic Coatings Prepared by Plasma Electrolytic Oxidation (PEO) on the Al6061 Alloy

Abstract:

The ceramic coatings were prepared on the T6-tempered Al6061 alloy substrate under a hybrid voltage by PEO treatment in 5-30 min in a phosphate electrolyte. The X-Ray diffraction (XRD) and scanning electron microscopy (SEM) were used to investigate the coating microstructures. With increasing the PEO treating time, the different compositions of coatings eliminate the sharp slope of the microhardness profile. The coatings PEO-treated in 30min presents excellent abrasive resistance property.
