Abstract

Microarc oxidation (MAO) treatment produces a thickAl2O3coating on the 15SiCp/2024 aluminum matrix composite. After pretreatment ofTiion implantation, a thin diamond-like carbon film (DLC) was deposited on the top of polishedAl2O3coating by a pulsed filtered cathodic vacuum arc (FCVA) deposition system with a metal vapor vacuum arc (MEVVA) source. The morphology and tribological properties of the duplexAl2O3/DLC multiplayer coating were investigated by Raman spectroscopy, scanning electron microscopy (SEM) and SRV ball-on-disk friction tester. It is found that the duplexAl2O3/DLC coating had good adhesion and a low friction coefficient of less than 0.07. As compared to a singleAl2O3or DLC coating, the duplexAl2O3/DLC coating on aluminum matrix composite exhibited a better wear resistance againstZrO2ball under dry sliding, because theAl2O3coating as an intermediate layer improved load support for the top DLC coating on 15SiCp/2024 composite substrate, meanwhile the top DLC coating displayed low friction coefficient.
