Abstract:
Microarc oxidation (MAO) treatment produces a thick Al 2 O 3 coating on the 15SiC p /2024 aluminum matrix composite. After pretreatment of Ti ion implantation, a thin diamond-like carbon film (DLC) was deposited on the top of polished Al 2 O 3 coating 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 duplex Al 2 O 3 /DLC multiplayer coating were investigated by Raman spectroscopy, scanning electron microscopy (SEM) and SRV ball-on-disk friction tester. It is found that the duplex Al 2 O 3 /DLC coating had good adhesion and a low friction coefficient of less than 0.07. As compared to a single Al 2 O 3 or DLC coating, the duplex Al 2 O 3 /DLC coating on aluminum matrix composite exhibited a better wear resistance against ZrO 2 ball under dry sliding, because the Al 2 O 3 coating as an intermediate layer improved load support for the top DLC coating on 15SiC p /2024 composite substrate, meanwhile the top DLC coating displayed low friction coefficient.
