摘要

This research systematically explores the corrosion and tribological performance of graphene oxide (GO)-reinforced Al5052 alloy fabricated through accumulative roll bonding (ARB). Four alloy variants were analysed: as-received Al5052 (5052AR), ARB-processed alloy (5052/5pass), and GO-reinforced alloys with 0.1 wt.% (5G01/5) and 0.2 wt.% (5G02/5) GO. Potentiodynamic polarization indicated a substantial corrosion resistance improvement, with a 74% reduction in corrosion rate for 5G02/5 compared to 5052AR. Weight-loss assessments under acidic, alkaline (48 h), saline, and neutral (30 days) conditions showed significantly lower weight losses (60–70%) for GO-reinforced alloys. SEM and EDS analyses confirmed stable, dense passive films reducing localized corrosion. Tribological evaluations revealed friction and wear reductions of approximately 55% and 60%, respectively, highlighting GO-reinforced Al5052’s suitability for demanding engineering applications.
