▎ 摘　　要

Ultra-high molecular weight polyethylene nanocomposite coatings reinforced with 1 wt.% graphene nanoplatelets were deposited on aluminum substrates. Sliding wear tests with a pin-on-disc configuration were conducted at different temperatures (25(o)C, 75(o)C, 90(o)C, 115(o)C, and 125(o)C) to evaluate the wear behavior of the coating at elevated temperatures. The ultra-high molecular weight polyethylene/1 wt.% graphene nanoplatelets nanocomposite coating showed an outstanding performance by passing the wear test without failing even until temperatures of 115(o)C as compared to the pure ultra-high molecular weight polyethylene coating which failed at a much lower temperature of 75(o)C, indicating an improvement in the operating temperature range of ultra-high molecular weight polyethylene by at least 44%.
