WebThe prepared PALF-based polyester composites were examined for different properties (impact, flexural, tensile strength, and wear rate). Coefficient of friction and wear studies are performed on the prepared composites subjected to different loads (10, 20, and 30 N) via a pin on disc test rig. WebFeb 2, 2024 · Experimental findings showed that the addition of 0.5 wt.% GrO was effective in reducing the friction coefficient of polyester coating. Meanwhile, under the same sliding conditions, the wear results revealed that the polyester coating filled with 1 wt.% GrO has better antiwear ability compared to those filled with 0.5 and 0.75 wt.% GrO.
