Effect of binary Al-Ni alloy on the rate of abrasive wear of ultra-high molecular weight polyethylene

The paper investigates the influence of the content of Al-Ni alloy quenched from the molten state on the abrasive wear rate of ultra-high-molecular-weight polyethylene on rigidly attached abrasive particles. Studies have shown that the addition of 5–30 mass% of the quenched aluminum alloy to ultra-high-molecular-weight polyethylene reduces the rate of abrasive wear by ~50%. The improvement of this indicator is due to the high values of microhardness, dislocations density, and microstresses of rapidly quenched Al-Ni alloys.
