摘　　要：研制了磨损自补偿润滑添加剂ES12 ,并对 4 5钢 4 5钢摩擦副及 4 5钢 锡青铜摩擦副的磨损自补偿效应和摩擦学效应进行了研究。结果表明 ,当载荷增加 1.2 5倍 ,N4 6液压油润滑的钢 钢副磨损增大了 1.73倍 ,N4 6 ES12润滑的钢 钢副由负磨损转为微量正值 ,为 0 .0 4mg。当行程增加 3.98倍 ,N4 6液压油润滑的钢 钢副磨损增大了 2 .16倍 ,N4 6 ES12润滑的钢 钢副的磨损由 0 .0 1mg降低到 - 0 .0 7mg。N4 6 ES12润滑的钢 铜副在不同载荷和行程内为负磨损。N4 6 ES12润滑钢 钢副和润滑钢 铜副的PB值都为 1472N。Additive ES12 was developed as wear-self-compensation, and the self-compensation effects and tribological effects of steel 45-steel 45 rubbing pairs and steel- 45-tin bronze rubbing pairs were studied. The results showed that while load increased 1.25 times, the abrasive mass of steel 45-steel 45 pairs increased 1.73 times with N46 lubrication but abrasion increased a litter from negative to 0.04 mg for N46-ES12. While travel increased 3.98 times, abrasive mass of steel 45-steel 45 pairs increased 2.16 times for N46 and little decreased from 0.01 mg to -0.07 mg for N46-ES12. It was negative for steel-bronze with N46-ES12 under different load and rubbing time. The values of P-B were both 1 472 N for steel-steel pairs and steel-bronze pairs with N46-ES12.
