本文扼要地介绍了化学镀镍技术的特点。针对发动机实际工况 ,进行快速模拟磨损对比试验 ,建立了强化材料的磨损规律数学模型 ,并绘制了负荷———速度———磨损量三维曲面图。对化学镀镍磷合金的耐磨性进行较全面的评价 ,初步探讨了化学镀镍用于强化进口发动机气缸的可行性。 This article briefly introduced the characteristics of electroless nickel plating technology. According to the actual working conditions of the engine, a rapid simulated wear comparative test was carried out, and a mathematical model of the wear law of the strengthened material was established. The three-dimensional curved surface diagram of load --- speed --- wear was drawn. The wear resistance of electroless nickel-phosphorus alloy is evaluated comprehensively, and the feasibility of electroless nickel plating for strengthening imported engine cylinder is discussed.
