对新型高强度、高耐磨铝青铜合金(代号HSWAB)在润滑条件下的摩擦性能进行了分析。结果表明,HSWAB合金的高耐磨性主要取决于其显微组织,在润滑条件下磨损失效形式主要为磨粒磨损与粘着磨损。由于HSWAB合金基体强度高,强化相呈弥散分布,在润滑摩擦过程中形成高强度的骨架和光滑的支撑面,磨粒细小、圆整、数量少;在润滑及骨架与光滑面的支撑作用下,粘着磨损不能进一步发展,并且合金在摩擦过程中无氧化与裂纹现象产生。
The tribological properties of the new high-strength, high-wear aluminum bronze alloy (code HSWAB) under lubrication conditions were analyzed. The results show that the high wear resistance of HSWAB alloy mainly depends on its microstructure, and the main wear failure modes of HSWAB alloy are abrasive wear and adhesive wear. Due to the high strength of HSWAB alloy matrix, the reinforcing phase is dispersed, forming high strength skeleton and smooth support surface in the process of lubrication and friction. The abrasive particles are small, round and small in number. Under the support of lubrication and skeleton and smooth surface , Adhesive wear can not be further developed, and the alloy in the friction process without oxidation and cracking phenomenon.
