摘　　要：船闸易损件具有高耐磨性是船闸正常工作的一个关键因素。通过对CuN iCoBe材料在水润滑和锂基脂+3%MoS2润滑条件下的试验,论证了HB200和HB270两种热处理的CuN iCoBe材料作为船闸耐磨材料的可能。在销盘实验机上测试了两种热处理材料的耐磨性。试验表明,材料在水润滑条件下耐磨性很差,但仍好于其它同等实验条件下很多材料的耐磨性,HB200和HB270材料的平均磨损率分别为7.3×10-6g/m和3.9×10-6g/m;在锂基脂+3%MoS2润滑条件下耐磨性很好,HB200和HB270材料的平均磨损率分别为1.46×10-7g/m和2.05×10-7g/m。通过SEM分析磨损表面发现在水润滑条件下的磨损机理是塑性变形,而在锂基脂+3%MoS2润滑条件下,材料的磨损机理是轻微犁沟作用。The anti-wear performance of easily worn components of a shiplock is an important factor for its normal operation. The wear performance of CuNiCoBe with HB200 and HB270 heat treatment is tested under water lubrication and lithium grease ＋ 3% MoSs lubrication in order to prove the possibility of using CuNiCoBe as shiplock material. The wear performance is tested on a pin-on-disc tester. The test proves that wear performance of CuNiCoBe under water lubrication is bad, with average wear rate being 7.3 × 10^-6 g/m and 3.9 × 10^-6 g/m for HB200 and HB270 heat treatment material respectively, Whereas under lithium grease ＋3% MoS2 lubrication the wear rate is 1.46 10^-7 g/m and 2.05 × 10^-7 g/m for HB200 and HB270 heat treatment material respectively. SEM analysis inaicates that under water lubrication, the wear mechanism is plastic deformation, while under lithium nism has slight plough effect. grease ＋ 3% MoSs lubrication, the wear mechanism has slight plough effect.
