| 摘 要： | 对32Cr2MoV进行了复合镀膜处理以及滑动摩擦试验。结果表明,离子镀膜虽然加大了经过机械抛光的离子氮化试样的表面粗糙度,但在相同的实验条件下,离子镀TiN后,其摩擦力、磨损量、磨痕宽度、摩擦系数均有所减小,并且其承受的摩擦载荷大大提高。表面磨痕观察表明,二者为磨粒磨损,且离子氮化+离子镀TiN试样的磨痕沟槽较浅,因此经复合处理后的32Cr2MoV在滑动摩擦条件下也具有较好的耐磨性。

| Abstract: | The sliding friction experiment of duplex-coated TiN 32Cr2MoV was investigated.The results show that friction force,wear capacity,friction coefficient,wear mark widths of duplex-coated TiN 32Cr2MoV are lower than that of nitrided 32Cr2MoV,which make Duplex-coated TiN 32Cr2MoV carry higher friction loads,while the deposition of TiN coating increase the roughness of the nitrided 32Cr2MoV being mechanical polished.The observation of surface wear mark reveals that both duplex coated 32Cr2MoV and nitriede 32Cr2MoV are grinding abrasion and groove of wear marks of duplex coated 32Cr2MoV is more shallower,which indicate that deposition of TiN onto nitrided 32Cr2MoV supply better wear resistance. |
