在27SiMn基体上制备一种新型的Ni-P-Ti3AlC2化学复合镀层,利用SEM,XRD对镀层形貌和物相进行表征,利用显微硬度计和磨粒磨损实验机分别对复合镀层的硬度和耐磨性进行研究.结果表明:Ni-P-Ti3AlC2复合镀层的沉积方式为颗粒堆积,相对于Ni-P二元镀层表面比较粗糙;复合镀层为非晶态结构,其硬度和耐磨性比二元镀层显著提高.
在27SiMn基體上製備一種新型的Ni-P-Ti3AlC2化學複閤鍍層,利用SEM,XRD對鍍層形貌和物相進行錶徵,利用顯微硬度計和磨粒磨損實驗機分彆對複閤鍍層的硬度和耐磨性進行研究.結果錶明:Ni-P-Ti3AlC2複閤鍍層的沉積方式為顆粒堆積,相對于Ni-P二元鍍層錶麵比較粗糙;複閤鍍層為非晶態結構,其硬度和耐磨性比二元鍍層顯著提高.

A novel Ni?P?Ti3AlC2 electroless composite plating was prepared on 27SiMn alloy. The surface morphology and phase analysis of the plating were characterized with SEM and XRD,meanwhile,the hardness and wear resistance of the plating were analyzed by microhardness tester and abrasive wear machine,respectively. The results show that the depositional style of Ni?P?Ti3AlC2 plating is the particle packing,and the surface of composite plating becames more coarser compared to that of electroless Ni?P plating;the XRD results reveal that the composite deposits have a typical amorphous structure. The microhardness and wear resistance of the composite plating are superior to that of Ni?P plating.
