化学镀高磷Ni—P镀层的摩擦磨损性能王政君,赵永武(江南大学机械工程学院,江苏无锡214122)摘要:制备了一种高磷化学镀镍层并研究其表面形貌;讨论了其在不同温度热处理后的摩擦磨损性能,,Ni—P镀层的耐磨性明显优于45钢,且经500℃热处理后硬度最高,耐磨性最好,—P镀层的摩擦磨损机理进行了初步探讨,认为200℃热处理后主要表现为粘着磨损,500℃:化学镀;高磷镀层;耐磨性中图分类号::AStudyontheFrictionalandWearPropertiesofHigh_PElectrolessNi-PCoatingWANGZheng—jun。ZHAOYong—WU。(SchoolofMechanicalEngineering,SouthernYangtzeUniversity,Wuxi214122,China)Abstract:Theresearchonthefrictionalandwearpropertiesofhigh—PelectrolessNi—,themorphologyofNi—,thefrictionalcoefficientsandwearratesofNi—Pcoated45steelwhichexperiencesdifferentheat———Pcoated45steelareobtainedwhenitisheat—treatedat500℃.Finally。thepresentresearchmakesapreliminaryexplorationofthepossiblewearmechanismsofNi——Pcoatingheat—treatedat200℃whilebothabrasivewearandadhesivewearcoexistforNi—Pcoatingheat—treatedat500℃.Keywords:electrolessplating;high—Pcoating;wearresistance化学镀Ni—P镀层是应用非常广泛的功能性镀层,它具有优异的性能且均镀能力强,,更优异的耐腐蚀性口。和突出的非磁性能[4]
