摘　　要：为探究银镀层对基体的保护作用,利用成品动触头触片和自制镀银铜片开展性能研究和摩擦磨损试验,结果表明:成品触片的银镀层在低频、中等振幅的摩擦条件下具有较好的耐磨性,可以对铜基体起到有效防护作用,但其厚度波动较大、表面粗糙度较高,将会影响到实际应用中的耐磨性能;自制银镀层具有更低的表面粗糙度,与成品银镀层相比,在试验过程中的摩擦系数更小,具备更高的耐磨性;较厚的银镀层在相同的摩擦条件下将承受更大的摩擦力,不利于银镀层对基体的保护作用。In order to explore the protective effect of silver coating on the moving contact of tulip contact,the performance research and tribological test were carried out using the finished moving contact and the self-made silver coating based on copper substrate.The results show that the finished silver coating of the finished contact piece has great wear resistance and can effectively protect the copper substrate under the friction conditions of low frequency and medium amplitude.However,its large thickness fluctuation and high surface roughness will affect the wear resistance in practical application.The self-made silver coating has lower surface roughness,lower friction coefficient and higher wear resistance than the finished silver coating during the tribological test.Thicker silver coating will bear greater friction under the same friction condition,which is not conducive to the protection of silver coating on the substrate.
