| 摘 要： | 用环块磨损试验机对铬电极电火花熔涂层及淬火低温回火态45^#钢的边界润滑滑动磨损特性进行了研究。结果表明，轻载低速条件下，熔涂层与45^#钢的边界润滑滑动磨损机制以犁沟划伤为主，熔涂层的磨损量与45^#钢的相当；重载高速条件下，熔涂层的磨损机理以粘着磨损和磨料磨损为主，而45^#钢的磨损机理以点蚀剥落为主：熔涂层的磨损量远比45^#钢的人。

| Abstract: | The sliding wear characteristics under boundary lubrication of the coating electrospark-deposited on 45 steel with Cr anode was studied with a ring-on-block tester.The results show that at low sliding speed and small load,the main wear mechanism of the coating and 45 steel is scratching,and the width of the wear scar of the coating is approximately equal to that of 45 steel,and at high sliding speed and large load,the main wear mechanism of the coating is abrasive and adhesive delamination while the main wear mechanism of the 45 steel is pitting,and the width of the wear scar of the coating is larger than that of 45 steel. |
