摘要
用强烈拉伸塑性变形法制备纳米结构高强度珠光体钢丝,将其与聚氨酯复合制备复合材料,并研究了该复合材料的三体磨料磨损性能。试验结果表明:纳米结构高强度钢丝增强聚氨酯复合材料具有优良的耐磨料磨损性能;丝材的磨损机理主要是显微切削、微观犁沟以及剪切断裂剥落,聚氨酯基体磨损形式则以塑性堆积、犁削、粘着和疲劳裂纹为主。
Under heavily drawn plastic deformation, we made nano-structured high strength pearlitic steel reinforced polymer urethanes composites, and investigated the composites＇ three-body abrasive wear mechanism. The results show that the composites has an excelent abrisive-wear-risistance ability； the mechanisms of the wire include micro-cutting, micro-plughing and spalling, and that of the matrix are plastic stacks, cut-ploughing, adhesion and fatigue cracks.
