【摘要】 采用SEM、X射线衍射(XRD)和显微硬度计研究和分析索道钢丝绳外层断丝表面白亮腐蚀层的硬度、结构和形成原因,白亮腐蚀层内的显微硬度最高达882 HV,结果表明:表层区域内的纳米索氏体-马氏体的形成是由于钢丝绳外层丝在承受弯曲交变载荷和摩擦力过程中严重塑性变形和冷加工诱发相变而导致的,这也是造成基体加工硬化区与纳米索氏体-马氏体区之间存在显微硬度差异的原因。更多还原

【Abstract】 The hardness,structure and formation cause of white corrosion layer in cableway wire rope outer layer fracture wire wear surface layer were researched and analyzed by adopting SEM,XRD and microhardness tester.The highest microhardness of white corrosion layer reached 882 HV.Results show that the formation of nano sorbite-martensite in surface region is caused by wire rope outer layer wire serious plastic deformation and cold induced phase change in the process of sustaining bending alternating load and friction force.This is another reason of microhardness difference existing between matrix process hardness region and nano sorbite-martensite region.更多还原
