摘要: 本文研究了钢在平面滑动摩擦过程中产生的“白层”,以及摩擦力大小、摩擦速度、冷却条件和原始金相组织等因素对摩擦白层的厚度、硬度和表面成分变化的影响。研究结果表明,55SiMnMo钢正火态金组织在压力1.47MPa、磨合程度达80%面积、转速2000~2100r/min和油冷条件下,能获得致密的厚度适当的白层。

Abstract: Thickness, hardness and composition changes of “white lager” formed on the surface of steel after friction test by plane-sliding were influenced by many factors, such as friction force and velocity, cooling conation and original microstructures. It had been found the “white layer” formed on the surface of 55SiMaMe steel after normalizing exhibited dense microstructure and a suitable thickness under the operation consisting of pressure with 1.47 Mpa, contacted area up to 80%, relational speed an 2000 to 2100r/min and oil cooling.
