【摘要】 随着作为舰船、机车主要动力的柴油机不断向大功率、高负荷、高增压、低油耗和轻自重的方向发展，对柴油机零件如气缸、凸轮、传动齿轮等摩擦副的机械性能、工作可靠性等提出了更高的要求．因此，为满足这些要求而进行的材料选择、热处理工艺研究，特别是表面强化热处理工艺研究具有重要意义。更多还原

【Abstract】 With the diesel engines used as the main power of ships and locomotives continuouslyprogressing towards big power, high load, high-degree supercharging, low fuel consumption and lightself weight even higher demand has been set on the mechanical performance, operating reliability andetc. of their frictional paired parts, such as the cylinder liner, the camshaft the transmission gear andothers. It is significant hlerefore, to carry out investigations in msterial selection and heat treamentttechnology, particalarly in surface strengthening heat treatheent.更多还原
