每一种机械总是存在着。相对运动的偶合表面”,而机械的质量和寿命往往取决于这些“偶合表面”的摩擦和磨损性能。从摩擦学的观点看,材料和润滑剂的选择在工程设计中占重要地位,其目的是要控制摩擦、减少磨损。选择材料,主要是根据工况确定材料的强度、硬度、耐磨性、耐腐蚀性和尺寸稳定性等技术要求;要注意经济效果,选择能满足技术要求的最便宜的材料:要考虑材料的工艺性,确定合适的热处理工艺,来改善材料的机械性能.
Every kind of machinery is always there. Relatively moving coupling surfaces, “while the quality and longevity of the machine often depends on the friction and wear properties of these” coupling surfaces. "From a tribological point of view, the choice of materials and lubricants is of central importance to engineering design, and its purpose Is to control the friction and reduce wear.Selected materials, mainly based on working conditions to determine the material strength, hardness, wear resistance, corrosion resistance and dimensional stability and other technical requirements; pay attention to economic effects, choose to meet the technical requirements of the most Cheap materials: to consider the material processability, determine the appropriate heat treatment process to improve the mechanical properties of the material.
