金属成型拉拔模、精整模和落料模、塑料加工挤压工具和注塑模、金属切削工具以及仪表、纺织和电子工业中的导向件和滑动件等都是承受高磨损负荷的工件。这种负荷的特点是一对摩擦副材料在确定的压力和温度以及化学环境条件下的相对运动。应力、材料结构和表面性能所形成的材料特性表现为表面材料的磨耗、摩擦副的焊合和在表面产生的各种损坏机理。防止工件过早损坏对国民经济的意义很大。为此要尽力改善材质来提高其使用寿命。对那些不承受冲击和撞击负荷,而公差范围又很小的构件,涂复金属碳化
Metal forming dies, finishing and blanking dies, plastic processing extrusion tools and injection molds, metal cutting tools and instrumentation, textile and electronics industries, such as the guide and the slider are all subject to high wear and tear of the workpiece. This load is characterized by the relative motion of a pair of friction materials at a defined pressure and temperature as well as under chemical and environmental conditions. The material properties formed by stress, material structure and surface properties are manifested by wear of the surface material, welding of the friction pair and various damage mechanisms occurring on the surface. Preventing premature workpiece damage is of great significance to the national economy. To this end, we should try our best to improve the material to improve its service life. For those who do not withstand the impact and impact load, and the tolerance range is very small components, painted metal carbonization
