对摩擦部件材料的要求 现代机器制造业和运输业的发展是与摩擦部件的运转速度和载荷容量的提高联系在一起的。对抗摩材料的要求是由它的工作条件决定的,并在广阔的范围内变化着。但是,存在着一系列对所有抗摩材料都必须共同具备的要求,这些共同的要求就是:尽可能低的摩擦系数和高的耐磨性;最优化的整体和表面强度,这种强度使表面层的高强度与能够有效磨合相结合;足够高的韧性以尽可能排除脆性破坏;高的抗疲劳强度;在材料的工作表面上形成能防止咬粘的二次结构层的能力;相当高的导热性和最佳的热胀系数;
Requirements for Friction Parts Materials The development of modern machine building and transport industries is linked to the increased operating speed and load capacity of the frictional components. The requirements for anti-friction materials are determined by their working conditions and vary widely. However, there is a range of requirements that all anti-friction materials must have in common. These common requirements are: the lowest possible coefficient of friction and high wear resistance; the optimized overall and surface strength, which allows the surface The high strength of the layer in combination with its ability to effectively deform; high enough toughness to eliminate brittle failure as much as possible; high fatigue strength; the ability to form secondary structural layers that prevent biting on the material’s working surface; Thermal conductivity and the best thermal expansion coefficient;
