制动摩擦片的高氏硬度

[中文适用范围]： 硬度测量用于对制动衬片的配方和加工的一致性进行质量控制检查。戈根硬度是非破坏性的（穿透器会导致浅表面变形。）。戈根硬度法本身并不能显示衬片用作制动器摩擦元件时产生摩擦或抵抗褪色的能力。硬度和硬度范围因每种配方、厚度和轮廓而异；因此，制造商必须为每种配方和零件配置建立可接受的值和范围。烧结粉末金属衬里的硬度通常用洛氏表面硬度设备测定。参见 ASTM B 347。 [外文原描述]： Hardness measurements are used as a quality control check of the consistency of formulation and processing of brake linings. Gogan hardness is nondestructive (the penetrator causes shallow surface deformation.). Gogan hardness method alone does not show anything about a lining’s ability to develop friction or to resist fade when used as a friction element in brakes.The hardness and the range of hardness are peculiar to each formulation, thickness, and contour; therefore, the acceptable values and ranges must be established for each formulation and part configuration by the manufacturer.Cross Reference: ASTMB347,J2654_201508
