材料抵抗其他物质刻划或压入的能力称为硬度。测定硬度的方法有划痕法、压入法、弹性回跳法、抗磨耗法等。根据测定的方法不同,可用不同的量值来表示硬度。这些不同的量值之间没有一定的换算关系。也就是说,只有用同样的方法、在同样的条件下,在相同的硬度计上所测得的量值才有可比性。表示硬度的各种方法有:巴氏硬度(Ba-rcol hardness)、布氏硬度(Brinell hardn-ess)<亦称白氏硬度>、洛氏硬度。(Rockwell
The ability of a material to resist marking or pressing against other materials is called hardness. Determination of the hardness of the scratch method, pressing method, elastic rebound method, anti-wear method. According to the determination of different methods, different values can be used to represent the hardness. There is no certain conversion between these different magnitudes. In other words, only in the same way, under the same conditions, the measured value on the same durometer comparable. Various methods of indicating hardness include: Ba-rcol hardness, Brinell hardness, Rockwell hardness. (Rockwell
