在决定金属材料的机械性质时,硬度试验是很重要的,一般工件在测定了硬度以后,就可以知道它的耐磨性与切削性,更可以由此而换算出材料的强度极限。试验硬度的方法很多,其中以布氏硬度应用得最广,其他还有洛氏硬度及萧氏硬度等。测量硬度的仪器由于价格较高,携带也不方便,通常主要是在工厂的实验室或 In determining the mechanical properties of metal materials, the hardness test is very important, the general hardness of the workpiece in the measurement, you can know its wear resistance and machinability, but also can be converted from the material strength limit. There are many ways to test hardness, of which Brinell hardness is the most widely used, others include Rockwell hardness and Shore hardness. Instruments to measure hardness due to higher prices, carrying inconvenient, usually mainly in the factory’s laboratory or
