对于最广泛应用于生产和科学研究的洛氏、布氏、维氏等各种工作用硬度计,其工作原理均是采用一个压头,在一定的载荷作用下压入试件、以压入深度或压痕面积上所承受的载荷来表示硬度值。从这个工作原理可以知道,压头的物理性能和几何精度、测量压痕用的装量的精度及载荷的精度是硬度计示值准确性的三大因素。载荷是硬度计准确性
For the most widely used in production and scientific research Rockwell, Brinell, Vickers, and other work with the hardness tester, the working principle is the use of a pressure head, under the action of a certain load into the specimen to be pressed The depth or indentation area to bear the load to represent the hardness value. It can be seen from this working principle that the physical properties and geometric accuracy of the indenter, the accuracy of the loading quantity for measuring the indentation and the accuracy of the load are the three major factors of the indication accuracy of the durometer. Load is durometer accuracy
