国产布氏硬度计及布洛维三用硬度计配用测量压痕的读数显微镜,在热处理现场生产中,对于检验硬度和渗碳(包括碳氮共渗)渗层深度,是必用的测试仪器。但在生产中遇到不少的问题,例如:许多试片都小于读数显微镜底座的孔径,测量不方便。若另外作夹具,十分繁琐,效率低,不方便。又如在车间生产中、光线一般都不太好。热处理调质零件的表面光洁度也不好,另有一
Domestic Brinell hardness and Brody three hardness tester equipped with a measurement of indentation reading microscope in the heat treatment on-site production, for testing hardness and carburizing (including carbonitriding) infiltration layer depth, it is necessary test equipment . However, in the production of many problems encountered, for example: many specimens are less than the reading aperture of the microscope base, the measurement is not convenient. If the other for the fixture, very cumbersome, inefficient, inconvenient. Another example in the workshop production, the light is generally not very good. Heat treatment of the surface finish of quenched parts is not good, another one
