里氏硬度测试法是由美国Dr.Leeb于1978年首先提出的一种动载式金属硬度测试法。工作原理是:一个端部为WC球的冲击体在弹簧的推动下,通过一个线圈垂直地冲向试件表面并回弹。其冲击与回跳速度在线圈中会感应出与其成正比的电压值。两个电压的比值可以精确地反映出试件的硬度。里氏硬度仪主要由“冲击装置”(速度传感器)和数据处理器两部分组成。由中国机械工程学会工业技术咨询服务公司(北京海淀彩和坊19号)引进国外的硬件结合自己的软件技术开
Leeb hardness test by the United States Dr.Leeb first proposed in 1978, a dynamic load metal hardness test. The working principle is: one end of the WC ball impact body in the spring-driven, through a coil perpendicular to the test piece surface and rebound. The impact and rebound speed in the coil will be induced in a proportional voltage value. The ratio of the two voltages can accurately reflect the hardness of the test piece. Leeb hardness tester mainly by “impact device ” (speed sensor) and data processor in two parts.
