超声硬度试验法,是利用超声原理来测定硬度的方法。这种方法国外是近年来才建立和发展起来的,并制成不同类型的超声硬度计,使它得到了广泛的应用。遵照毛主席“洋为中用”的伟大教导,我厂广大革命职工,“破除迷信,解放思想”在各兄弟单位的大力协助下,批判地引进了国外技术,经过一年多的反复实践,对仪器的电气部分和机械结构进行了不断的改进,试制成功了 HC-1型超声硬度计。一、超声硬度试验法的作用原理超声硬度试验法,是利用超声传感器杆的谐振频率随试件硬度而改变的特性,所建立起来的一种新的硬度测量方法。超声硬度计探头中的传感器杆,一端和一个大质量刚体固定在一起,另一端镶有136°金刚石角锥压头。
Ultrasonic hardness test method is the use of ultrasound to determine the hardness of the method. This method is only in recent years abroad to establish and develop, and made of different types of ultrasonic hardness, it has been widely used. Following the great teachings of Chairman Mao’s “foreign work is for the middle”, the revolutionary workers and workers of our factory extensively criticized the introduction of foreign technology with the vigorous assistance and assistance of various fraternal units. After over a year of repeated practice, The electrical part of the instrument and the mechanical structure has been continuously improved, trial-produced HC-1-type ultrasonic hardness tester. First, the principle of ultrasonic hardness test Ultrasonic hardness test method is the use of ultrasonic sensor rod with the resonant frequency of the specimen changes the hardness of the characteristics of the established a new hardness measurement method. Ultrasonic hardness sensor probe in the probe, one end and a large mass rigid body together, the other end is set with a 136 ° diamond pyramid head.
