The quenching hardening layer depth measuring instrument, as a core tool for heat treatment quality control, accurately evaluates the performance of the surface hardening layer of materials through non-destructive testing technology, and is widely used in the fields of bearings, gears, automotive components, and aerospace. Its performance advantages are mainly reflected in four dimensions: measurement accuracy, operational convenience, environmental adaptability, and data management efficiency, providing key support for manufacturing process optimization and quality control.

1、 High precision measurement: error control and detail capture

The depth measuring instrument for quenching and hardening layer adopts the principle of ultrasonic or eddy current detection, and achieves depth positioning by capturing material microstructure differences (such as grain changes between martensite and ferrite). Ultrasonic technology utilizes the difference in scattering characteristics of sound waves between the hardened layer and the base material, combined with12bitADHigh speed sampling and120dBGain adjustment can clearly identify the position of waveform jumps and accurately locate the layered interface. The eddy current law induces the surface eddy current attenuation speed of materials through high-frequency alternating magnetic fields, combined with intelligent algorithms to analyze changes in conductivity and generate depth-Hardness curve, both techniques control errors within a very small range, meeting the stringent requirements of high-end manufacturing for process consistency.
