background

Surface quenching and hardening can improve the wear resistance and fatigue strength of dynamically stressed components. Common application areas include:

Surface hardening optimization

Improving fatigue resistance and roller strength by compressing residual stress

█ Friction performance optimization

█ Improve wear and corrosion resistance performance

For high-quality surface hardened products, the depth of surface hardening layer (SHD) is a crucial quality indicator. If there is no non-destructive testing method, the only way to ensure the quality of heat treatment is through destructive measurement of random samples, which not only damages components, is expensive, but also wastes time and has extremely low productivity.

resolvent:

As an alternative to destructive testing techniques such as optical analysis or hardening depth analysis, the Fraunhofer Institute for Non Destructive Testing Technology IZFP in Germany uses a rapid non-destructive ultrasonic method to measure the depth of the surface hardening layer (SHD). This non-destructive measurement technique uses the backscattered signal generated in the transition zone between the hardened layer and the matrix structure to measure the corresponding depth of the hardened layer. By utilizing the mechanical and structural differences in the microstructure of the matrix material of the surface hardening layer, and optimizing the ultrasonic frequency combination of backscattered echoes, reliable and reproducible SHD measurement results have been achieved for users.

The P3123 SHD quenching hardening layer non-destructive measurement system is based on this effect and measures the thickness of the surface hardening layer by evaluating the ultrasonic flight time between the surface echo signal and the backscattered echo signal from the transition zone. Due to the clear ultrasonic velocity of the material, the depth of the surface hardening layer can be directly calculated.

The excellent non-destructive measurement method for surface hardening layer depth, P3123 SHD, has high demand in the energy industry, large-scale rolling bearing production, as well as truck and automotive crankshaft manufacturing. Our innovative technology has also entered other industries, providing users with a variety of customizable solutions.

The P3123 SHD non-destructive measurement system can fully optimize manufacturing parameters, reduce testing workload, and lower costs. By adjusting production processes in a timely manner, it can achieve rapid manufacturing control functions and good quality management, ensuring that products always have high quality.
