Induction hardening is a mature technology that can improve the load resistance of components such as bearings, gears, and rollers, and protect surfaces from wear. The hardening process is carried out by induction heating the near surface area above the austenitization temperature and subsequent water cooling. This usually produces a martensitic microstructure with appropriate hardness and strength near the surface, which is separated from the lower hardness but tough substrate by a transition zone. The hardening depth is defined as the distance from the surface when the hardness is lower than the given level defined by the relevant application standards.

P3123On the surface of shafts, bearings, gears, and other machine parts, especially large rotating bearings in open-pit mining equipment and wind power plants, high stresses are generated at the mechanical contact points and in the volume area below, which can absorb the Hertz pressure of the material, which is higher than the stress that occurs. This high-strength layer is generated through surface hardening, which produces a martensitic surface layer that decreases to the hardness of the uncured core in a relatively narrow area

An innovative technology for measuring induction hardening depth using ultrasonic methods can significantly reduce testing time and cost, provide real-time results, and eliminate the need to cut or damage samples of any size. This instrument is produced by Q NET Engineering GmbH, which specializes in non-destructive testing of materials (NDT).

The device consists of an industrial laptop with 4 inputs, which can connect different sensors (in parallel) to these inputs so that there is no need to replace probes when planning to perform analysis of different geometric shapes. The computer has a software for processing ultrasonic signals, SHD Studio (abbreviation SHD stands for surface hardness depth, or "surface hardening depth").
