Depth Measurement Of Carburizing/Nitriding/Hardening Layer

Accurately evaluate the surface treatment effect of components by measuring the depth of carburizing/nitriding/hardening layers. By detecting the penetration depth and microstructure changes after carburizing, nitriding, or hardening treatment, it is possible to determine whether the process meets the standards and ensure that the component has the expected wear resistance, fatigue resistance, and other properties.

Depth Measurement Of Carburizing/Nitriding/Hardening Layer

This is crucial for ensuring the quality of mechanical parts and extending their service life. At the same time, it helps enterprises optimize process parameters, control production costs, and provide key data support for failure analysis, which is the core link to enhance product competitiveness.

| Test Objective

Check the penetration depth and microstructure changes of components after surface carburizing, nitriding or hardening treatment.

| Service Products / Fields

Steel parts subjected to surface treatments such as carburizing, nitriding, decarburizing, and carbonitriding, as well as steel parts after induction hardening.
