[Test Case] Strength Evaluation of Steel Surface Treatment in the Depth Direction

We will introduce a case that visualizes how the hardness distribution varies significantly with each nitriding treatment.

We will introduce a case study that tested three types of nitriding treatments on the same material. As a result, it was found that there are weak areas on the surface, and that strength and thickness vary significantly depending on the treatment. 【Case Overview】 ■Objective - To identify the strength (hardness) distribution in the depth direction from the surface of shallow surface-treated materials. ■Evaluation - Gas nitriding achieved the minimum erosion rate (maximum hardness) at a depth of 8µm, remained constant up to 12µm, and then gradually increased the erosion rate (hardness decreased) until reaching 20µm, where it stabilized. *For more details, please refer to the PDF document or feel free to contact us.
