Reduction in welding and chipping at the tip! A case where production has become possible up to 12,000 shots.
We would like to introduce a case where "Kanack OX treatment" was applied to a pin. Due to the pin's withdrawal angle of 0.05 degrees, galling occurred at the aluminum weld at a distance of 150mm from the pin tip, leading to a low lifespan. As a result, we decided to test Kanack OX treatment, conventional nitriding treatment, CVD (three-layer), and PVD (CrN) surface treatments. As a result, production became possible up to 12,000 shots, and the welding and galling at the tip were reduced, leading to improved productivity. [Case Overview] ■ Conventional Issues - Aluminum welding - Occurrence of galling ■ Treatment Effects (due to improved surface hardness) - Suppression of welding - Suppression of galling *For more details, please refer to the PDF document or feel free to contact us.

Company information
Kanak processing is a gas nitriding treatment using a unique method. The material is held in a heating atmosphere of around 500°C for several hours, allowing nitrogen to diffuse and permeate from the steel surface, reacting with metal elements to form a hardened layer. Unlike conventional nitriding treatments, there are very few brittle iron nitride compounds near the surface, and the high compressive residual stress and smooth hardness distribution are characteristics of Kanak processing.
