Extension of fatigue life and improvement of product destruction strength! Measures against pitching in carburized gears!
"WPC processing" is a surface treatment heat treatment method for metal products, in which shots with a hardness equal to or greater than the product hardness, ranging from 40 to 200μm, are injected at a speed of 100m/sec or more, raising the temperature near the surface above the A3 transformation point. It can significantly reduce the surface abnormal layer of gas carburized products. Additionally, the micro-dimple effect greatly reduces sliding resistance and prevents pitching. 【Features】 ■ Extension of fatigue life ■ Improvement in wear resistance and pitching resistance ■ Prevention of stress corrosion and intergranular corrosion in stainless steel and Inconel ■ Reduction of sliding resistance and fluid resistance, decrease in heat generation, and reduction in wear ■ Improvement in the breaking strength of products *For more details, please refer to the PDF document or feel free to contact us.

Company information
Since our founding in 1909, we at TONEZ have been pursuing technology and quality in heat treatment. Utilizing the technical skills we have honed over many years, we are now highly regarded in a wide range of fields, including automotive parts, large materials and components, and heat treatment for aerospace equipment parts that require high reliability. We can accommodate various treatments, from material heat treatment (quenching and tempering, annealing, etc.) including round bars, to surface heat treatment of finished products (carburizing, gas nitriding, gas soft nitriding). We can handle everything from single products to mass production. In terms of quality, we have obtained "ISO 9001" and "JIS Q 9100" certifications, establishing a world-standard quality management system.
