Nitriding Method "S.P.N. Method"

It can be safely applied to mirror-finished products and textured surfaces with minimal skin irritation from processing.

The "S.P.N. method" is a nitriding process for steel that utilizes plasma energy, differing from the conventional ion nitriding method that uses traditional plasma power. It causes less roughness on the surface of the treated material and can suppress the formation of compound layers, which are considered a drawback in the case of alloy steel. Therefore, it features reduced "dimensional changes" and "brittleness" compared to conventional methods. [Features] ■ Nitriding is possible for almost all types of steel, including stainless steel. ■ Stable glow can be maintained even for slit processed products, resulting in less variation. ■ Welding corrections can be performed directly after treatment. ■ By applying it to cutting tools and dies, and using it as a pretreatment for hard coatings such as PVD and DLC, greater effects can be achieved. *For more details, please download the PDF or contact us.
