Effect of Active Screen Plasma Nitriding on Mechanical Properties of Spheroidal Graphite Cast Iron

Spheroidal graphite cast iron is a material with wide range of uses such as in automobile parts. By applying active screen plasma nitriding (ASPN) treatment, the use spheroidal expanded, and it can be expected to used under special load conditions. In this study, we evaluated effect ASPN treatment on mechanical properties iron. With nitride layer was formed sample surface diffusion further inside layer. The thickness increased temperature increased. hardness improved by treatment. abrasion resistance longer time resulted higher resistance. fatigue strength strength. also corrosion
