In this research work, low-temperature carburizing of AISI 420 martensitic stainless steel was conducted at 460 °C for different amounts of time using an acetone source. The microstructure and
AISI 420 is a martensitic stainless steel that offers a high hardenability and strength. It also offers an excellent corrosion resistance to acidic and alkaline substances. Alias AISI 420 …
The wear resistance of AISI 420 stainless steel was also improved evidently by plasma nitriding. These results showed that plasma nitriding AISI 420 stainless steel at anodic potential (ground 0 V) provides an alternative process to increase the surface hardness, wear resistance as well as the corrosion properties with no evident edge-effect.
