Abstract:A new surface modification technique, called "iron-powder pack (IPP) treatment", has been proposed. During IPP treatment, carbon and nitrogen diffuse into a metal substrate by treating it with a mixture of iron and carbon powders at high temperature in a nitrogen flow. This paper describes the effects of adding alumina to the mixture of iron and graphite powders on the microstructures and hardness of SUS430 ferritic stainless steel after IPP treatment. The alumina powder was added to prevent powder mixtures fr… Show more

“…When alumina powder is added as a reliable anti-sintering agent to a mixture of iron and graphite powders, both carbon and nitrogen diffuse into the steel. 13) We have named such a surface modification technique "iron-powder pack (IPP) treatment". It has been confirmed that the iron powder acts as an important agent for enhancing the diffusion of carbon from the powder mixture to the specimen.…”
