摘要： A process for duplex heat treatment of combined nitriding treatment and induction quenching treatment on an iron and steel material includes a chemical conversion treatment step for forming a chemical conversion film on a nitrogen compound layer formed on the iron and steel material by the nitriding treatment, after the nitriding treatment and before the induction quenching treatment. A compound layer formed on a surface of an iron and steel material by nitriding treatment is prevented from being oxidized by induction quenching, so that unevenness in film thickness between different portions of an oxidization-inhibiting film does not easily occur, with the result that a nitrogen-containing compound layer obtained after high-frequency heating remain uniformly.
