“…The effect of the time and the temperature of plasma nitriding on structural properties of AISI 4340 steel was investigated [3]. The nitriding treatment in a salt bath at 580°C is an effective method for improvement of the corrosion behavior and surface properties of the low alloy steel C15 [4]. The microstructure and hardness of nitride steel were studied after applying a laser re-melting which caused the decomposition of compound zone at the surface and an increase in hardness corresponding to the martensite in re-melted and heat effected zone [5].…”

The present study has been conducted in order to obtain iron nitrides layer on AISI4140 steel by using plasma nitriding treatment. As one of several parameters of this process, the nitrogen rate ranging from 10 to 70% with a step of 20% was chosen. The structure, the morphology, the thickness and the hardness of iron nitrides layer were investigated. As a result, the improvement of surface hardness of nitrided steel was identified related with the increase of compound layer thickness due to the increase of activation rate. The steel substrate treated at high activation rate presents hardness 3 times higher than that of untreated steel.
