INVESTIGATION OF WEAR BEHAVIOUR OF PLASMA NITRIDED X40CrMoV5-1 HIGH ALLOY STEEL
Abstract :
X40CrMoV5-1 high-alloyed steel was plasma nitrided for different treatment times (3h, 5h and 7h) and temperatures (450, 500 and 550 °C) under at a constant gas mixture (75% H2+25% N2). The plasma nitriding properties of X40CrMoV5-1 high-alloyed steel have been examined by evaluating phase composition, hardness profile, compound layer thickness, case depth and wear strength. It was found that double layers (compound and diffusion) formed on the surface of the samples and increasing of treatment time and temperature has increased the layers thicknesses. It was found that plasma nitriding improves the wear strength, which depends on thicknesses and hardness of the diffusion layer, but the compound layer reduces the wear resistance by breaking off and forming abrasive particles because of the high hardness.
