The surface properties of hot work steel modificated with pulse plasma treatment
Abstract
In this study, the surface properties of a W360 ISOBLOC as hot work steel was investigated in respect to mechanical and microstructural aspects. Three were three different sample-plasma gun nozzle distances (30, 40 and 50 mm) and three different pulse number (5,10 and 15) were chosen for the surface modification at a constant battery capacity of 800 mf. After pulse plasma surface treatment, the modified surface layers were examined using an optical microscope. The SEM and EDS analyses were applied to surface on samples. It was observed that surface treatment affects the formation of a new structure. XRD analyses was done. The new phases were formed such as FeN, Fe2N, g- Fe, W3O which is located in the modification layer. The samples were also subjected to micro-hardness measurements. It was found that the hardness values of modified surfaces are 4-6 times higher than that of the untreated samples.
