Abstract
In this work, the wear test of uncoated and titanium nitride coated AISI D2 cold work tool steel against silicon nitride ball was realized at 0.3 m/s sliding speed and under the loads of 2.5N, 5N and 10N. Steel samples were nitrided at 575°C for 8 h in the first step of the coating process, and then titanium nitride coating was performed by pack diffusion coating in a powder mixture consisting of ferro-titanium, ammonium chloride and alumina at 1000°C for 2h. Nitro-titanized samples were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), micro-hardness and ball on disk wear tests. X-ray studies showed that the phases formed on the coated steel surfaces are TiN and Ti0.5Cr0.5N. The average hardness of the layer is 1450±30 HV0.005. The friction coefficient value of TiN layer is ranging between 0.136–0.203. The specific wear rate of coated steel is 0.982×10^-5 mm3/Nm.
