Wear takes predominant role in reducing the life time of moving parts in machines having rotating and sliding motion and also the cutting life time of tool materials. Hard wear resistant coatings have been used to increase the wear resistance of these parts. This investigation focuses on the influence of FUTURA NANO(TiAlN) and ALCRONA PRO(AlCrN) coatings on mild steel (ms) material. TiAlN and AlCrN were coated on two different mild steel discs by using physical vapour deposition (PVD) technique. The stainless steel pins are selected as a work piece material. Methods for determining the wear on surfaces can be categorized according to the type of relative movement of the tested material and the applied bodies and the method of contact and its geometry. One of the method is more frequently used for wear on surfaces is the pin on disc method. The wear characteristics were analysed and compared between two different coatings(TiAlN and AlCrN) upon machining the stainless steel pins. The performance parameters were calculated by using coefficient of friction values which were obtained from the pin on disc test. Substantial resistance to wear has been achieved by the coatings.
