This paper describes the friction and wear behaviour of Cr2O3/Ni8.5Cr7Al5Mo2Si2I32FcTiO(2) coatings for bearing materials. These coatings were successfully deposited on low carbon steels using a flame spray technique. The produced samples were characterized by means of an optical microscope and microhardness tester. The microstructural observations showed that the layers contain some inhomogeneities such as porosity, crack-like defects, unmelted particles, oxides and inclusions. The structures with the inhomogeneities strongly influence their wear/friction properties. The friction and wear experiments were performed under dry and acid environments using a pin-on-plate configuration against AISI 303 counter material for different loads. It was found that in acid environment, the amount of wear loss is less than that of in dry condition and applied load level is more effective in dry condition.
