This paper, the friction and wear behaviours of High Velocity Oxy – Fuel sprayed iron based amorphous metallic coatings and AISI 316 stainless steel sliding against a sintered tungsten carbide disc were studied in terms of mass loss and coefficient of friction under various operating conditions such as applied load, sliding velocity and distance by Pin on Disc tribometer. The surface morphology of the coated and uncoated materials was characterized by optical microscopy images. From these images, wear mechanisms of the worn surfaces of the test specimens were discussed adequately and it was found that the dry sliding wear behaviour of the HVOF sprayed iron based amorphous coated specimens exhibited superior wear resistance than the uncoated stainless steel specimens.
