“…Alexandru Paraschiv et.al: [9] The author as investigated the thermal coated steel substrate using electric arc, atmospheric plasma spray and high velocity oxy-fuel spray. Mo coatings deposited by three thermal spray techniques such SEA, APS and HVOF methods are investigated by tensile bond strength and Vickers indentation tests in order to evaluate and correlate the two of most important mechanical properties of the thermal sprayed coatings such as, cohesion strength and fracture toughness.…”

Steel rollers are most commonly used in conveyor system across different industries like mining and construction. In the conveyor rollers used in mining industry, the steel specimen of the roller is in continuous contact with another metal of the same or different material rolling and sliding on that surface. In this motion of the roller, the third body i.e., the sand, grits and dust of various sizes may be entrapped in the interface of the roller material. The third body induced causes the wear due to its abrading action. To reduce this abrading action, a layer of molybdenum coating is developed on the steel substrate to improve its wear resistance by using the plasma spray technique, a thermal spray method. The experimental procedures were performed according to standard ASTM G65 method. The results were compared and tabulated in full factorial method. The SEM and EDAX results were obtained. The average specific wear rate [Ks] of the coated specimen is reduced by 30% when compared with the uncoated specimen.
