Abstract
The research paper focuses on evaluating the dry sliding wear behaviour of plasma sprayed coatings like red mud (RM), RM + 5% Fly Ash (FA) and RM + 5% FA + 5% Al on mild steel cylindrical shape substrate. Spraying was done at 10 kW operating power level. A conventional pin on disc wear tester is adopted for wear analysis. The wear test was performed at track diameter of 50 mm and sliding speed of 60 rpm (0.157 m/s) with normal load of 10 N. The duration of sliding varies from 54 minutes for pure red mud coating to a maximum value of 102 minutes for RM + 5% FA + 5% Al composite coating. A significant decrease in wear rate (in terms of mass loss) is observed by reinforcement of fly ash and aluminium to red mud, which might be due to improved interfacial properties.
Highlights
Coating technology is an emerging research in engineering application
Wear behaviours of plasma sprayed red mud coatings made at 9 kW operating power level, reinforced with varying weight % of fly ash, aluminium, carbon have been analysed at different operating conditions [16]
The objective of this research work is to study the mechanical and dry sliding wear behaviour of red mud coatings reinforced with additives like fly ash and fly ash + aluminium separately and comparing the results, inciting red mud as suitable coating material may be implemented for replacing the conventional coatings
Summary
Coating technology is an emerging research in engineering application. Wear resistive materials are fabricated by means of coating for wide tribological applications. The importance of mechanical and tribological properties has convinced many researchers to study the friction and wear behaviour and to improve the wear resistance of composite coatings [7]. Wear behaviours of plasma sprayed red mud coatings made at 9 kW operating power level, reinforced with varying weight % of fly ash, aluminium, carbon have been analysed at different operating conditions [16]. The objective of this research work is to study the mechanical and dry sliding wear behaviour of red mud coatings reinforced with additives like fly ash and fly ash + aluminium separately and comparing the results, inciting red mud (with additives like fly ash and aluminium) as suitable coating material may be implemented for replacing the conventional coatings
