Material loss due to slurry erosion is a serious problem in many industrial applications like hydraulic turbines, slurry pumps, pipe lines, etc. where the ideal choice of engineering materials is a real challenge. Lightweight aluminum alloys are finding wide applications in the field of aerospace automobile, defence, etc. due to improved physical, mechanical and tribology properties. HVOF (High velocity oxy fuel) Sprayed coatings provide protection against corrosion, erosion and wear. Inconel - 718 is a metallic coating which has good wear and erosion resistance. This was sprayed on to mild steel substrate and then subjected to slurry erosive wear tests. It is observed that the slurry wear rates of mild steel decreased on coating the substrate material with Inconel - 718. The tests were conducted in a slurry erosive wear tester at varying spindle speeds (500 -1500rpm) at different intervals of time .The wear loss was recorded experimentally compared with theoretical values and graphs are plotted to check accuracy. For this comparison, various parameters such as impinging particle size, velocity of solid particles, concentration of slurry bath, hardness of mild steel, time are correlated to obtain a theoretical formulation. A non-dimensional analysis is also done to reduce the number of parameters influencing the wear rate.
