Investigation on microstructural and mechanical properties of HVOF sprayed Inconel-718 coatings on grey cast iron

Authors(4) :-Hitesh Vasudev, Harmeet Singh, Lalit Thakur, Jasmaninder Singh Grewal

In the present work Inconel-718 powder was deposited on grey cast with High velocity oxy-fuel (HVOF) thermal spray coating technique. The thickness of coating was kept 220µm with powder having average particle size of 45µm. The deposited coating was characterized with Scanning Electron Microscope (SEM) equipped with Energy Dispersive Spectroscopy (EDS) and Optical Microscope (OM). Microstructure analysis reveals the splat by splat formation of coating with good mechanical keying to the substrate. Further the microhardness was investigated and it was found that the microhardness of Inconel-718 coatings is (567Hv) significantly 2.5 times higher than base material microhardness (229Hv).
