Abstract
The present experimental work has attempted to analyze the influence of substrate heating on coating geometry during the deposition of stainless steel over medium carbon steel substrate using friction surfacing process. Inductive heating was applied to the substrate plate using an electric unit with three different temperatures of 200 °C, 400 °C, and 600 °C. Elemental process parameters like axial force, rotational speed and transverse speed with different combinations were considered for conducting experimental work. The material consumption rate (CR) and deposition rate (DR) were extensively studied. The high rate of material consumption and deposition were seen at samples obtained from 600 °C of inductive heating compared to the conventional friction surfacing process. Using the IR thermometer, the interface temperature at both the advancing and the retreating side was recorded which showed a higher temperature was experienced by advancing side than the retreating side. The mechanical strength of the coating was analyzed by micro hardness and bending tests. Interfacial attributes of the coating were analyzed by using FE- SEM images and the elemental composition at the coating interface was studied through the EDAX report.
