摘要

Friction surfacing is a novel solid state surface coating process with several advantages over conventional fusion welding based surfacing processes. In the present work, austenitic stainless steel (AISI304) was friction surfaced on low alloy steel substrate using specially designed and developed machine by DMRL. Experimental results showed that stainless steel bonds well with low alloy steel with adequate bond strength and it depends on selection of optimum process parameters. The response surface methodology is employed in the experimental investigation of the effect of operating parameters named rotational speed, traverse rate of substrate and feed rate of mechtrode on the process response of bond strength, coating thickness, coating width, coating regularity and pitting corrosion resistance. The experimental data was obtained against a full factorial design at three levels, that allowed main and interaction effects on the process response. The observed properties were correlated with microstructure, XRD and diffusion of elements across interface. The statistical analysis indicated that axial force on mechtrode and traverse rate of substrate rate are the most significant factors for the optimization of coating parameters.
