FRICTION SURFACING OF STAINLESS STEEL ON LOW CARBON STEEL FOR CORROSION RESISTANCE APPLICATION-AN EXPERIMENTAL APPROACH

摘要

The friction surfacing is one of the friction welding processes, used for deposition of desired material on substrate. These deposits being of solid phase bonding, no external heat source is required and it is very much suitable for critical applications such as wear resistance, corrosion resistance and challenging joining applications. In the present work, the parameters for the optimal performance of the machining operation for acquiring a sound deposit were calculated for Stainless Steel mechtrode and Low Carbon Steel substrate combination. Friction surfacing was carried out on a friction surfacing/stir welding machine. The deposits acquired were tested for the shear strength of the bond, tensile strength of the bond, by preparing the samples from the acquired product. Width of the deposit, height of the deposit, and surface roughness of the deposit were measured by using the respective instruments. The observed values gathered after the testing were verified with the regression equations and the results were analyzed, for the optimal process parameters for acquiring a sound bonding, between the parent materials of Stainless Steel mechtrode and Low Carbon Steel substrate. Based on the analysis of the characteristics of the bond (width, height, surface roughness, shear strength, and tensile strength), by varying the process parameters (frictional pressure, speed and transverse speed) the deposits are found to be fruitfully sound and the aim of the work is fulfilled.
