EVALUATION OF BOND QUALITY AND CORROSION RESISTANCE OF STAINLESS STEEL-LOW CARBON STEEL FRICTION SURFACED DEPOSIT

Friction surfacing is an advance surface modification process and it is solid phase welding technique by means of which similar and dissimilar metals easily be deposited one over the other effectively. This process preferable to get some special properties for the surfaced deposits of mechanical properties such as, shear strength or tensile strength, chemical resistance, wear resistance, corrosion resistance and electrical properties. In this study, details of the variants of friction surfacing techniques, the weldability of the stainless steel with the low carbon steel, selection of process parameters to get the desired properties, a deposit of corrosion resistance, mechanical testing of deposits and industrial applications are discussed in detail. By designing 23 experiments, the optimum parameters required for obtaining the desired responses of properties of bond strength, such as tensile strength and shear strength, surface roughness, width and height were determined. Also discussed are the effects of the parameters on the properties. The results of the corrosion test are discussed with applications like chemical pumps, pressure vessels and joining of dissimilar metals. Friction welding process has been commercialized in view of its importance and applications in defense, aerospace, electrical, automobile and many other industrial sectors
