Abstract
In the present work, similar joint of AISI 304 austenitic stainless steel with a designed joint interface by 6 mm diameter and 6 mm depth, were processed by rotary friction welding route. Different parameters including forging pressure (192.4, 240.5, 288.6 and 384.8 MPa), friction pressure (192.4 MPa), frictional speed (560 RPM) and frictional time (1min) are examined. Pin on disc wear tester was used for wear test with counter disc SAF 2205 duplex stainless steel and cylindrical AISI 304 pin specimens. The surface roughness of duplex stainless-steel disc was measured. The wear rate in terms of weight loss were obtained for the pin specimens. The results of designed joint interface specimens showed better wear resistance than as-received. The variation of increasing wear loss with sliding distance has been found to be uniform for all the specimens. Further, it was noted from the experiments that the wear rate increased with increasing forging pressure.
