SLIDING WEAR BEHAVIOUR OF AISI 304 AUSTENITIC STAINLESS STEEL AT ELEVATED TEMPERATURE
Keywords:
AISI 304, Sliding Wear, Load, High Temperature, SEMAbstract
The study analyses the tribological properties of commercially available 304 Austenitic stainless steel (SS) under dry condition. Pin on disc wear test enabled to study the wear resistance and coefficient of friction on the basis of friction force obtained in the course of continuous measurement under different load (30N and 50N) and temperature (30 ºC and 100ºC). To study the mass loss, the weight of the disc and the pin were measured using an electronic analytical balance. Scanning electron microscope pictures of the worn surfaces were analyzed to identify the wear mechanism. The rate of wear at 100°C was higher than 30°C. As time advances, the variation of wear was progressively increased. The worn surface at 100°C shows the delaminated multiple layer with flakes, indicating the layer by layer removal of the disc. The coefficient of friction in 100°C was marginally higher due to the sliding wear at higher temperature
