Abstract: The influences of hardfacing deposit and deep cryogenic treatment on three-body abrasive wear behaviour of AISI 1013 steel were studied. The three-body abrasive wear tests were carried out using the dry sand/rubber wheel test rig as per ASTM G65 standard. Hardfacing was done by manual arc welding using ZEDALLOY VB hardfacing electrode. The deep cryogenic treatment was carried by using liquid nitrogen temperature at −196°C. The applied load, sliding velocity and sliding distance were considered as process parameters. Experimental results reveal that the hardfacing deposit showed the highest abrasive wear resistance as compared to deep cryotreated material. Worn-out surface observation by SEM witnessed same behaviour. The nature of material removal was microploughing or microcutting depending on the attack angle, due to cracks formed on the surface of material.
