Abstract: Abrasive wear is the most important influencing factor to be considered to determine life span of soil-engaging tools, especially in the case of agricultural tillage tools. A comparative study has been reported on three-body abrasive wear of normal plough tool and hardfaced plough tool materials as per ASTM G 65 standard. Hardfacing is done by manual arc welding using ZEDALLOY VB hardfacing electrode. An orthogonal array and analysis of variance are employed to investigate the optimal testing parameters. The experimental results demonstrated that the major parameter found is applied load among the other controlling factors on abrasive wear. The hardfaced plough tool material shown marked wear resistance compared to normal plough tool material.
