Hardfacing plays a major role in an industry and agriculture in reducing losses due to wear. In the present work three different types of hardfacing electrodes namely H1, H2 and VB were used to enhance the wear resistance of EN-47 steel, used for tillage application in agriculture sector by manual metal arc welding (MMAW) process. The abrasive wear behaviour of bare and hardfaced steel was evaluated by using dry sand rubber wheel tester according to procedure A of ASTM G65 standard. Microstructural characterization and surface analysis of worn out and fresh samples were made by using Optical and scanning electron microscopy. It is found that hardfaced steel (H1, H2 and VB) has significantly shown better wear resistance than bare steel. The wear resistance indices (WRI) of different steel hardfacings i.e. H1, H2 and VB were found to be 1.58, 1.37 and 1.82 respectively. The microstructure of VB hardfaced steel was found laminar dendrites 2020-01-01T00:00:00Z
