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 http://localhost:8080/xmlui/handle/123456789/811 Title: Tostudy the corrosion behavior of friction stir processed magnesiumalloy AZ91.Materials Today: Proceedings, Authors: Sidhu, H Singh; Kumar, P; Singh, B et al. Abstract: The main aim of the study is to investigate the effect of the corrosion behaviour of Friction Stir Processed (FSPed) AZ91 magnesium alloy. The corrosion testing was performed by immersing the FSPed samples in 3.5 % (by weight) sodium chloride (NaCl) solution. It is originally proved that the corrosion rate of AZ91 FSPed samples decreased significantly with a square pin profile as compared to the round pin profile. It is attributed that the pulsation effect of the flat-faced tool helped to improve the flow of material. Also, Friction Stir Processing (FSP) modified the surface morphology and uniformly distributed the β-Mg17Al12 phase particles that helped in improving the corrosion rate of AZ91 alloy. 2020-01-01T00:00:00Z
