Solid particle erosion (SPE) behaviour of different hardfacing electrodes deposited on gray cast iron (ASTM 2500) was studied using quartz sand and iron ore as erodent particles. Erosion test was carried out as per ASTM G76 test method. Considerable differences in erosion rates were found among different hardfacing electrodes at normal impact. Both volume fraction of carbides and type of carbides...
The abrasive wear behaviour of different hardfacing electrodes deposited on grey cast iron used for the top bearing plate of a coal crushing unit was studied using the dry sand rubber wheel abrasion test. The results show that different hardfacing electrodes as well as the weld procedure variation using similar electrodes have large effects on low stress abrasion resistance of the deposit. Such effects...
