The wear failure is widely found in steel bars used for coal screener machines in the mining industries. The failed parts of such components require immediate replacement to lengthen the machine's service life. This work aimed to investigate the structure and properties of the worn bar of a screener machine after experiencing wear failure and analyze the wear mechanism. The work started by machining the sample from the original bar, then grinding and polishing. The microstructure of the worn samples was observed using SEM and XRD. The hardness distribution of the bar was measured from the periphery to the core. The results of this work would provide evidence of wear sources responsible for the wear failure. |
