Abstract
The present research work examines the impact of temperature on the dry sliding wear behaviour of AA7075 aluminium strengthened zirconium diboride (ZrB2) particulate composite (0, 3, 6, 9 and 12 wt.%). AA7075/ZrB2 aluminium matrix composites (AMCs) were prepared by the in-situ reaction of K2ZrF6 and KBF4 to liquid aluminium. The in-situ handled AMCs were described utilizing FESEM, XRD and EBSD. The XRD pattern of the AMCs uncovered the presence of ZrB2 particulates in the matrix. The dry sliding wear behaviour of the AMCs was inspected utilizing a pin on disc machine at differing temperatures (40, 60, 120, 180 and 240OC). The wear resistance of AMCs expanded with the expanded substance of ZrB2 particulates at all test temperatures. The worn surface of the AMC pins was described utilizing FESEM.
