Impact wear of mild steel has been studied in light of impact angle reversal. An in-house built, specially designed test rig has been used to facilitate test conditions, including impact angle reversal. Metallographic examination and scanning electron microscopy were used to analyze the morphology of impact surfaces. Results showed lower impact wear under condition involving impact angle reversal for the whole range of impact angles. Furthermore, multiple impact direction reversal showed significant impact wear reduction. Behavior has been explained in terms of failure due to plastic deformation accumulation.
