In Figure 2, cratering at the chamfered edge of CC650 was noted, which was not present in CC620.This indicates a higher chemical stability of CC620 compared to CC650 containing 30% of TiC withhigher solubility in iron [35]. The abrasive wear mechanism could be deduced from the abrasive markson the tools flank of each tool.J. Manuf. Mater. Process. 2018, 2, x FOR PEER REVIEW 5 of 14
