Surface burn during grinding processes is a thermally induced damage creating unwanted
changes and must be avoided. Previous studies correlated surface burn with a critical
temperature as its threshold. In this study, metal oxidation at high temperatures is proposed
as the mechanism responsible for burn, and a model is developed considering both
temperature and exposure time to predict the occurrence of burn and its thickness. Grinding
tests were carried out and the cross-sections of the samples were analyzed to validate the …
