Chipping resistance test
WebJan 1, 2013 · The resistance to local fracture of brittle materials is currently characterized by the value of edge toughness. An “instrumented micro-edge chipping” (IMEC) is proposed and tested. WebThe necessity of preparing chip resistance test panels which very closely duplicate the actual finish obtained on cars was shown. The nature of chipping has been studied and improved rating systems developed. Detailed drawings, test procedures, and rating systems for the SAE gravelometer have been proposed for publication. ...
