Sartwell, B D

The adhesion strength and failure modes of IBAD TiN coatings were examined using a Revetest acoustic emission scratch tester. It was found that the adhesion strength which is represented as a critical normal load and failure modes of coated system are influenced by coating thickness, coating and substrate material properties, and ratio of incident argon ions to titanium atoms. The critical load increased with increasing substrate hardness. For coatings of thicknesses 0.5, 2.0, and 5.0 micrometers and with R = 0.4, the highest critical load was obtained for the intermediate thickness coating. For coatings of thickness 2 micrometers and with R values of 0.1, 0.4, and 0.7, the highest critical loads were correlated with the spallation of the coating. Further, the change in slope of the coeffient of friction of the diamond stylus sliding on the coated system could be correlated with the removal of the coating from the scratch track. A hot stage for high temperature wear tests on the Revetest apparatus has been completed and tests have been initiated.
