摘要：

Nanoindentation measurements at elevated temperatures were performed on alpha-Al2O3 and kappa-Al2O3 hard coatings at temperatures up to 600 and 700 degrees C, respectively. A reduction of the hardness and reduced modulus was observed for both coating systems although more accentuated for the kappa-Al2O3 coating. In addition, a comprehensive overview of guidelines on how to perform nanoindentation measurements on hard coatings at elevated temperatures is provided. (C) 2015 Elsevier B.V. All rights reserved.
