Sažetak
Objective of this study is to determine the effect of indentation load on the Vickers hardness of cold isostatically pressed (CIP) high purity alumina (Al2O3) ceramics. Specimen of a CIP-Al2O3 ceramics was embedded in DuroFix-2 Kit, polished, then indented at loads ranging between 0.1, 0.2 and 0.5 kg with a Vickers hardness tester (n=30 per load). This study show that conventional hardness measurements are load-dependent, which implies a substantial influence of the indentation size effect (ISE). The ISE was described through the application of the Mayer Law, a proportional specimen resistance (PSR) model and a modified PSR model.
