Fig. 7

Nanomechanical properties of MAO and UMAO coatings: (a) elastic modulus (E) and hardness (H), and (b) H/E ratio values. The coatings show lower values of elastic modulus and hardness compared to the uncoated specimen. All data are expressed as means ± SD, n = 25; * ─ statistically significant difference as compared to the uncoated Ti13Zr13Nb (p < 0.05).
