“…37 The deposition of MWNCTs on titanium caused about a 10% decrease under dry conditions, but even a 90% decrease in SBF (simulated body uid), 14 and a moderate change in wear volume from 14.14 × 10 6 to 10.6 × 10 6 mm 3 was found aer adding CNTs to TiO 2 in the sprayedmade coating. 32 A decreasing current density was noticed for the CNT-Hap coating from 0.54 to 0.05 mA cm −2 at 1 wt% CNTs. 22 On the contrary, aer adding MWCNTs to HAp-Ta 2 O coating, corrosion current density increased from 0.011 to 0.021 mA cm −2 .…”

“…Comparative exploration of the tribological properties of TiO 2 -CNT and TiO 2 coatings was carried out using constant load scratch tests. 143 Then, the ability of TiO 2 and TiO 2 -CNT coatings for resisting scratch damage was compared using the micro-scratch method. Eqn (12) can be used as a wear model for evaluating the scratching and anti-scratch performance ( W R ) of ceramic coatings, 144 as follows: where H V and K IC are the micro-hardness and fracture toughness of the coating, respectively, F n is the normal load, L is the sliding distance, and ∝ is the proportional relationship.…”

“…CNTs have been recognized as an ideal reinforcement for alumina composites because of their excellent mechanical and electrical properties [1][2][3]; however, the excellent properties of CNTs cannot guarantee that the reinforced alumina composites will achieve the expected performance. The main reason is that interfacial characteristics have important effects on the mechanical properties of CNTs and their reinforced composites [4,5]. In CNT-reinforced composites, CNTs are easily pinned in the grain interiors.…”
