Tribocorrosion-resistant biofunctionalized Ti-Al2O3 composites

Influence of Calcium Acetate Concentration in Electrolyte on Tribocorrosion Behaviour of MAO Treated Titanium

“…Due to repeated material transfer between the mating surfaces, wear debris also tends to oxidize (Figure 5d) and increase its hardness. These mechanisms are typically observed for Ti surfaces tested under similar conditions [14,15,32]. For MAO-treated groups, it was observed that the outer porous MAO layers were almost completely removed in the centre of the wear track, where no elemental Ca or P from these layers was detected (Z2 in Figure 5b,c).…”

“…Due to repeated material transfer between the mating surfaces, wear debris also tends to oxidize (Figure 5d) and increase its hardness. These mechanisms are typically observed for Ti surfaces tested under similar conditions [14,15,32]. An SEM/EDS analysis of the worn sample and counter-body surfaces is presented in Figure 5.…”

“…Over the years, many studies have reported on the corrosive and biological behaviours of these layers with promising results. Regarding corrosion behaviour, studies show that oxide layers obtained by MAO confer about a one to two decade decrease in corrosion kinetics compared to their Ti or Ti alloy base materials, together with a substantial increase in corrosion potential [7,[13][14][15][16]. On the other hand, biological behaviour studies have shown that MAO layers can have improved cell adhesion, proliferation, and differentiation, as well as antimicrobial properties [4,6,7,[17][18][19][20][21].…”

Analyzing the corrosion and tribocorrosion performances of monolayer TiO2 and bilayer TiO2-SiO2 coatings at different SBF temperatures

“…In the literature, oxide-based coatings are frequently used to improve the corrosion, tribocorrosion, and wear resistance of Cp-Ti material [17][18][19] . When the literature is examined, it is noticed that the TiO 2 structure is used in many protective coating studies [20][21][22].…”

Removal Mechanism and Electrochemical Milling of (TiB+TiC)/TC4 Composites

“…Continuous low-density, high-modulus reinforcement long fibers or uniformly distributed high-strength reinforcement particles (TiB [ 9 ], TiC [ 10 ], Graphene [ 11 ], SiC [ 12 ], and Al 2 O 3 [ 13 ]) were added to the titanium alloy matrix to strengthen its wear resistance, heat resistance, elastic modulus, and other physical properties, generating titanium matrix composites (TMCs) [ 14 ]. Compared to titanium alloys, titanium composites used in aircraft engines can significantly increase the operating temperature, thereby increasing the engine thrust-to-weight ratio [ 15 ].…”
