“…The highlighted areas showed the formation of pits on the surface, suggesting a non-homogenous coating with defects, as some regions were attacked and others remained protected. This result suggested that the coating might not be best used as a surface treatment by itself, but due to its morphology, as seen in Figures 2 and 3, it could be used in conjunction with other surface treatments (Ferreira et al , 2022).…”

“…The corrosion resistance of aluminium in aqueous solutions is attributed to a passive layer of alumina (Al2O3) on its surface. However, when aluminium alloys are subjected to an aggressive environment, the passive film is broken, initiating a localised corrosion process [2,3]. The 7081-T73511 aluminium alloy have already been studied by the present authors, namely in what concerns their global and localised corrosion processes and fatigue life (air, pre-corroded and salt-water fog conditions).…”

“…As mentioned by Ayerdi [10], the method of obtaining the wear volume of ASTM G133 [6] has some limitations. ASTM G133 standard [9] disregards the rounded areas of the wear track, also known as motion reversal points [11] (See Figure 3).…”

“…Although titanium alloys exhibit good biological and corrosive properties, their usage is limited to load bearing applications due to their poor tribological characteristics [2]. Research regarding the development and application of niobium pentoxide (Nb 2 O 5 ) thin films on the titanium, aluminium and stainless-steel alloys has been performed by this research group in the last years [3][4][5][6][7][8]. Despite these excellent results, there is a lack of research that considers the effect of Nb 2 O 5 thin films on the wear properties of the Ti-6Al-4V alloy.…”
