“…Figure 4 shows the Raman spectra of the as-deposited TaZrN and the deconvolution of the three main bands. The bands around 175 and 470 cm −1 correspond to the LA and TA, attributed to longitudinal and transversal acoustic vibrations of the heavy ions (typically of metal ions), while the band around 620 cm −1 is from the LO and TO optical vibrational modes of the lighter ions (nitrogen ions) [31,[38][39][40][41][42]. Figure 5 shows the potentiodynamic polarization curves of the TaZrN film and the TiAlV substrate.…”

Different works have demonstrated that tantalum, zirconium, and their nitrides present good biocompatibility. Additionally, TaN and ZrN possess excellent corrosion and wear resistance. Ternary nitrides such as TiAlN have been improved in terms of their mechanical properties with respect to binary systems. Therefore, ternary nitrides as TaZrN have high potential to be used in biomedical applications. This work was focused on studying the tribological and tribocorrosion performance of a TaZrN film. The coating was deposited by DC (Direct Current) magnetron sputtering in a reactive atmosphere using Ta and Zr targets. The tribological characterization was carried out in dry (atmospheric condition) and corrosive environments (synthetic body fluid). The coated surface shows better wear resistance than the uncoated in both conditions. The wear mechanism was studied by FE-SEM (Field Emission-Scanning Electron Microscopy) and Raman confocal microscopy. The wear rate of the coated surfaces was higher in corrosive ambient than in dry conditions. The observed wear mechanism was adhesive–abrasive for lower loads and abrasive at dry conditions for an applied load of 2 N. For corrosive media the principal wear mechanism for 2 N was abrasive–corrosive. For all tests at dry conditions, the formation of a tribolayer of metal oxides, graphite, and amorphous carbon was seen.

“…Following each wear test, Raman measurements were conducted on the wear debris. Raman spectroscopy is a widely used nondestructive technique for wear debris characterization [3,[12][13][14][15]. Its main advantages are simplicity of application, possibility of characterization from small quantities and also not having additional sample preparation requirements [12], The shape, width and intensity of Raman signals gives information not only of chemical nature but also on the crystallinity and structure of the debris [13].…”

The preferred growth direction of cathodic arc physical vapor deposition-produced TiN coatings changes from (1 1 1) to (2 2 0) with high voltage pulsed bias application in the presence of Ar gas. In this study, tribological properties of these coatings were investigated via reciprocating wear tests against an inert counterbody for observing the role of orientation on tribological properties. Friction coefficients and wear of (2 2 0) oriented coatings were observed to be significantly lower compared to (1 1 1) oriented coatings. Micro-Raman investigations of the wear debris formed during tribotest revealed clear differences between (1 1 1) and (2 2 0) oriented films. Wear debris obtained from (2 2 0) oriented coatings consisted of nc TiO2 phases (anatase and rutile) whereas (1 1 1) oriented coatings produced amorphous Ti oxides. This behavior is attributed to the orientation dependent oxidation kinetics of the coatings as verified with isothermal oxidation tests. A mechanism for improved tribological behavior is proposed based on the obtained results.
