“…The cross-sections of the coatings, illustrated in Figure 2 d–f, display a dense columnar growth pattern typical of ceramic coatings such as TiN. However, this growth pattern is interrupted by the presence of molten material droplets that are expelled from the cathode and become embedded in the coating, resulting in the formation of pinholes [ 22 , 35 , 38 , 40 ].…”

This study focused on investigating the adhesion and tribological properties of niobium-doped titanium nitride (TiNbN) coatings deposited on D2 steel substrates at various substrate temperatures (Ts) under simulated cutting conditions. X-ray diffraction confirmed the presence of coatings with an FCC crystalline structure, where Nb substitutes Ti atoms in the TiN lattice. With increasing Ts, the lattice parameter decreased, and the crystallite material transitioned from flat-like to spherical shapes. Nanoindentation tests revealed an increase in hardness (H) with Ts, while a decrease in the elastic modulus (E) resulted in an improved elastic strain limit for failure (H/E) and plastic deformation resistance (H3/E2), thereby enhancing stiffness and contact elasticity. Adhesion analysis showed critical loads of ~50 N at Ts of 200 and 400 °C, and ~38 N at Ts of 600 °C. Cohesive failures were associated with lateral cracking, while adhesive failures were attributed to chipping spallation. The tribological behavior was evaluated using a pin-on-disk test, which indicated an increase in friction coefficients with Ts, although they remained lower than those of the substrate. Friction and wear were influenced by the surface morphology, facilitating the formation of abrasive particles. However, the absence of coating detachment in the wear tracks suggested that the films were capable of withstanding the load and wear.

“…The conversion coatings fabricated by this method presented good adhesion strength in the scratch test. In other studies, the adhesion strength of different coatings such as HA coating by plasma spray and electrophoretically deposition, [31,32] TiO 2 by micro-arc oxidation [33] and TiN by PECVD [34] showed adhesive strengths less than 20 N according to scratch tests. In comparison with these results, the adhesion of the PCC formed on Ti in this research is strong enough for biomedical applications.…”

Chemically formed phosphate conversion coatings (PCC) usually have good adhesion strength due to in situ growth and have great potential for biomedical applications. However, the fabrication of PCC on titanium (Ti) metals has seldom been studied because inherent chemical inertia and oxide layer block the dissolving process. Previously, the authors successfully fabricate intact PCC on pure Ti by a novel hydrothermal phosphorization method, and the coating shows good adhesion. However, metallographically polished specimens are used only in order to eliminate the influences of surface topography. In this study, the feasibility of such method to be performed on sandpaper polished and acid‐etched pure Ti are studied. Results show that rough surface benefit the nucleation of PCC and refine the crystal size, whereas, a smooth surface allow sufficient growth of crystal grain resulting in a thicker coating with stronger adhesive strength. In spite of rough surface, PCC formation on acid‐etched Ti is depressed due to the existence of titanium hydride. All the coatings obviously improve corrosion resistance of Ti substrate. The cytotoxicity test suggests that the PCCs present no adverse effects on L‐929 cells and has a cytotoxicity ranking of 0–I grade. The study shows that the hydrothermal zinc phosphorization has a potential to be extensively used for Ti‐based implants with different surface finishes.

“…It has been shown consistently that traditional machining method has been ine cient and cumbersome in the manufacturing of a material with high strength and high temperature resistance capacity (Rizwee et al, 1807;Rizwee et al, 2020;Singaravel et al, 2020;Boopathi, 2022). Ti-13Zr-13Nb is a titanium alloy very suitable for bone implant (Shah et al, 2017;Majchrowicz et al, 2019;Ossowska et al, 2020;Kumar et al, 2021) and its fabrication quite demanding compared to other materials because of its mechanical strength and the required complex shape for biomedical implant. Electrical discharge machining method (EDM) has replaced the traditional method in the manufacturing of a complex shape and high strength material due to its high manufacturing e ciency (Zia et al, 2019;Myilsamy & Sampath, 2021).…”

Optimization of the manufacturing conditions with more than one performance characteristics have been a thing of concern, especially for Response Surface Method (RSM) optimization. Hence, this study addressed this challenge by reanalyzing a data presented in a previous study using grey relational analysis (GRA) and regression analysis. Central Composite Design (CCD) of RSM with high and low values of manufacturing conditions; voltage (50, 70) V, current (8, 16) A, pulse ON time (6, 10) μs, and pulse OFF time (7, 11) μs. The manufacturing conditions for optimal biomedical Ti-13Zr-13Nb alloy were obtained to be 50V voltage, 8A current, 6 μs pulse ON time, and 11 μs pulse OFF time. It was also revealed that the mathematical model was very efficient because the modeled GRG was in consonant with the experimental one. In addition, it was also established that current was the most significant manufacturing condition with a contribution of 47.27%. Voltage, factors interactions and residual error were insignificant on the GRG value of the titanium alloy. In conclusion, it can be deduced that the a small value of voltage within the considered settings could be used to manufacture better grade Ti-13Zr-13Nb alloy and also the small value of residual error showed the high manufacturability of the material.
