“…The OCP curves become stable in a short time. As stated in the literature, when the open circuit potential reaches equilibrium, it indicates that the film formation and dissolution on the surface are in balance [59]. In all OCP curves, there was first a slight movement towards the anodic side and then the curves became stable.…”

In this study, Fe-Mo-B-based hardfacing electrodes containing different amounts of Mo were coated on an AISI 1020 steel substrate using the electric arc welding method. The findings show that molybdenum is highly effective on the microstructure and minor changes in the coating composition affect the phases and morphological properties. In the hardness tests, an increase of 73% was achieved in the Fe14Mo2B4-based hardfacing coating, compared to the base material, and a 30% increase was achieved, compared to the Fe16B4-based coating. The highest hardness value was measured as 56.4 HRC and the highest phase hardness was measured as 3228 HV in the FeMo2B4 phase. The lowest wear rate was measured in the Fe14Mo2B4-based coating. The wear rate of the Fe14Mo2B4-based coating was 8.1 times lower than that of the substrate material and 4.7 times lower than that of the Fe16B4-based coating. According to corrosion test results, the highest corrosion resistance was obtained in the Fe16B4-based coating. The current density value of the Fe16B4-based coating was measured to be 13.6 times lower than that of the substrate material.

“…Oxide's color is produced during the involvement of shining rays sent back from metal beneath; as a result, color highly relied on film thickness [38]. Titanium elements are often constructed without any corroding allowance because of the strong passive layers [37]. Uniform corroding happens in reducing circumstances, especially in the acidic medium at elevated temperatures.…”

Titanium and its alloys offer numerous advantages in diverse industrial applications, but the rising demand necessitates a comprehensive understanding and prevention of corrosion failure. Corrosion, caused by electrochemical reactions with the environment, can compromise the appearance, functionality, and safety of these materials. To address this, it is crucial to investigate factors influencing their corrosion behavior, including composition, microstructure, surface treatment, environmental conditions, and mechanical loading. Beyond industrial use, titanium's biocompatibility, corrosion resistance, and mechanical properties make it widely employed in biomedical applications. Its ability to form complexes with ligands enhances biological interactions, showing promise in anticancer agents, bone implants, drug delivery, biosensors, and bioimaging probes. This review aims to provide insights into corrosion mechanisms, prevention methods for titanium and its alloys in industrial settings, and recent advancements in their diverse biological applications.

“…Moreover, the excellent biocompatibility of titanium alloys is a crucial factor for their use as biomedical implants. Common β-stabilizing elements possess outstanding corrosion resistance, such as Nb, Zr, Ta, and Mo [11][12][13][14]. Incorporating these elements into titanium alloys can enhance the stability of the passivation layer, preventing excessive release of metal ions from biomedical implants during clinical applications.…”

In this study, a series of Ti–5Cr–xNb alloys with varying Nb content (ranging from 1 to 40 wt.%) were investigated to assess their suitability as implant materials. Comprehensive analyses were conducted, including phase analysis, microscopy examination, mechanical testing, and corrosion resistance evaluation. The results revealed significant structural alterations attributed to Nb addition, notably suppressing the formation of the ω phase and transitioning from α’ + β + ω to single β phase structures. Moreover, the incorporation of Nb markedly improved the alloys’ plastic deformation ability and reduced their elastic modulus. In particular, the Ti–5Cr–25Nb alloy demonstrated high values in corrosion potential and polarization resistance, signifying exceptional corrosion resistance. This alloy also displayed high bending strength (approximately 1500 MPa), a low elastic modulus (approximately 80 GPa), and outstanding elastic recovery and plastic deformation capabilities. These aggregate outcomes indicate the promising potential of the β-phase Ti–5Cr–25Nb alloy for applications in orthopedic and dental implants.
