TiZrTaAg alloy is a remarkable material with exceptional properties, making it a unique choice among various industrial applications. In the present study, two types of bioactive coatings using MAPLE were obtained on a TiZrTaAg substrate. The base coating consisted in a mixture of chitosan and bioglass in which zinc oxide and graphene oxide were added. The samples were characterized in-depth through a varied choice of methods to provide a more complete picture of the two types of bioactive coating. The analysis included Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), ellipsometry, and micro-Raman. The Vickers hardness test was used to determine the hardness of the films and the penetration depth. Film adhesion forces were determined using atomic force microscopy (AFM). The corrosion rate was highlighted by polarization curves and by using electrochemical impedance spectroscopy (EIS). The performed tests revealed that the composite coatings improve the properties of the TiZrTaAg alloy, making them feasible for future use as scaffold materials or in implantology.

Nickel‐based alloys exhibit excellent mechanical properties, but the corrosion resistance when exposed to NaCl solution needs to be improved, thus limiting their widespread applications. In this study, it is demonstrated that a moderate addition of boron, specifically 3.5 wt%, can effectively enhance both the tribological properties and corrosion resistance of Ni‐based alloys. The microstructures evolution and corrosion mechanism of Ni–Cu–xB (0–5 wt%) alloys have been comprehensively investigated through the experimental characterization and phase diagram calculations. The improvements in corrosion resistance can be primarily attributed to the formation of continuous and dense passivation films. Additionally, the dissolved B fixes chloride ions to hinder the breakdown of passivation films. However, an excessive addition of boron can have a detrimental effect on corrosion resistance. While improving the formation of dense passivation films, the excessive presence of boron also prompts the precipitation of a Cu‐rich phase that is highly susceptible to corrosion by chloride ions, thereby exacerbating the corrosion process in the alloy.
