“…Generally, it is known that Si is the mainly dominant diffusion species, and Si atoms as smaller atoms regarding Ti and Zr are easily diffused in their crystal lattice, locating in interstitially positions [ 45 ]. Elemental maps for Zr ( Figure 6 b2) and Ti ( Figure 6 b3) reveal that these atoms are intermixed, indicating the final result to the formation of Ti-Zr alloy due to their unlimited dissolving [ 46 , 47 ]. From the image obtained by the mutual overlap of all three elemental maps ( Figure 6 b4), it can be concluded that the degree of Ti and Zr mixing is reduced with the distance from the surface, whereby they keep a layered structure inside of the thin films.…”

Ultrafast laser processing with the formation of periodic surface nanostructures on the 15×(Ti/Zr)/Si multilayers is studied in order to the improve cell response. A novel nanocomposite structure in the form of 15×(Ti/Zr)/Si multilayer thin films, with satisfying mechanical properties and moderate biocompatibility, was deposited by ion sputtering on an Si substrate. The multilayer 15×(Ti/Zr)/Si thin films were modified by femtosecond laser pulses in air to induce the following modifications: (i) mixing of components inside of the multilayer structures, (ii) the formation of an ultrathin oxide layer at the surfaces, and (iii) surface nano-texturing with the creation of laser-induced periodic surface structure (LIPSS). The focus of this study was an examination of the novel Ti/Zr multilayer thin films in order to create a surface texture with suitable composition and structure for cell integration. Using the SEM and confocal microscopies of the laser-modified Ti/Zr surfaces with seeded cell culture (NIH 3T3 fibroblasts), it was found that cell adhesion and growth depend on the surface composition and morphological patterns. These results indicated a good proliferation of cells after two and four days with some tendency of the cell orientation along the LIPSSs.

“…In the coatings world, the nanostructures benefits were exploited successfully, enhancing performance and functionality in many domains, introducing more stability and corrosion resistance in various aggressive environments, including bioliquids. A better cell response, as well as more adhesion and better mechanical properties [134][135][136] were obtained via more green coating fabrication methods. Some multifunctional coatings that are discussed in more detail below are presented in Figure 2.…”

Starting with a description of the meaning of sustainable coating nowadays, this review presents a selection of methods for sustainable coatings manufacture using raw materials, saving energy and costs. This selection creates an introduction for the coatings performances of intensively investigated coated alloys and their multifunctionality. There are many examples and EU recommendations to be discussed, and we especially chose to introduce sustainable coatings with both industrial and medical functions, such as bioinspired films and coatings on high-entropy alloys, biodegradable metallic alloys, etc. A special focus is on nanotechnology and nanomaterials in green procedures, enhancing coatings’ multifunctionality, introducing green corrosion inhibitors, smart additives, and coatings based on superhydrophobicity. The conclusions and future perspectives of sustainable and multifunctional coatings, as expressions of sustainable advanced materials, are based on important motivations of such studies.

“…Based on a series of investigations [11][12][13][14] that were performed, it was revealed that TiZr alloys with a percentage of 50% Zr [13] present polarization curves with a larger passive range, meaning that the resistance to localized corrosion is higher compared to other TiZr binary alloys, such as Zr5Ti and Zr25Ti alloys, which were susceptible to localized corrosion [11,12]. Moreover, the TiZr alloys with 50% Zr are considered to have superior mechanical properties [8,15] along with enhanced behavior in terms of biocompatibility [9,16].…”

“…It was reported that an increase of Zr content on the surface resulted in an increase of nanohardness [ 15 ]. Such a type of surface possesses a reduced modulus of elasticity, namely 77–98 GPa, which is significantly improved compared with Ti, which has a modulus of elasticity of 110 GPa.…”

Assessing the Functional Properties of TiZr Nanotubular Structures for Biomedical Applications, through Nano-Scratch Tests and Adhesion Force Maps

In this work we present the results of a functional properties assessment via Atomic Force Microscopy (AFM)-based surface morphology, surface roughness, nano-scratch tests and adhesion force maps of TiZr-based nanotubular structures. The nanostructures have been electrochemically prepared in a glycerin + 15 vol.% H2O + 0.2 M NH4F electrolyte. The AFM topography images confirmed the successful preparation of the nanotubular coatings. The Root Mean Square (RMS) and average (Ra) roughness parameters increased after anodizing, while the mean adhesion force value decreased. The prepared nanocoatings exhibited a smaller mean scratch hardness value compared to the un-coated TiZr. However, the mean hardness (H) values of the coatings highlight their potential in having reliable mechanical resistances, which along with the significant increase of the surface roughness parameters, which could help in improving the osseointegration, and also with the important decrease of the mean adhesion force, which could lead to a reduction in bacterial adhesion, are providing the nanostructures with a great potential to be used as a better alternative for Ti implants in dentistry.
