“…The obtained results prove the excellent corrosion resistance of the tested biomaterials in environments containing chlorides, which can be proposed for the production of long-term implants. Compared to conventional steel biomaterials, the Ti–13Zr–13Nb alloy, both before and after anodizing, shows exceptional electrochemical properties in PBS solution [ 42 ]. An anodic behavior study of different types of stainless steel in PBS solution revealed that drastically lower breakdown potential (E bd ) values were observed.…”

“…The surface zeta potential for the non-anodized and anodized Ti–13Zr–13Nb alloy was measured in aqueous electrolytes with different ionic strengths. The following solutions were applied: KCl (0.001 mol L −1 ) as the background electrolyte, PBS (0.001 mol L −l and 0.01 mol L −l ) [ 42 ] and artificial blood (0.01 mol L −l ) [ 43 ] in a wide pH range from over 3 to 9 at 37(2) °C. The pH of these aqueous electrolytes was adjusted with 0.05 mol L −1 HCl and 0.05 mol L −l NaOH, respectively.…”

“…In vitro corrosion resistance measurements of the non-anodized Ti–13Zr–13Nb alloy with 2G ONTs layers were conducted in PBS at 37(2) °C using the method of open circuit potential (OCP) and anodic polarization curves. For the preparation of PBS containing 8.0 g L −1 NaCl, 0.2 g L −1 KCl, 1.42 g L −1 Na 2 HPO 4 and 0.24 g L −1 KH 2 PO 4 [ 42 ] analytically pure reagents (Avantor Performance Materials Poland S.A., Gliwice, Poland) and Milli-Q water were used. The pH of the PBS solution was adjusted to 7.4(1) using 4% NaOH and 1% C 3 H 6 O 3 .…”

Surface charge and in vitro corrosion resistance are some of the key parameters characterizing biomaterials in the interaction of the implant with the biological environment. Hence, this work investigates the in vitro bioelectrochemical behavior of newly developed oxide nanotubes (ONTs) layers of second-generation (2G) on a Ti–13Zr–13Nb alloy. The 2G ONTs were produced by anodization in 1 M (NH4)2SO4 solution with 2 wt.% of NH4F. The physical and chemical properties of the obtained bamboo-inspired 2G ONTs were characterized using scanning electron microscopy with field emission and energy dispersive spectroscopy. Zeta potential measurements for the examined materials were carried out using an electrokinetic analyzer in aqueous electrolytes of potassium chloride, phosphate-buffered saline and artificial blood. It was found that the electrolyte type and the ionic strength affect the bioelectrochemical properties of 2G ONTs layers. Open circuit potential and anodic polarization curve results proved the influence of anodizing on the improvement of in vitro corrosion resistance of the Ti–13Zr–13Nb alloy in PBS solution. The anodizing conditions used can be proposed for the production of long-term implants, which are not susceptible to pitting corrosion up to 9.4 V.

“…The corrosion resistance of austenitic stainless steels depends on the presence of alloying elements that enhance the stability of the passive film and the absence of those that diminish it. As mentioned in [2], the superior corrosion resistance of austenitic stainless steels can be attributed to the formation of a chromium oxide-hydroxide enriched passive layer, with a thickness ranging from 0.5 nm to 5 nm, when exposed to oxygen. This passive layer exhibits self-healing properties [3][4][5][6][7].…”

Heat treatments of AISI 316L samples were conducted at 900°C with slow cooling in air to induce varied precipitation of chromium-rich carbide particles at grain boundaries, resulting in a microstructure susceptible to intergranular corrosion. The corrosion behavior of the material in this state was investigated in a salt spray chamber containing 5% NaCl. The temperature inside the chamber was set at 35°C, while the saturated air temperature was recorded at 47°C. Samples were periodically extracted for observation and analysis using a stereoscopic magnifying glass, optical microscope, and scanning electron microscope. The results revealed the detrimental effect of chloride ions on the corrosion behavior of these stainless steels. Metallographic examination of corroded specimens after the salt spray test confirmed that the passive layer's breakdown was responsible for the intergranular corrosion occurring along preferential paths of chromium carbides.

“…Also, its cost can be considered low compared to other resistant materials 3 . These characteristics make this material a usual option in manufacturing surgical devices, such as prostheses, bone fixation, syringes, medical scissors, tweezers, and scalpels [4][5][6] . Its corrosion resistance is mainly associated with the formation of a thin passive film of oxide on the steel surface.…”

This work aims to determine the best substrate preparation and conversion coatings that may enhance the anti-corrosive performance of alumina film/stainless steel substrate systems in Ringer's solution. Boehmite, silica, silica/boehmite, and boehmite/silica conversion coatings were deposited on sanded or sandblasted 304L stainless steel samples, and the best results were further covered with alumina film for a long-time exposure evaluation. The best anti-corrosive performances for each substrate preparation were observed for the sandblasted sample covered with silica/boehmite conversion coating (JSB500) and the sanded sample covered with silica (LS500), which showed the highest global resistance (R g ) values (828 Ω.cm 2 and 1837 Ω.cm 2 , respectively) and the smallest values of global capacitance, C g (2.19 X 10 -6 F.cm -2 and 3.37 X 10 -9 F.cm -2 , respectively). After covering with the alumina film and evaluating for 216 h in the corrosive medium, it was noted an increase in the R g values for both systems (JSBA500 and LSBA500), likely due to the presence of a corrosion products layer. The presence of iron oxides in these conversion coatings led to a more stable alumina film. Comparing the selected coating systems, the LSBA500 exhibited an improved performance, reaching an increase of 85% in R g and a decrease of 94% in C g .
