“…As it is evidenced in the polarization curves, the passive film protects the steel samples even after having soaked in the medium for 7 days and then breaks down at a higher potential value than the before‐soaking sample. Over the breakdown potential, the passive film enters the transpassive region where the current density increases due to the pitting attack on the metal surface 30 . Soaking of samples in the medium for 1 week did not significantly affect the breakdown potential of the steel, but there was a difference in the passivation current density between the before‐ and after‐soaking samples.…”

“…So, the anodic passivation potential domain extends to the breakdown potential. On the other side, the passive current density is defined as the minimum current density necessary to maintain the film in the passive domain, and the breakdown of the passive film of the stainless steel is commonly due to pitting corrosion 29–31 . Therefore, the more positive the value of the breakdown potential is, the higher the resistance against pitting corrosion is.…”

“…Thus, we can admit that, during the soaking period of the steel in α‐MEM for 7 days at 37°C, Ca 2+ and H 2 PO 4 − /HPO 4 2− ions present in the medium were adsorbed or precipitated on goethite, and further, the stainless steel surfaces were covered by agglomerated and dispersed particles of goethite and Ca‐PO 4 precipitates. Regarding Na element, the chromium diffusing from the mass of steel can react with sodium and dissolved oxygen to produce Na–Cr–O/Na–Fe–O species, whereas the chloride element in its ionic form Cl − is known to adsorb easily on the surface of 316L stainless steel 30 …”

The use of 316L stainless steel as an orthopedic bone plate material or as a substrate for coating implies the need to study its properties in a biological medium simulating human body environment. Therefore, the aim of this work is to investigate the microstructural characteristics, corrosion resistance, and mechanical properties of 316L stainless steel in the culture medium and then to check the cytotoxicity of the stainless steel in the presence of human mesenchymal stem cells. The characteristics of the stainless steel were evaluated by studying the microstructure of the samples in untreated state and after soaking in minimum essential medium‐alpha (α‐MEM) for 7 days. The results indicated the formation on the surface of the 316L stainless steel of goethite and deposits composed of Ca and P with porous and amorphous structures, which led to the decrease in the elastic modulus and the hardness of the soaked stainless steel as shown by nanoindentation test. Nevertheless, the hardness and the elastic modulus of the steel after soaking were influenced only for a surface depth of approximately 0.1% of the thickness of the sample. The potentiodynamic polarization curves exhibited that the corrosion resistance of the soaked stainless steel was reduced because of the higher passive current density. However, it should be noticed that the breakdown potential of the steel after soaking was slightly higher, leading to a wider range of passivation. In addition, microscopy examination showed the mesenchymal stem cell adhesion on the materials after 9 days of culture.

“…It is known that stainless steel usually suffers from pitting corrosion in NaCl medium, and, according to Hou et al [31], who studied pitting corrosion in Cl − -containing medium at different temperatures for the pitting in 316 L stainless steels, the proposed equivalent circuit describes a system for non-coated steels with resistance against pitting corrosion due to passive-formed layers. The equivalent circuit elements are Re, which represents the electrolite resistance; R f , which represents the material's oxide film resistance, which is strongly dependent on the properties of the passivating layer; and R pit , which represents the charge transfer resistance on the surface, which is normally associated with the formation of pits [31]. Because R pit occurs at lower frequency values, this value has a stronger influence on the total system impedance; therefore, the higher the R pit value, the lower the corrosion rate and the better the corrosion resistance.…”

The aim of this work was to evaluate the porosity, microstructure, hardness, and electrochemical behavior of AISI 316 steel layers deposited on an AISI 347 steel substrate using the LMD process. Depositions of two, four, and six layers with a 0.5 mm height for each layer were performed at a speed of 375 mm/min, a power of 250 W, a focal distance of 5 mm, and without overlapping laser tracks. The results showed epitaxial growth of the deposited layers in relation to the substrate and a predominantly austenitic microstructure with ferrite as the substrate. The deposited layers presented a dendritic microstructure with a mean porosity of 4.5%. The porosity decreased as the number of deposited layers increased, affecting the pitting corrosion resistance. The sample with six deposited layers showed greater pitting corrosion resistance, whereas the corrosion current speeds were similar for the studied samples. Vickers hardness tests showed that the hardness decreased as the distance from the substrate increased, and the hardness decreased close to the remelted regions.

“…The relationship between corrosion behavior and environmental temperature is an essential topic in the study of stainless steel. Hou et al [ 28 ] considered that the passive film resistance of 316L SS in methyl diethanolamine solution dropped as the solution temperature rose. Cui et al [ 29 ] established that temperature caused a decrease in the protection of passive properties in 2507 super duplex stainless steel by altering the doping concentrations and structure.…”

In this work, the influence of temperature on the corrosion behavior of AlCoCrFeNi2.1 eutectic high-entropy alloy in a chloride-containing sulfuric acid solution was investigated using electrochemical measurement, X-ray photoelectron spectroscopy, and scanning electron microscopy. Results show that the passive film of AlCoCrFeNi2.1 is stable in chloride-containing sulfuric acid solutions at low temperatures, while an unstable film forms on the alloy at high temperatures. Furthermore, temperature changes the proportion of hydroxide and oxide in Fe and Cr, but it has no noticeable effect on Al and Ni, which is a significant factor on the passive behavior. L12 phase exhibits good corrosion resistance at different temperatures. Pitting occurred on B2 phase in the chloride-containing sulfuric acid solution at a low temperature of 5 °C, while pitting and dissolution take place on AlCoCrFeNi2.1 in the acid solution at room temperature and above.
