“…Due to its lower cost compared to titanium and cobalt-based alloys and ease of manufacturing in combination with relatively high corrosion resistance, AISI 316L stainless steel soon became one of the most commercially available biomaterials for implant manufacturing [7,8]. However, its lower resistance to some forms of localized corrosion, such as pitting and crevice corrosion, led to its gradual replacement with higher corrosion-resistant materials including duplex steel [9][10][11][12].…”

“…Results in several published papers have shown similar biocompatibility of austenitic and austenitic-ferritic steel. The replacement of austenitic stainless steel with austenitic-ferritic in orthodontic treatments reduces costs and nickel hypersensitivity in patients [9][10][11][12][13][14].…”

“…The high corrosion resistance of austenitic stainless steels is due to the formation of 0.5 nm to 5 nm chromium oxide-hydroxide enriched passive layer in the presence of oxygen, which has self-healing properties [15][16][17][18][19]. Some authors suggested that the formed layer has a complex spinel-type passive structure which can be described as (Fe,Ni)O(Fe,Cr) 2 O 3 [10,20]. Other authors claimed that the oxide film formed on stainless steel has a bi-layer type, with the inner layer mainly composed of chromium(III) oxide with a minor presence of oxidized iron, while the outer layer consists mainly of iron oxides and hydroxides [18,21,22].…”

Anodic and spontaneous corrosion of different types of stainless steel (AISI 304L, AISI 316L and 2205 DSS) in phosphate-buffered saline solution (PBS, pH = 7.4) at 37 °C (i.e., in simulated physiological solution in the human body) were examined using open circuit potential measurements, linear and cyclic polarization, and electrochemical impedance spectroscopy methods. After the anodic and spontaneous corrosion, the surface of the tested samples was investigated by light and scanning electron microscopy (SEM) with EDS analysis. It has been established that the tendency of the examined steel materials towards local corrosion decreases in the order: AISI 304L < AISI 316L < 2205 DSS. Namely, the possibility of repassivation and the resistance to local corrosion increases in the same order. The corrosion resistance of steel samples at open circuit potential is a consequence of forming a natural oxide film with a bi-layer structure and consists of an inner barrier and an outer porous film. The inner barrier film has a small thickness and extremely high resistance, while the outer porous film is much thicker but also has significantly lower resistance. The inner barrier layer mainly prevents corrosion of examined steel samples in order: AISI 304L < AISI 316L < 2205 DSS. Light microscopy and SEM/EDS analysis after pitting and spontaneous corrosion showed damage on the AISI 304L and AISI 316L surface, while the surface of 2205 DSS was almost undamaged by corrosion.

“…Several steel alloys have been assembled to meet diverse application requirements permitting their integration into an infrastructure in all atmospheres; for example, corrosion resistant austenitic steels are used in aquatic environment, chemical industry, construction, medical and surgical instruments [20,21]. Superhydrophobic and Superhydrophilic TiO2/epoxy coatings were formed with TiO2 and fluoroalkylsilane functionalized TiO2 nanoparticles deposited on AISI 316L steel alloy and produced the durable surface [22].…”

Redundant deposits formation on steel through interaction with liquids is an integral problem that results the reduction in function and durability. Here, we report a new method to form a modifier-free durable superhydrophobic and highly anti-corrosive surface by one-step electrodeposition method. Surface morphologies, chemical composition and wettability characterized by field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), energy dispersive Xray spectroscopy (EDS), laser Raman spectroscopy (LRS), Fourier transform infrared spectroscopy (FT-IR) and optical contact angle measurements, respectively. The highest average water contact angle (CA) 167.7 ± 2.4° on fabricated surface achieved numerically and experimentally. The phase-field simulation for transient evolution of water droplet performed for superhydrophobic surface revealed that the rate of contact angle increase is greater at beginning and smaller at the equilibrium state. Superwetting surfaces exhibit enhancement of corrosion resistance based on electrochemical impedance spectroscopy, Tafel polarization curves and shear abrasion tests with excellent mechanical durability. Furthermore, the characteristics of as-fabricated mechanically durable and the stabilization of chemicals on the surface were observed.This work gives a new pathway to attain chemically and mechanically stable, ecofriendly, and corrosive-resistant superhydrophobic coating with low surface energy hydrophobicity index (βs = -0.937) on steel 316L and should have a reassuring future in increasing range of industrial applications.
