“…To improve the corrosion behavior of austenitic stainless steels, a number of technological procedures can be applied: electropolishing [3], heat treatment [4][5][6], surface treatment, or patterning [6,7]. Heat treatments are widely used to obtain mechanical or tribological characteristics adapted to the specific requirements of medical devices [8].…”

The appropriate selection of implant materials is very important for the long-term success of the implants. A modified composition of AISI 316 stainless steel was treated using solar energy in a vertical axis solar furnace and it was subjected to a hyper-hardening treatment at a 1050 °C austenitizing temperature with a rapid cooling in cold water followed by three variants of tempering (150, 250, and 350 °C). After the heat treatment, the samples were analyzed in terms of hardness, microstructure (performed by scanning electron microscopy), and corrosion resistance. The electrochemical measurements were performed by potentiodynamic and electrochemical impedance spectroscopy in liquids that simulate biological fluids (NaCl 0.9% and Ringer’s solution). Different corrosion behaviors according to the heat treatment type have been observed and a passivation layer has formed on some of the heat-treated samples. The samples, heat-treated by immersion quenching, exhibit a significantly improved pitting corrosion resistance. The subsequent heat treatments, like tempering at 350 °C after quenching, also promote low corrosion rates. The heat treatments performed using solar energy applied on stainless steel can lead to good corrosion behavior and can be recommended as unconventional thermal processing of biocompatible materials.

“…Such a relationship between wettability and corrosion rate has been observed in micro-patterned aluminum surfaces (Ruiz de Lara et al, 2016), in which the pattern with the highest water contact angle exhibits the lowest corrosion rate. Hydrophobic surfaces repel the surrounding corrosive liquid media and thereby exhibit significant corrosion resistance (Ruiz de Lara et al, 2016;Toloei et al, 2013;Guo et al, 2016).…”

“…Alternatively, to achieve hydrophobicity, topographical modification of surfaces can also be employed, that is, by creating micro/nano-patterns (Arvind Singh et al, 2009). Patterned surfaces are promising candidates for applications such as anti-icing, self-cleaning, drag reduction, friction reduction (Arvind Singh et al, 2009) and, in recent years, are being investigated for their potential to resist corrosion (Ruiz de Lara et al, 2016;Toloei et al, 2013;Guo et al, 2016). Micro-pillar-shaped patterns on aluminum surfaces have shown excellent corrosion resistance to NaCl aqueous solution, with corrosion rates lower by one order of magnitude compared to un-patterned aluminum surface (Ruiz de Lara et al, 2016).…”

Purpose The failure of structures and components made of SS304 steel because of corrosion in the presence of saline water environment is still an unsolved issue across the globe. Conventionally, coatings and inhibitors are used to mitigate corrosion. The purpose of this study is to propose a novel method to tackle corrosion by means of micro-patterning on the surface and to explore the relation between surface morphology, corrosion and wetting nature of micro-patterned SS304 Steel. Design/methodology/approach Groove-shaped micro-patterns were created on SS304 steel surface with varying ridge and channel widths. Wettability studies conducted on flat and micro-patterned steel surfaces using high speed camera. Corrosion tests carried out in saline water using an electrochemical test set-up to quantify the performance of micro-patterned surface over flat surface and scanning electron microscopic analysis to visualize the severity of corrosion on the surfaces of SS304 steel. Findings Wettability studies showed that the micro-patterned steel surfaces were hydrophobic. Corrosion rates of the micro-patterned steel surfaces were lower by more than an order of magnitude compared to that of the flat steel surface. Scanning electron microscopic analysis revealed that the micro-patterned steel surfaces had less surface damage compared to the flat surface. Originality/value The author shows that the remarkable corrosion resistance shown by the micro-patterned steel surfaces is attributed to their hydrophobicity, which reduced the contact between the surfaces and the corrosive liquid media. Results from the investigation indicate that micro-patterning of SS304 steel surfaces is an effective route to decrease corrosion.

“…On the other hand, Liu et al [29] have shown that 316LVM steel stents coated with TiO 2 layers presented better passivation stability and antibreakdown performance than bare stents in a phosphate buffered solution. In general, the surface modification of the 316LVM stainless steel seems to be one of the solutions to improve its corrosion resistance in physiological conditions in order to be used as human implants [30,31].…”

Tantalum carbide (TaC), hafnium carbide (HfC), and Ta-Hf-C mixed coatings with and without a gold (Au) interlayer were deposited on 316LVM steel substrates by the magnetron cosputtering technique in order to improve the corrosion resistance of steel substrates in a simulated biological fluid. To study the effect of the gold interlayer on pitting corrosion, the different systems were placed in contact with Ringer’s solution at pH 7.4 and a temperature of 37°C. The electrochemical properties of the coatings were determined using polarization curves. Subsequently, the surface morphologies were observed using scanning electron microscopy (SEM) in order to analyze the corrosion processes on the different surfaces. The gold interlayer was found to significantly improve the electrochemical properties of the system, showing a decrease in the pitting corrosion and deterioration rate, while it is expected that the binary and ternary carbides provide mechanical stability to the bilayers protecting the gold.
