“…Then, the current density variation is one order magnitude lower for oxidized AISI 316L specimens compared to blank specimens. Our results are in accordance with the literature which shows that preoxidation of the AISI 316L improves its aqueous corrosion resistance for biomedical applications [19][20][21][22][23][24][25][26][27][28][29][30][31][32]. In this case the objective is to avoid the hexavalent chromium release from the AISI 316L stainless steel implants [33].…”

“…However, in situ X-ray diffraction (XRD) studies have never been performed on AISI 316L specimens at 800°C in order to check if a change in the structural composition of the layer appears with time and if oxide phase transitions occur during cooling to room temperature as it was demonstrated on a AISI 304 substrate [18]. From the literature, it appears that pre-oxidation of the AISI 316L SS has been tested in order to improve its aqueous corrosion resistance [19][20][21][22][23][24]. A general corrosion improvement of this material was also obtained for biomedical applications [25][26][27][28][29][30][31][32].…”

In situ X-ray diffraction was used to identify the oxides formed on the AISI 316L (containing 2% Mo) stainless steel during isothermal oxidation at 800°C, in air. Good oxidation behavior was observed on this steel when considering kinetics, structural characteristics and scale adherence. It was demonstrated that molybdenum plays a protective role in that it hinders the outward iron diffusion and leads to the lower growth rate and the better scale adherence. The oxide scale was then composed of Cr 2 O 3 with a small amount of Mn 1,5 Cr 1,5 O 4 at the external interface. Pre-oxidation of the AISI 316L also improved its aqueous corrosion resistance. No pitting corrosion occured during the corrosion test. Aqueous corrosion testing also showed that the oxide scale formed at 800°C is crack-free and still adherent after cooling to room temperature.

“…For both types of powder, there is higher oxygen content than in the standard metal, but this is not unexpected because stainless steel is known to spontaneously produce a thin surface layer of chromium-rich oxides in atmosphere. 22 The presence of such a layer is supported by the fact that surface levels of chromium are also higher than the literature and powder manufacturer's levels for 316L steel. Surface levels of oxygen and carbon are higher for the shavings.…”

This article investigates the role that particle size and morphology have in determining the final characteristics of a part produced by direct laser deposition. 316L stainless steel in the form of traditional gas-atomised powder and metal shavings in two size ranges were deposited into multiple-layer thin-walled parts at different process parameters. The walls were characterised, considering properties such as geometry, microstructure, composition, physical and corrosive properties and results matched to the type of build material. Results showed that using particles of .150 mm, equivalent spherical diameter offered few functional advantages, leading to a process with lower deposition efficiency and part with lower mechanical properties. Using machined shavings increases deposition efficiency and can reduce gas porosity compared with powder in the same size range, but also results in higher surface oxidation, thought to be due to higher oxidation on the original shavings. This is a barrier for some applications, but the deposition of machined shavings offers significant economic advantages.

“…In this respect, the effect of martensite phase on decreasing corrosion resistance of stainless steel has been reported. [74][75][76] Based on these considerations, the low corrosion resistance and high HER catalytic activity of alloy II can be attributed to the high V f of the martensite phase in its microstructure, image (b), as compared with alloy I (that with low V f of the martensite phase, image (a)). Moreover, the particle size of the g phase in CoNiGaAl alloy is much smaller than that of the same phase in CoNiGa alloy.…”

The electrochemical and corrosion behaviour of Co 50 Ni 23 Ga 27Àx Al x (x ¼ 0 and 1.0 wt%) magnetic shape memory alloys (MSMAs) was studied in 0.5 M NaCl solutions using various electrochemical techniques.Results showed remarkable activation of the tested MSMA toward pitting corrosion upon alloying it with Al. XPS examination confirmed the activation influence of alloyed Al. It proved that the presence of Al in the alloy's matrix weakens its passivity, as manifested by a lower amount of gallium oxides and Cl and FE $ 100%). Our best catalyst also showed good stability and durability after 3000 cycles of cathodic polarization between the corrosion potential (E corr ) and À1.0 V vs. RHE, and 24 h of electrolysis at a high cathodic current density of 100 mA cm À2. Microstructure changes made by Al, together with findings obtained from SEM/EDX mapping and XPS studies, were used to interpret its activation influence towards the HER.
