“…The deposition of coatings on steel allows an improvement in its properties such as hardness and resistance to corrosion, wear and fatigue, among others, in comparison with bulk austenitic stainless steels [9][10][11]. Stainless steel-based coatings deposited by means of the sputtering technique have been characterized in different investigations.…”

This paper presents a study of the tribological properties of stainless steel coatings with varying Ag contents, deposited via magnetron sputtering. The growth of the coatings was done in Ar and Ar + N2 atmospheres in order to change the crystalline phase in the coating. The analysis of the chemical composition was performed using energy-dispersive X-ray spectroscopy (EDS) and the structural analysis was performed via X-ray diffraction (XRD). The adhesive wear resistance and the friction coefficient were evaluated using the ball-on-disk test with a ball of alumina. The coatings’ adhesion was measured with a scratch tester and the mechanical properties were evaluated with a nanoindenter. The morphology of the films and the wear track were characterized via scanning electron microscopy (SEM). By means of XRD, phases corresponding to the body-centred cubic (BCC) structure were found for the coatings deposited in an inert atmosphere and face-centred cubic (FCC) for those deposited in a reactive atmosphere. A more compact morphology was observed in coatings with a higher silver content. The values of the hardness increased with an increase in the silver content and the presence of nitrogen in the coatings. In the wear traces, mainly mechanisms of oxidative and adhesive wear and plastic deformation were found. The coefficient of friction decreased with an increase of silver in the coatings, whereas the wear rate decreased.

“…Nickel content plays an important role in the stability of austenitic structure at high temperatures hence highnickel alloys provide good resistance to a wide variety of corrosive media and improves the physical and mechanical properties of stainless steel [7][8][9]. Manganese because of having lower cost is a good candidate to replace nickel as an austenite stabilizing element [10][11][12][13][14][15]. Manganese also increases the solubility of nitrogen [16].…”

AISI 316L-type stainless steel was coated with 300-nm-thick Mn thin films and post-annealed at 673 K with a constant flow of oxygen (250 cm 3 /min). The films crystallographic and morphological structures were analyzed using X-ray diffraction (XRD) and atomic force microscopy (AFM) before corrosion test and scanning electron microscopy (SEM) after corrosion test. Corrosion behavior of the samples in 0.3, 0.5 and 0.6 M NaCl solutions was investigated by means of potentiodynamic and electrochemical impedance spectroscopy (EIS) techniques. Results showed that the corrosion inhibition of annealed Mn/SS316L in all NaCl solutions with different concentrations is higher than that of bare SS316L. A correlation is achieved between the structural variation of the films with the potentiodynamic and EIS corrosion results.

“…While the data in Figure 3 shows some scatter, two trends can be noted: first, the c/a ratios tend to increase with deposition temperature, and second, lower c/a ratios are generally obtained for higher Ti (and nitrogen) concentrations in the films. XRD results presented in the work by Kappaganthu and Sun [25] similarly showed that the degree of lattice distortion in deposited stainless steel/nitrogen films was reduced with increased nitrogen content, and when near stoichiometric nitrogen levels were reached an undistorted fcc lattice was obtained. In that case, higher nitrogen contents in the films were obtained by increasing the N-partial pressure in the sputtering gas (75% N, 25% Ar), whereas in our case the nitrogen was increased by alloying the films with Ti.…”

“…As an alternative to plasma-based methods for nitriding stainless steels, reactive magnetron sputtering can be used to deposit N-enriched "stainless steel-nitride (SSN)" films [21][22][23][24][25][26][27][28]. Results have shown that S-phase structured films with hardness levels similar to plasma nitrided samples can be obtained [28].…”

This study examines the structure and properties of stainless steel coatings deposited to incorporate large concentrations of nitrogen along with varying amounts of titanium. Deposition was carried out using magnetron co-sputtering of stainless steel and titanium from separate targets in a mixed Ar/N2 gas atmosphere. Composition analysis by X-ray photoelectron spectroscopy showed that while films with up to 4 at.% Ti exhibited little change in nitrogen content (compared to films deposited without Ti) and remained sub-stoichiometric with respect to N content. Films with 7–8 at.% Ti had a higher N level and further increasing the Ti level to 11–12 at.% resulted in stoichiometric N levels. X-ray diffraction showed that the films all had a nominally FCC structure with no additional phases. However, the peak locations for the (111) and (200) reflections indicated a distorted lattice characteristic of the S-phase, with calculated c/a values ranging from 1.007 to 1.033. The Ti additions, along with the corresponding increase in N content, helped reduce the extent of lattice distortion. The film microstructure of the higher (11–12 at.%) Ti films also showed higher density, lower surface roughness, and a finer grain structure. As a result, these films had a higher hardness compared to the sub-stoichiometric films, with hardness levels in the range of 18–23 GPa, typical of transition metal nitrides coatings.
