“…The crystal structure of the coated ceramic films was determined by X-ray diffraction (XRD) using aB ruker D4 endeavor diffractometer applying Cu Ka (l = 1.54 )r adiation. To minimize disturbing signals caused by the aluminum substrate, the measurements were performed with the grazing incidence method (38)with adiffraction angle of 108 to 908.…”

“…In this work, we report the surface modification of the Al current collector by ceramic coating with chromium nitride (Cr x N) as well as the electrochemical characterization of the anodic dissolution behavior. In general, the Cr–N binary system is characterized by the presence of two intermediate phases, Cr 2 N and CrN, in the solid state . By utilizing the physical method of magnetron sputter deposition, two different coating types were prepared and characterized regarding their structure, electronic conductivity, and surface properties.…”

Batteries based on cathode materials that operate at high cathode potentials, such as LiNi Mn O (LNMO), in lithium-ion batteries or graphitic carbons in dual-ion batteries suffer from anodic dissolution of the aluminum (Al) current collector in organic solvent-based electrolytes based on imide salts, such as lithium bis(trifluoromethanesulfonyl) imide (LiTFSI). In this work, we developed a protective surface modification for the Al current collector by applying ceramic coatings of chromium nitride (Cr N) and studied the anodic Al dissolution behavior. By magnetron sputter deposition, two different coating types, which differ in their composition according to the CrN and Cr N phases, were prepared and characterized by X-ray diffraction, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and their electronic conductivity. Furthermore, the anodic dissolution behavior was studied by cyclic voltammetry and chronocoulometry measurements in two different electrolyte mixtures, that is, LiTFSI in ethyl methyl sulfone and LiTFSI in ethylene carbonate/dimethyl carbonate 1:1 (by weight). These measurements showed a remarkably reduced current density or cumulative charge during the charge process, indicating an improved anodic stability of the protected Al current collector. The coating surfaces after electrochemical treatment were characterized by means of SEM and XPS, and the presence or lack of pit formation, as well as electrolyte degradation products could be well correlated to the electrochemical results.

The heat treatments of Ni-free SUS445 stainless steel under nitrogen and argon gas atmospheres were conducted at 1373-1473 K in the present study. The heat-treated samples were characterized by an X-ray diffraction (XRD), glow discharge optical emission spectroscopy (GD-OES), and scanning electron microscopy (SEM) equipped with energy-dispersive X-ray spectroscopy (EDX). The corrosion behavior of the heat-treated samples was evaluated by linear sweep voltammetry (LSV) measurements in a 0.5 mol dm −3 H 2 SO 4 solution. The results revealed that the nitrided stainless steel at 1373 K presents the best corrosion resistance and the AlN, expanded austenite γ N , CrN and Cr 2 N phases appeared based on the XRD results. In contrast, the corrosion resistance of the heat-treated stainless steel under an argon atmosphere was decreased and there was no change in the microstructure.
