Abstract: Chromium nitride and silicon doped chromium nitride thin films have been deposited by r.f. reactive magnetron sputtering. The effect of processing parameters on the properties of chromium nitride films and the correspondent influence of the addition of silicon on the chromium nitride matrix in the films structure and mechanical properties have been :// The remaining chloride ammonolyzes to form chromium nitride. As will be shown, these reactions are confirmed by XRD and FTIR analyses of the residual thermolysis products. Download: Download full-size image; Fig. 9. Thermogravimetric analysis of the precursor in flowing ammonia (40 cm 3 /min). The vertical lines approximately mark the thermal In this study, a nanostructured chromium nitride (CrN) thermoelectric material with a ZT value ∼, exhibiting both high mechanical reliability and thermal stability, was prepared using a simple chemical method. Its hardness, reaching GPa, is much higher than that of most other traditional thermoelectric :// The formation of stoichiometric chromium nitride can occur only at high nitrogen and extremely low oxygen partial pressures , so newly available nitrogen can interact with pure Cr at the
Comparative Study of High Temperature Oxidation Behaviour For the thermogravimetric analyses, the samples were cut with dimensions of 10 mm × 10 mm × mm. A small ble if the chromium amount is higher than a critical value given by6: Figure :// A comparative study of the oxidation behavior of Cr 2 N and CrN coatings was investigated in air at temperatures ranging from °C to °C including phase structure, surface and cross-sectional morphologies, oxidation kinetics and mechanism. During oxidation, the dense Cr 2 O 3 scales form both on the Cr 2 N and CrN coatings. The Cr 2 N phase transforms to CrN phase, which is Polysulfone nanocomposite membranes with 1% TiO 2 is found to have a higher porosity, percentage of water uptake, mechanical properties, and a lower contact angle. Polysulfone with 1% TiO 2 is found to have a higher performance with the flux rate of l/m 2 h along with the % Cr(VI) ion rejection and a better antifouling :// as halide, oxide, nitride, water, pyridine, or can remain coordinatively unsaturated, allowing for the study of a wide variety of systems and effects.

The predictions of a computer simulation for high‐drain, batteries are compared to the observed performance of four full‐size batteries: the Mk 61 (Mod 0 and Mod 2), Mk 64, and Mk The Mk 61 Mod 0, like the Mk 64 and Mk 67 batteries, uses AZ61 magnesium anodes; the Mk 61 Mod 2 uses the high‐voltage magnesium alloy, AP This study investigates the effects of the deposition process and coating composition on microstructural and tribological properties of TiN and CrN based coating systems. Coatings were produced using various PVD based processes — electron beam (EB), cathodic arc (CA) and plasma enhanced magnetron sputtering (PEMS). Below K, FeCr2O4 was found to be first reduced to iron and chromium oxide before the latter being further reduced to chromium. At higher temperatures, the reduction of Cr2O3 appeared to occur 1 day ago These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than kg/mm 2, primarily intended for applications as manufacturing tools or wear
