Tribological coatings made of MoS2 and WSe2 phases their corresponding combinations with tungsten carbide (WC) were prepared by non-reactive magnetron sputtering individual targets similar composition. A comparative tribological analysis these multiphase was done in both ambient air (30–40% relative humidity, RH) dry nitrogen (RH<7%) environments using the same tribometer testing conditions. nanostructural study advanced transmission electron microscopy initial examination counterfaces after...
Silica multi-layer stacks have been designed with the aim to provide broadband antireflective (AR) properties for glass components in concentrated photovoltaic (CPV) application. porous coatings were grown by combining acid-catalyzed sol-gel route and evaporation induced self-assembly (EISA) method four types of organic/inorganic systems. Sols prepared using tetraethylorthosilicate (TEOS) as inorganic precursor assembled two di-block copolymers, one tri-block copolymer cationic surfactant...
Surfaces loaded with microbes can contribute to the propagation of a wide variety pathogens. In this work, antimicrobial potential hard coating (CrN) doped different proportions biocide element (copper) has been studied. The coatings have deposited by reactive high power impulse magnetron sputtering (HiPIMS) technology, on stainless steel and glass, materials used profusely in human traffic environments. microstructural mechanical properties evaluated, their antiviral (VSV-G) antibacterial...
Nanocrystalline chromium nitride and ternary aluminium thin films were deposited by reactive magnetron sputtering of Cr Al targets in argon/nitrogen atmosphere varying the power gas composition. The coatings characterized terms crystal phase, chemical composition, microstructure, mechanical properties x-ray diffraction, photoelectron spectroscopy, including x-ray-induced Auger electron transmission microscopy, selected-area energy-loss cross-sectional scanning ultramicrohardness tester....
Diamond like carbon (DLC) coatings typically present good self-lubricating tribological properties that could be of interest in sliding dielectric contacts multiple electrical applications. In this work electro-tribological studies have been performed on several DLC against aluminum different humidity conditions, which the coefficients friction (CoFs) and contact resistance (ECR) were continuously monitored. Results show CoF ECR data can linked to (thickness, finishing, microstructure,...
Preventing microbiological surface contamination in public spaces is nowadays of high priority. The proliferation a microbial infection may arise through air, water, or direct contact with infected surfaces. Chemical sanitization one the most effective approaches to avoid microorganisms. However, extended chemicals for cleaning purposes such as chlorine, hydrogen peroxide ethanol lead long-term diseases well drowsiness respiratory issues, not mention environmental issues associated their...
Composite coatings made of nanocrystalline TiC (nc-TiC) particles and amorphous carbon (a-C) have been prepared in a double magnetron sputtering system using graphite titanium targets under Ar bombardment. Chemical composition microstructure were studied by transmission electron microscopy (TEM), energy loss spectroscopy (EELS), x-ray diffraction (XRD) for set samples varying the ratio intensity power applied to each magnetron. Changes microstructure, from quasipolycrystalline nanocomposite...
Abstract Protective nanocomposite coatings based on hard ceramic phases (TiC, TiB 2 ) combined with amorphous carbon (a-C) are of interest because their adequate balance between mechanical and tribological performances. In this work, Ti–B–C were prepared by co-sputtering graphite targets. Varying the discharge power ratio applied to targets from 0 2, a-C content in could be tuned 60%, as observed means Raman x-ray photoelectron spectroscopy (XPS). The microstructural characterization...
