Glassy deposits mainly comprising of calcium–magnesium–alumina–silicate (CMAS) accelerate the spallation thermal barrier coatings (TBCs). In this work, an Al2O3 layer was produced on yttria-stabilized zirconia (YSZ) coating by plasma spray–physical vapor deposition (PS–PVD). The effects processing parameters during PS–PVD process microstructures deposited were investigated. A homogeneous with p...

The thickness and the morphology of dip-coated single sol-gel layers is easily controlled by varying the sol compositions and the deposition parameters. A thorough study of the microstructure of transparent conducting ZnO:Al coatings deposited on fused silica substrates using X-ray diffraction, X-ray reflectometry and transmission electron microscopy cross-sections as well as of In2O3:Sn, SnO2:...

Physical Vapor Deposition (PVD) is a widely utilized process in various industrial applications, serving as protective and hard coating. However, its presence fields like fashion has only recently emerged, electroplating processes had previously dominated this reality. The future looks toward the replacement of most hazardous toxic electrochemical processes, especially those involving Cr(VI) cy...

Fretting is a surface-degradation process due to mechanical and chemical attack by small-amplitude oscillatory movement between two contacting surfaces and it is intimately related to wear, corrosion and fatigue. The introduction of surface treatments or coatings is expected to be an effective strategy against fretting damage. This paper discusses the application of several types of advanced su...

The study evaluated antioxidant status in patients with peripheral vascular disease (PVD), with and without concomitant diabetes mellitus (DM). 211 participants were divided into standardized 4 groups: patients with PVD and DM (PVD+DM+), patients with PVD without DM (PVD+DM-), patients without PVD with DM (PVD-DM+) and patients without PVD and DM (PVD-DM-). The diagnosis of PVD was established ...
