Titanium-based nitride physical vapour deposition (PVD) coatings, such as titanium (TiN), are state-of-the-art solutions for surface modifications of CoCrMo-based implants patients who hypersensitive to metallic ions cobalt, chromium and nickel. Variations the process parameters during cathodic arc evaporation known exhibit an impact on properties coatings. The aim this study was characterise e...

Industrial upscaling frequently results in a different coating microstructure than the laboratory prototypes presented literature. Here, we investigate wear behavior of physical vapor deposited (PVD) MoS2 coatings: A dense, nanocrystalline coating, and porous, prismatic-textured coating. Transmission electron microscopy (TEM) investigations before after testing evidence crystallographic reorien...

Abstract Plasma spray-physical vapor deposition (PS-PVD) as a novel process was used to prepare feather-like columnar thermal barrier coatings (TBCs). This special microstructure shows good strain tolerance and non-line-of-sight (NLOS) deposition, giving great potential application in aero-engine. However, due serious service environment of aero-engine, particle erosion performance is weakness ...

PVD (physical vapor deposition) and CVD (chemical have gained greater significance in the last two decades with mandatory shift from electrodeposition processes to clean deposition due environmental, public safety, health concerns. Due frequent use of coatings several industrial sectors, importance studying chromium coating through PVD–sputtering can be realized, investing a real alternative el...

AIMS To identify variations in posterior vitreous detachment (PVD) and establish a clinical classification system for PVD. METHODS 400 consecutive eyes were examined using biomicroscopy and vitreous photography and classified the PVD variations-complete PVD with collapse, complete PVD without collapse, partial PVD with thickened posterior vitreous cortex (TPVC), or partial PVD without TPVC. ...
