Coatings by physical vapor deposition (PVD) have become highly relevant due to their wide range of applications and the rapid rate coating formation. In this work, AISI steel 1045 was coated with two layers, Ni Co using PVD technique. Each deposited a thickness 1 ?m. After applying coatings, post-treatment applied in an AC plasma reactor boron nitride blank Ar atmosphere at pressure 3 Torr, 0.3...

Various PVD (physical vapor deposition) hard coatings including nitrides and metal-doped diamond-like carbons (Me-DLC) were applied in plastic injection and die-casting molds to improve wear resistance and reduce sticking. In this study, nitrides hcp-AlN (hexagonal close-packed AlN), Cr₂N, (CrAl)₂N) and Me-DLC (Si-DLC and Cr-DLC) coatings were prepared using a closed field unbalanced magnetron ...

Multilayered hard coatings with a CrN matrix and an Al2O3, TiO2, or nanolaminate-Al2O3/TiO2 sealing layer were designed by a hybrid deposition process combined with physical vapor deposition (PVD) and atomic layer deposition (ALD). The strategy was to utilize ALD thin films as pinhole-free barriers to seal the intrinsic defects to protect the CrN matrix. The influences of the different sealing ...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...

In order to further enhance tribological properties 316 Low carbon stainless steel (L SS) used on mechanical parts. CrN/TiN with DC magnetron sputtering sources was carried out on PVD 316 L SS. The micro structure of the CrN/TiN coatings were investigated by Scanning electron microscope (SEM), X-ray Diffraction (XRD) and tribology properties were investigated on a Pin on Disc friction and wear ...

The corrosion behavior of TiN coated 316L stainless steel in an artificial physiological solution was investigated by means of an electrochemical test. Two different PVD methods were used for film deposition: cathodic arc and reactive magnetron sputtering. The dependence of the corrosion resistance on the main deposition parameters (nitrogen pressure, substrate bias) was analyzed. For a better ...

a r t i c l e i n f o The adhesion of Pt to carbon surfaces is an important technological consideration in proton exchange membrane fuel cells (PEMFCs). Thin films of Au, Ti and Cr were deposited on graphite, non-hydrogenated diamond-like carbon (NH-DLC) and hydrogenated DLC (H-DLC) coatings' surfaces using a physical vapour deposition (PVD) process. The friction force curves obtained from slid...
