Suspension plasma spraying (SPS) has become an interesting method for the production of thermal barrier coatings for gas turbine components. The development of the SPS process has led to structures with segmented vertical cracks or column-like structures that can imitate strain-tolerant air plasma spraying (APS) or electron beam physical vapor deposition (EB-PVD) coatings. Additionally, SPS coa...

Biofouling is one of the drawbacks restricting the industrial applications of membranes. In this study, different thicknesses of silver nanoparticles with proper adhesion were deposited on poly(vinylidenefluoride) (PVDF) and polyethersulfone (PES) surfaces by physical vapor deposition (PVD). The crystalline and structural properties of modified and pure membranes were investigated by carrying o...

Si and Ge have the same crystalline structure, and although Si-Au and Ge-Au binary alloys are thermodynamically similar (same phase diagram, with the eutectic temperature of about 360°C), in this study, it is proved that Si and Ge nanowires (NWs) growth by electron beam evaporation occurs in very different temperature ranges and fluence regimes. In particular, it is demonstrated that Ge growth ...

The substrate material was nickel-based superalloy (In738LC), and CoNiCrAlY was pressureless plasma-sprayed on the substrate as the bond coating. As the top coating, zirconia with 4 mol% yttria was electron beam-physical vapor deposited (EB-PVD) on the rotating substrate. The rotation speeds in the EB-PVD process were 5, 10 and 20rpm. The specimens were exposed to 1273K in air atmosphere for 20...

Understanding the physical vapor deposition (PVD) process of metallic coatings on an inorganic substrate is essential for packaging and semiconductor industry. In this work, we investigate a Copper (Cu) film glassy Calcium Aluminosilicate (CAS) by PVD its dependence incident energy. Molecular dynamics simulation adopted to mimic process, pure Cu grown top CAS surface forming intermixing region ...

High Speed Steel (HSS) specimen surfaces were coated with AlCrN and AlTiN via Physical Vapor Deposition (PVD) method. Then, the wear performances of film coatings so produced investigated by using different abrasive types particle sizes. During micro-abrasion tests, 0.5, 1 1.5 N loads applied for periods 60 180 seconds. loss increased increasing SiC Al2O3 size. Micro-grooving micro-rolling obse...

With the rising demands of industry to increase working temperature gas turbine blades and internal combustion engines, thermal barrier coatings (TBC) were found be an effective way further enhance lifetime aero components through improvement mechanical properties oxidation-resistance. Thus, this paper aims review coating technologies with special emphasis on plasma-sprayed (PS), those produced...

Abstract Organic semiconductors (OSC) are widely used for consumer electronic products owing to their attractive properties such as flexibility and low production cost. Atomically thin transition metal dichalcogenides (TMDs) another class of emerging materials with superior optical properties. Integrating them into van der Waals (vdW) heterostructures provides an opportunity harness the advanta...
