Nickel chromium (NiCr) powders with different titanium diboride (TiB2) additions (20, 40 and 60 wt %) were prepared with a mechanical alloying method and then sprayed using an air plasma spraying technology. The microstructure and phase composite of the powders and the cross-sections of deposited coatings were analyzed with a scanning electronic microscope and X-ray diffraction. The tribologica...

Coating growth and mechanical properties of nanolamellar Cr2AlC coatings at various sputtering power were investigated in the present study. Cr2AlC coating was deposited on the IN 718 superalloy and (100) Si wafers by DC magnetron sputtering at different sputtering powers. The structure and properties were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmis...

Lanthanum strontium cobalt oxide (LSCO) has been employed as cathode and intercollector materials for solid oxide fuel cells (SOFCs). In the present study, the La0:5Sr0:5CoO3 layer was deposited by atmospheric plasma spray (APS). The effect of heat treatment on microstructure and electrical conductivity of the LSCO deposits was examined. The electrical conductivity of the deposits along the lam...

The present study investigates the significance of different coating process parameters on the corrosion behaviour of electrolessly deposited Ni-P-W coatings on mild steel substrate. The process parameters considered are concentration of nickel source, concentration of reducing agent, concentration of tungsten source and annealing temperature. The corrosion characteristic is evaluated by electr...

In this work we investigate theoretically the Landau-Levich problem of dip coating in the presence of a strong interaction potential normal to the substrate. This study is motivated by dip coating at very low capillary numbers when the deposited film thickness is less than 1 m and such interaction forces become important. The objective of this work is to demonstrate that in the presence of an e...

The liquid crystalline phase behavior of sterically-stabilized goethite particles in toluene was studied using small-angle X-ray scattering. The results were compared with those from charged particles in water, with and without magnetic field: similarly rich phase behavior was found. Furthermore, the special magnetic properties were retained after coating the particles with amino-functionalized...

XRD and EDX analyses confirmed the presence of Ag in all coatings deposited using electrochemical method and silver. The mean thickness coating was noted to be highest in EHA/AG group (102.20 4.20 um) followed by PHA (76.40 2.20 um). Mean coating thicknesses in other groups were: PHA/AgNO3 (76.20 1.29 um); EHA (32.98 2.50 um); EHA/ Ag/2-layers (30.70 2.40 um); EHA/AgNO3 (8.60 0.60 um). The aver...

The surfaces of hydoxyapatite ceramics were modified by the precipitation of octacalcium phosphate coating from aqueous solution and the biomimetic method synthesized nanohydroxyapatite coatings. Both coatings were deposited as continuous and uniform layers. It was demonstrated that the octacalcium phosphate coating was inappropriate for in-vitro osteoblast proliferation despite of good initial...

Al-Cr and Al-Cr-Si composite cathodes were obtained by the hot compaction of aluminum, chromium, silicon powder mixtures. The phase transformations in surface layer subjected to arc heating considered. elemental compositions modified cathodes’ surfaces studied using X-ray diffraction, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS). effect addition on structural evoluti...

TiO2 coatings deposited using reactive magnetron sputtering and spray coating methods, as well as Agand Mo-doped TiO2 coatings were investigated as self-cleaning surfaces for beverage processing. The mechanical resistance and retention of the photocatalytic properties of the coatings were investigated over a three-month period in three separate breweries. TiO2 coatings deposited using reactive ...
