The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...

The corrosion protection abilities of modified copper in 2-[((Z)-1-{6- [(2-sulfanylphenyl)ethanimidoyl]-2-pyridyl}ethylidene)  amino]-1- benzenthiol solution containing TiO2 nanoparticles were evaluated by Tafel  polarization  and  impedance  spectroscopy  in  3.5%  sodium chloride  solution.  The  samples  were  characterized  by  energy dispersive  X-ray  (EDX)  and  scanning  electron  mi...

in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...

Chitosan based nanofibers containing carbon nanotubes were applied on AZ31 magnesium alloy via electrospinning. The magnesium substrate was initially anodized in a NaOH solution in order to improve the adhesion between the coating and substrate. Electrospinning parameters were optimized and homogenous nanofibers composite coatings were produced. Addition of carbon nanotubes reduced the size of ...

The main objective of this study was to prepare sustained release metformin hydrochloride microcapsules by the Wurster fluidized bed and to obtain the optimized coating process and formulation. Fine microcapsules without agglomeration were obtained in a continuous coating process with the atomization air pressure of 0.2Mpa and an appropriate coating speed temperature. With other design variable...

nanosized tio2 particles were prepared by sol–gel method. the tio2 particles were co-deposited with chromium using electrodeposition technique. in investigating of coating surfaces by scanning electron microscope (sem), the results showed that the morphology of the coating surface was changed by adding tio2 nanoparticles to the chromium coating. the corrosion behavior of the coatings was assess...
