چکیده
In the present work, 5 wt.% and 10 yttria-stabilized zirconia (YSZ) nanoparticles were reinforced in Ni-20Cr powder deposited on boiler tube steel using a high-velocity oxy-fuel spraying process. The effect of YSZ reinforcement microhardness, surface roughness porosity was investigated. hardness highest for nanocomposite coating with found to increase decrease porosity. microstructure elements characterized field emission scanning electron microscopy (FE-SEM) an energy dispersive spectroscope (EDS). constituents identified X-ray diffractometer. It that composite has range 1008-1055 hv. During process, nano particles dispersed gaps between micrometric particles, providing better matrix than conventional Ni-20Cr. showed results terms mechanical microstructural properties during investigation.

WEAR REESISTANCE OF NANOSTRUCTURED AND CONVENTIONAL YTTRIA-STABILIZED ZIRCONIA COATINGS
Partially stabilized zirconia (PSZ) has been proven to be an excellent candidate as a thermal barrier coating (TBe) for hot sections in, for instance, heat or internal combustion engines and gas turbine parts. The main functions of these coatings are reducing heat losses, reducing fuel consumption, increasing efficiency, and extending durability and life. One of the main problems involved is we...
متن کاملMorphology and thermal conductivity of yttria-stabilized zirconia coatings
An electron beam directed vapor deposition method was used to grow 7 wt.% Y2O3–ZrO2 (7YSZ) coatings and the effects of substrate rotation upon the coating porosity, morphology, texture, and thermal conductivity were explored. As the rotation rate was increased, the texture changed from Æ111æ to Æ100æ. Under stationary deposition, the coatings were composed of straight columns, while low-frequen...
متن کاملOptical properties of transparent nanocrystalline yttria stabilized zirconia
The optical properties of transparent nanocrystalline zirconia produced using a current activated method were characterized over the entire visible spectrum. The resolutions of the samples were characterized using standard resolution targets. All of the samples produced were found to have as high a resolution as detectable from the test, i.e., they are transparent not translucent. Transmission,...
متن کاملDielectric properties of ionic conductors : Yttria stabilized zirconia and forsterite
— Two ionic conductors : yttria stabilized zirconia and nonstoichiometric forsterite were studied by an impedance complex method. For both materials, this technique allows us to separate, on each side of a caracteristic frequency wc, two domains corresponding to different relaxation mechanisms. The frequency a>c has been identified as the jump frequency of the charge carriers. The frequency dep...
متن کاملEffect of ion implantation doping on electrical properties of yttria-stabilized zirconia thin films
The change in conductivity of Fe and Ti implanted if-sputtered layers of yttria-stabilized zirconia (YSZ) was studied as a function of the temperature (400-800 °C) and oxygen partial pressure. In an oxidized state and in the temperature range of 400600 ° C, the conductivity of the Fe implanted YSZ film ( 15 keV, 8 × 10 '6 at.cm 2) was dominated by the n-type electronic conductivity of a thin Fe...
