Growth Behavior of Coatings Formed by Vapor Phase Aluminizing Using Fe-Al Pellets of Varying Composition

Growth of coatings on nanoparticles by photoinduced chemical vapor deposition

Photoinduced chemical vapor deposition was used to grow organic coatings on NaCl nanoparticles. Aerosolized nanoparticles were mixed with a vapor-phase coating reactant and introduced into a room-temperature, atmospheric-pressure cell, where the mixture was exposed to 172-nm radiation from a Xe2* excimer lamp. Several coating reactants were investigated; the most successful was methyl methacryl...

an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...

Growth of CNTs over Fe–Co/Nanometric TiO2 Catalyst by CVD: The Effects of Catalyst Composition and Growth Temperature

   In this research carbon nanotubes were produced by chemical vapor deposition of acetylene over a mixture of iron and cobalt catalysts supported on nanometric TiO2 and the influences of two synthesis parameters: growth temperature and catalyst composition ratio on properties of end-product carbon nanotubes were investigated. The catalytic basis was prepared by wet impregnation ...

Analysis of Al-2p photoelectron spectra of alumina coatings formed on heat treated Al-containing alloys

THE EFFECTS OF PLASMA SPRAY PARAMETERS ON THE MICROSTRUCTURE AND PHASE COMPOSITION OF THERMAL BARRIER COATINGS MADE BY SPPS PROCESS

In this paper the effect of plasma spray parameters, atomizing gas and substrate preheat temperature on microstructure and phase composition of YSZ coatings produced by SPPS process have been investigated. The experimental results showed that increasing the power of plasma, using hydrogen as the precursor atomizing gas and increasing substrate preheat temperature decrease the amount of non-pyro...
