Microstructure of Metallorganic Chemical Vapor Deposited Aluminum Coatings on Ti6242 Titanium Alloy

Comparison of Properties of Ti/TiN/TiCN/TiAlN Film Deposited by Cathodic Arc Physical Vapor and Plasma-assisted Chemical Vapor Deposition on Custom 450 Steel Substrates

This study investigated the effects of deposition techniques on the microstructural and tribological properties of Ti/TiN/TiCN/TiAlN multilayer coatings onto a Custom 450 steel substrate. The coatings were produced using cathodic arc physical vapor deposition (CAPVD) and plasma-assisted chemical vapor deposition (PACVD). The microstructural of the coatings was evaluated using (SEM), and phase f...

Determination of Optical Properties in Germanium Carbon Coatings Deposited by Plasma Enhanced Chemical Vapor Deposition

In this research, Germanium-carbon coatings were deposited on ZnS substrates by plasma enhanced chemical vapor deposition (PECVD) using GeH4 and CH4 precursors. Optical parameters of the Ge1-xCx coating such as refractive index, Absorption coefficient, extinction coefficient and band gap were measured by the Swanepoel method based on the transmittance spectrum. The results showed that the refra...

Study of GaN:Eu3+ Thin Films Deposited by Metallorganic Vapor-Phase Epitaxy

Using metallorganic vapor-phase epitaxy, thin films of gallium nitride activated by Eu3+ GaN:Eu3+ have been deposited on sapphire substrates at atmospheric pressure. Luminescence from Eu3+ ions in GaN has been investigated using photoluminescence PL and PL excitation spectroscopy. Experimental results show that Eu3+ ions are excited via energy transfer from the host. Analyses of the observed em...
