Low?Temperature Physical Vapor Deposition TiAlCrSiN Coated High?Speed Steel: Comparison Between Shot?Peened and Polished Substrate Condition

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...

Antibacterial Properties of TiAgN and ZrAgN Thin Film Coated by Physical Vapor Deposition for Medical Applications

Titanium(Ti) and zirconium(Zr) have been widely researched in the field of biomedical materials, due to their excellent mechanical properties and biocompatibility. They belong to group IVa in the periodic table, and are known to have similar chemical properties, and no toxic effects. However, they do not possess antibacterial properties. Inflammation and infection, which are usually caused by a...

Physical Vapor Deposition Simulations of Microstructure Evolution

Growth of carbon nanostructures upon stainless steel and brass by thermal chemical vapor deposition method

The lack of complete understanding of the substrate effects on carbon nanotubes (CNTs) growth poses a lot oftechnical challenges. Here, we report the direct growth of nanostructures such as the CNTs on stainless steel 304and brass substrates using thermal chemical vapor deposition (TCVD) process with C2H2 gas as carbon sourceand hydrogen as supporting gas mixed in Ar gas flow. We used an especi...

Diamond icosahedron on a TiN-coated steel substrate

Diamond layers have been deposited by hot filament chemical vapour deposition (HF CVD) on TiN-coated steel substrates. After deposition, we could observe separate, well-developed diamond icosahedrons and decahedrons on the surface. We have found that a lower content of methane in hydrogen supports their growth, this being a result of multifold twinning. The quality of diamond layers has been ev...
