Chemical Vapor Deposition of Titanium Nitride on Cemented Carbides

A Review on Titanium Nitride and Titanium Carbide Single and Multilayer Coatings Deposited by Plasma Assisted Chemical Vapor Deposition

In this paper, we reviewed researches about the titanium nitride (TiN) and titanium carbide (TiC) single and multilayer coatings. These coatings were deposited by the plasma assisted chemical vapor deposition (PACVD) technique. Plasma-based technologies are used for the processing of thin films and coatings for different applications such as automobile and aerospace parts, computer disc drives,...

Ultralight boron nitride aerogels via template-assisted chemical vapor deposition

Boron nitride (BN) aerogels are porous materials with a continuous three-dimensional network structure. They are attracting increasing attention for a wide range of applications. Here, we report the template-assisted synthesis of BN aerogels by catalyst-free, low-pressure chemical vapor deposition on graphene-carbon nanotube composite aerogels using borazine as the B and N sources with a relati...

Surface Chemical States of Heteroepitaxial Nitride Films on Sapphire by Metalorganic Chemical Vapor Deposition

Surface chemical states of GaN, AlGaN and InGaN by metalorganic chemical vapor deposition, and the influence of different dopants are studied with X-ray Photoelectron Spectroscopy (XPS). The results show that for most of the samples the N 1s peak can be fitted with a dominant GaN peak and a small N–H peak, while Ga 3d can be deconvoluted into three peaks from elemental Ga, GaN and Ga2O3. Si-dop...

Effects of Hot Isostatic Pressure on Titanium Nitride Films Deposited by Physical Vapor Deposition

Films of titanium nitride deposited by physical vapor deposition on 304 L stainless steel substrates were hot isostatic pressed (HIP) under 150 MPa at 550 °C. To study the effects of this treatment on the microstructure of those films, X-ray diffraction analyses, Rutherford Backscattering spectroscopy, scanning electron microscopy, and atomic force microscopy were performed. Surface hardness, a...
