Understanding the chemical vapor deposition of diamond: recent progress.

Recent progress in understanding the electrochemical behavior of the oxidized boron-doped diamond electrode surface

Boron-doped diamond (BDD) thin films have recently come to be considered as being among the most ideal electrode materials for electroanalysis and electrolysis. For BDD films prepared by use of the microwave plasma-assisted chemical vapor deposition (MPCVD) method, the as-deposited surfaces are hydrogen-terminated. These surfaces, however, can be oxidized while being used as anodes, i.e., at re...

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...

Effect of Catalyst on the Growth of Diamond-like Carbon by HFCVD

Diamond like carbon (DLC) film was grown by hot filament chemical vapor deposition (HFCVD)technique. In the present work, we investigated the quality of the DLC films groew on the substratesthat were coated with various metal nanocatalysts (Au and Ni). A combination of CH4/Ar/H2 rendersthe growth of carbon nanostructures technique (diamond like carbon). The utilized samples werecharacterized by...

Method for growing a diamond thin film on a substrate by plasma enhanced chemical vapor deposition

An Investigation on Two Types of Crystalline Micro-diamond Film Coated Tools Lapping with Sapphire Wafer

Two types of micron-diamond films were prepared on YG6 substrate by hot filament chemical vapor deposition(HFCVD) method. Morphology and orientation of crystalline growth were evaluated by SEM and XRD. Diamond film coated tools and sapphire wafer’ surface before and after lapping experiment  were contrasted. The results indicated that a significant change in Raman spectrum of two types of micro...
