The adhesion of hot-filament CVD diamond films on AISI type 316 austenitic stainless steel
Steel ball indentation and scratch adhesion testing of hot filament chemical vapour deposited diamond films onto AISI type 316 austenitic stainless steel substrates using two different interlayer systems, namely chromium nitride and borided steel, have been investigated. In order to compare the adhesion of these films with that of a well-known and strongly adherent system, detailed adhesion tes...
متن کاملDeposition of Diamond Films in a Closed Hot Filament CVD System
A closed system hot filament chemical vapor deposition (CVD) reactor has been used to deposit diamond films on silicon substrates. A fixed charge of hydrogen gas is fed into the deposition system until the desired deposition pressure level is reached. A solid graphite cylindrical rod held above the tungsten filament was the carbon source. System parameters for diamond film growth have been dete...
متن کاملSynthesis of Carbon Nanotubes by Plasma Enhanced Hot-Filament C
A mixture of acetylene, hydrogen and ammonia C2H2/H2/NH3 is used to produce carbon nanotubes (CNTs) by a plasma-enhanced catalytic chemical vapor deposition process with hot-filaments assistance (PE HF CCVD). The investigation of gas phase and surface chemistry is performed by CHEMKINTM software. The concentration of gas phase species on the substrate is presented. Based on this study the role ...
متن کاملDual catalytic purpose of the tungsten filament during the synthesis of single-helix carbon microcoils by hot-wire CVD.
We report on the deposition of crystalline single-helix carbon microcoils, in the as-deposited state, by the hot-wire chemical vapor deposition process without any special preparation of nano-sized transition metal catalysts and subsequent post-deposition annealing. Tungsten, originating from the heated tungsten filament, is identified as the catalyst material responsible for the growth of the ...
متن کاملComputer Simulation of Temperature Parameter for Diamond Formation by Using Hot-Filament Chemical Vapor Deposition
To optimize the deposition parameters of diamond films, the temperature, pressure, and distance between the filament and the susceptor need to be considered. However, it is difficult to precisely measure and predict the filament and susceptor temperature in relation to the applied power in a hot filament chemical vapor deposition (HF-CVD) system. In this study, the temperature distribution insi...
