Abstract | As reported for many years, hydrogenated DLC films (a-C:H) have been a choice of a protective coatings for many applications due to their set of superior mechanical, chemical, tribological and biological properties such as: high hardness, high wear resistance, low coefficient of friction, high chemical inertness, good biocompatibility, bactericide, etc.. However, in order to improve the adhesion between the DLC and the different metals substrates a huge modification of a Pulsed DC PECVD technique has been obtained introducing an additional cathode working as electron and ion confinement. With these modifications pressure as low as 10-3 mbar allow operating in collisionless regime improving not only the adhesion but also a set of DLC proprieties cited above. So, in this work we present studies concerning more improvement properties of the DLC films as a function of confinement of electrons and ions parameters in a plasma discharge by using argon as an ignitor gas for the interlayer precursor and keeping it during all the process of DLC deposition. In this case the best conditions of collisonless operation was reached at pressure as low as 3.10-4 mbar. Basically, due to the condition of operating in very low pressure, this technique allows to grow the DLC film with very good uniformity and higher hardness, higher adhesion, lower coefficient of friction, less porosity and, also, provide to be able to get a DLC deposition in the form of multilayer, like thicker films, promoting less residual stress. So, studies at the first time, of DLC with superior properties has been carried out from PECVD technique. More specifically, studies of the DLC film properties as a function of the argon buffer gas density and as a function of bias voltage has been done. Raman scattering spectroscopy, Rockwell indentation, nano indentation, FEG, and trybological analyses are discussed. Also, the operating parameters of this modified PECVD system are well controlled, so that a scaling up studies will also be presented as an important part of this work. |
