چکیده

Plasma-based ion implantation (PBII) is usually carried out with isotropic gaseous plasmas, such as a discharge in nitrogen. More recently, it has been applied using drifting plasmas, such as those produced by cathodic arcs, in order to allow efficient implantation of metallic species. The condensable nature of a cathodic arc plasma allows for the deposition of ion-stitched thin film coatings, as well as surface modification by ion implantation. In this paper the promising results for biomaterial fabrication are discussed in light of current limitations of the technique. The use of PBII to control preferred orientation in titanium nitride films is also discussed, together with implications for the physical mechanisms involved in the development of preferred orientations in thin films. 2002 Elsevier Science B.V.

Tailored SERS substrates obtained with cathodic arc plasma ion implantation of gold nanoparticles into a polymer matrix.

This manuscript reports on the fabrication of plasmonic substrates using cathodic arc plasma ion implantation, in addition to their performance as SERS substrates. The technique allows for the incorporation of a wide layer of metallic nanoparticles into a polymer matrix, such as PMMA. The ability to pattern different structures using the PMMA matrix is one of the main advantages of the fabricat...

Blood Compatibility of Titanium-Based Coatings Prepared by Metal Plasma Immersion Ion Implantation and Deposition

In this work the suitability of some Tibased coatings as coating for blood-contacting implants is analyzed. Layers of pure Ti, Ti nitride, Ti oxynitrides (TiN1-xOx with x = 0.25, 0.50, and 0.75) and Ti oxides were deposited from a plasma produced by cathodic arc evaporation under addition of N2 and/or O2. The oxynitrides are crystalline with the fcc structure of TiN up to x = 0.25. For x = 0.5 ...

Bias and Self-Bias of Magnetic Macroparticle Filters for Cathodic Arc Plasmas

Curved magnetic filters are often used for the removal of macroparticles from cathodic arc plasmas. This study addresses the need to further reduce losses and improving plasma throughput. The central figure of merit is the system coefficient, κ , defined as filtered ion current normalized by the plasma-producing arc current. The coefficient κ is investigated as a function of continuous and puls...
