Download or read book Synthesis Structure and Characterization of Silver Doped Diamond Like Carbon Thin Films written by Pankaj Jyoti Hazarika and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond like carbon (DLC) films have gained grounds in the biomedical field as an inert, biocompatible, low friction and wear resistant coating and are widely used in heart valves, coronary artery stents, dental implants, knee prosthesis and other vascular devices. In addition, Ag nanoparticles/films can prevent the formation of biofilm on biomedical implants by degrading the metabolic activities like permeability and respiration and also impair DNA replicability. Thus, Ag-doped DLC (Ag-DLC) can serve as a multifunctional bio coating combining desirable antibacterial and physical/mechanical characteristics. In the present study, Ag-DLC films were synthesized utilizing a hybrid Plasma CVD and Magnetron sputtering process in a CH4/Ar glow discharge. Nanocomposite films containing Ag nanoparticles in an amorphous DLC matrix with various amounts of Ag were synthesized and characterized by Transmission Electron Microscope (TEM), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Photoelectron Spectroscopy (XPS). Tribological experiments were performed to assess the frictional behavior and wear resistance of the Ag-DLC films as a function of Ag content. Anodic polarization experiments were conducted to characterize the electrochemical behavior of the Ag-DLC films. TEM results revealed that Ag nanoparticles of 4-7 nm in size were uniformly distributed in an amorphous DLC matrix. Microhardness of DLC films exhibited a hardness of 22 GPa and it gradually decreased with increasing Ag content in the films. Wear rate of DLC film was 1.9 x 10-8 mm3/Nm and it increased to 8 x 10-7 mm3/Nm for Ag-DLC (5% Ag) film. Electrochemical behavior experiments showed that Ag-DLC films exhibited an inert behavior compared to the pure silver.

Download or read book Comparative Surface and Nano tribological Characteristics of Nanocomposite Diamond like Carbon Thin Films Doped by Silver written by and published by . This book was released on 2008 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study we have deposited silver-containing hydrogenated and hydrogen-free diamond-like carbon (DLC) nanocomposite thin films by plasma immersion ion implantation-deposition methods. The surface and nano-tribological characteristics were studied by x-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and nano-scratching experiments. The silver doping was found to have no measurable effect on sp2-sp3 hybridization of the hydrogenated DLC matrix and only a slight effect on the hydrogen-free DLC matrix. The surface topography was analyzed by surface imaging. High- and low-order roughness determined by AFM characterization was correlated to the DLC growth mechanism and revealed the smoothing effect of silver. The nano-tribological characteristics were explained in terms of friction mechanisms and mechanical properties in correlation to the surface characteristics. It was discovered that the adhesion friction was the dominant friction mechanism; the adhesion force between the scratching tip and DLC surface was decreased by hydrogenation and increased by silver doping.

This book was released on 1990-02-01 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent discoveries enabling the growth of crystalline diamond by chemical vapor deposition offer the potential for a wide variety of new applications. This new book examines the state of the technology arising from these discoveries in relation to other allied materials, such as high-pressure diamond and cubic boron nitride. Most of the potential defense, space, and commercial applications are related to diamond's hardness, but some utilize its other qualities, such as optical and electronic properties. The authors review growth processes and discuss techniques for characterizing the resulting materials' properties. Crystalline diamond is emphasized, but other diamond-like materials (e.g. silicon carbide and amorphous carbon containing hydrogen) are also examined. In addition, the authors identify scientific, technical, and economic problems that could impede the rapid exploitation of these materials, and present recommendations covering broad areas of research and development.

Stout and published by . This book was released on 1999 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diamond-like carbon coatings produced by Plasma Source Ion Implantation (PSII) and beamline Ion Beam Assisted Deposition (IBAD) were synthesized and studied. Gas pressure and electrical current were used as variables to design four independent PSII test sets. Beamline IBAD samples were produced with a pre-optimized set of parameters. Profilometry measurements showed the films to have thicknesses between 1.44 +/- 09 and 1.64 +/- 04 microns and to possess very low roughness averages, ranging from 14 +/- 3 to 28 +/- 3 nm, which correlate with substrate surface roughness. Atomic Force Microscopy revealed that diamond-like carbon crystal sizes varied significantly with chamber pressure. Crystals were generally spherical in shape suggesting that films were highly amorphous. Microhardness and nanohardness test results showed the hardest films to be greater than 3 times the hardness of untreated steel. The elastic modulus of the films, measured during the nanohardness test, was directly related to film hardness. Fretting wear and Pin-on-Disk tests were performed to quantitatively assess the ability of films to resist wear. Fretting wear tests showed a dramatic decrease in friction for diamond-like carbon films with friction levels ranging from 10% to 30% of that of untreated steel. Pin-on-Disk tests revealed a significant improvement in wear resistance prior to stylus penetration into the substrate.
