Diamond deposition on hardmetal substrates – Comparison of substrate pre-treatments and industrial applications

Growth dynamics of nanocrystalline diamond films produced by microwave plasma enhanced chemical vapor deposition in methane/hydrogen/air mixture: Scaling analysis of surface morphology

“…Diamond and diamond films have attracted increasing interest for tribological, electrical, optical, thermal and biomedical applications [1][2][3] due to a unique combination of material properties including high hardness, chemical inertness, high thermo-conductivity, etc. The high roughness of microcrystalline diamond (MCD) films is a main obstacle to use this type of diamond films for applications where the roughness needs to be minimal.…”

Nanostructured Coatings in Micromoulding Injection – A Case Study

“…The geometrical change is minimal and the surface layer may have properties covering an extremely wide range, from hard diamond and ceramic coatings to very soft polymeric or lamella-structured films [4]. CVD-diamond deposition has been available since 1982 and because of diamonds high hardness and wear resistance, tool applications were immediately investigated, because it can significantly prolong the lifetime of tools used in cutting and milling of non-ferrous materials, such as Al(Si) alloys, graphite, and plastics [5]. Nanocrystalline diamond has attracted a great deal of both experimental and theoretical interest over the past few years, having various potential applications as ultrathin, ultrahard coatings, nanocomposites, nanobearings, materials for field emission displays, Micro-Electro-Mechanical Systems (MEMS) and surface acoustic wave devices (SAW) to electrochemical electrodes and electron emitters [6,7].…”

Analytical TEM study of CVD diamond growth on TiO2 sol–gel layers

“…The mechanism for formation of the carbon clusters is probably related to diffusion of carbon species into the TiO 2 layer during the plasma treatment process. Carbon diffusion and saturation processes are generally believed the most crucial stages for diamond nucleation [29,30]. Some authors claim that the enhancement of diamond nucleation densities is due to the formation of carbonaceous overlayer "stocks" on top of the substrate surface under their experimental conditions [31].…”
