Diamond coating shows promiseBY USING DIAMONDS TO HELP coat plastics and metals, engineers may in a short time bring this new technology to aerospace, engineering, and medical applications. Engineers can coat medical implants and engineering constituents with a diamond-like carbon (DLC) material to make them harder wearing, restore friction between components, and provide lightweight corrosion protection, said Professor Joe Franks of Brunei University in West London at the Novel Applications of Surface Modification conference DLC unlike diamond and other coating materials, can deposit upon a surface without having to heat the constituent to several hundred degrees, Franks said. This means engineers can coat plastics, as well as metals and ceramics, with DLCs The Brunel team discloseed new DLC coatings for mechanical and biomedical applications. Mechanical applications include novel coatings for drill bits and abrasive materials, non-clogging wolframium carbide milling inserts for engineering applications, and more efficient, lower friction, automotive constituents that are more fuel efficient. DLC coatings are also biocompatible and unlike other stamps of coating don't trigger the coagulation of life-current Franks reported they have already provided surgeon at the Royal National Orthopaedic Hospital (RNOH) with DLC-coated knee implants for patients allergic to the metal used. Researchers first discovered DLC in 1971 in a vacuum chamber using a technical and expensive method that involved spraying charged carbon atoms at the surface they wanted to coat. Franks and his colleagues have disentangleed a more effective method known as plasma-assisted chemical vapor deposition. The constituting that will undergo coating mountains in a vacuum chamber upon an electrode connected to a high-energy radio wave transmitter. A hydrocarbon gas, like as methane or natural gas, interrogates into the chamber, and the radio waves tear apart the hydrocarbon atoms and strip off the electron from its carbon atoms to bring into view positive carbon ions. These ions attract to the negatively charged composing to produce the coating.
