Keywords Adhesion,Coatings, Corrosion
Many metals, ceramics, and plastics require special coatings for protection against wear and corrosion, but getting the coatings to adhere tightly can be problematic, especially thick ones. Researchers at Los Alamos National Laboratory (Los Alamos, New Mexico)have developed a method that produces highly adherent layers of common coatings such as metal oxides or nitrides, plus a diamond-like carbon coating.
The method uses a plasma that roots itself in the substrate, creating a graded coating that provides high resistance against delamination. It is more environmentally friendly than many methods currently in use and allows creation of coating-substrate combinations that are not currently feasible. The technique can be applied in the manufacturing of car parts, machine tools, prosthetics, and other devices.
