PURPOSE: An article coated with a low-friction film useful for magnetic tapes, prepared by forming, on an article, a durable, fluorine and silicon-containing plasma-polymerized film which strongly adheres to the surface of the article serving as a base without causing any change in its characteristic properties and natures. n CONSTITUTION: The titled article is obtained by forming a film comprising a plasma-polymerized polymer containing silicon and fluorine on the surface of an article. The above polymer is formed by plasma-polymerizing a compound containing silicon and fluorine (e.g., tetrafluorosilicon) or a gaseous mixture of an organosilicon compound (e.g., tetramethylsilane) with an organofluorine compound (e.g., tetrafluoroethylene). Illustrating an example of the production process with reference to a schematic view of a high-frequency discharge plasma polymerizer, a polymerization vessel R is supplied with a gas from a monomer gas source 1 and a gas from a carrier gas source 2 which are premixed in a mixer 5. An article to be treated is supplied between rolls 9 and 10 and lies between electrodes 7 and 7'. n COPYRIGHT: (C)1984,JPO&Japio |
