Abstract: A method of treating a surface of an extensible hydrocarbon article by positioning the article in a chamber from which extraneous oxidizing agents are excluded, extending the article, and treating the extended surface with a fluorinating gas which may contain elemental fluorine or a mixture of same with an inert gas such as nitrogen. The treatment provides improved frictional characteristics, chemical inertness, and other desirable properties.
