Abstract:
A method of deposition of Diamond-Like-Carbon on a substrate comprising the steps of:a. providing a chamber; b. positioning said substrate within said chamber; c. creating a low pressure environment within said chamber; d. applying power to an ion beam source; e. supplying a hydrocarbon-containing gas within said low pressure environment in said chamber; f. creating a hydrocarbon-containing gas environment in said low pressure environment within said chamber; g. generating an ion beam from said ion beam source as a result of said power applied to said ion beam source in said hydrocarbon-containing gas environment; h. forming a diamond-like-carbon coating on said substrate as a result of an interaction between said ion beam and said hydrocarbon-containing gas environment to create a diamond-like-carbon coated substrate, wherein said interaction between said ion beam and said hydrocarbon-containing gas environment also causes the formation of carbon-based material within said chamber; i. stopping said step of forming a diamond-like-carbon coating on said substrate; j. isolating said diamond-like-carbon coated substrate from a carbon-reactive gas environment; k. supplying a carbon-reacting gas within said low pressure environment in said chamber; l. creating said carbon-reactive gas environment in said low pressure environment within said chamber; m. causing a reaction of least some of said carbon-based material to form at least some carbon reaction product; and n. removing at least some of said carbon reaction product from said chamber.
