Abstract
A method for the formation of tantalum carbides on a graphite substrate includes the steps of: (a) adding an organic tantalum compound, a chelating agent, a pre-polymer to an organic solvent to form a tantalum polymeric solution; (b) subjecting a graphite substrate with the tantalum polymeric solution to a curing process to form a polymeric tantalum film on the graphite substrate; and (c) subjecting the polymeric tantalum film on the graphite substrate in an oven to a pyrolytic reaction in the presence of a protective gas to obtain a protective tantalum carbide on the graphite substrate.
