Abstract
A supersonic, direct-current arcjet is designed for expansion into low pressure, the arcjet operates as mixtures of hydrogen and argon to convert molecular hydrogen to atomic hydrogen and direct the atomic hydrogen to a substrate surface. A hydrocarbon (methane or acetylene) is introduced in the arcjet plume where it is converted to hydrocarbon precursors and is directed to the substrate surface where it combines with the atomic hydrogen to produce a diamond film.
