Flexible carbon seal ring with an amorphous carbon phase on its sealing.

摘要

An article comprising flexible graphite with a continuous amorphous carbon phase on a surface of the article, the amorphous carbon phase extending from the surface into the interior of the article. A method for manufacturing a flexible graphite article having a surface with an amorphous carbon phase thereupon which comprises: (a) compressing exfoliated graphite flakes into an article having a density between 0.05g/cm<3> and 2.0g/cm<3>; (b) applying an organic material upon a surface of the article; and (c) subjecting the article to a temperature sufficient to coke the hydrocarbon to form an amorphous carbon phase upon the surface of the article. r
