Abstract

1277498 Carbon articles GULF OIL CORP 22 Sept 1969 [3 Oct 1968] 46483/69 Heading C1A An article having high strength characteristics comprises an article made of graphite or a refractory material having a coefficient of thermal expansion between 6 to 9 Î 10<SP>-6</SP>/‹ C. having a coating of pyrolytic carbon surrounding it, said pyrolytic carbon being deposited at atmospheric pressure and at a temp. of at least 1200‹ C. such that the deposited carbon has a density of at least 1À5 g./c.c., its coefficient of thermal expansion being less than that of the substrate material so that as a result of the thermal contraction occurring during the cooling of the coated article from deposition to ambient temperature the pyrolytic coating is placed under compressive stress. Preferably the compressive stress is at least 5000 p.s.i. and the thickness of the carbon coating is at least 25 microns. The pyrolytic carbon deposit may be isotropic, or laminar and may have an apparent crystallite size not greater than 50 Š. Isotropic carbon is defined as that which possesses very little preferred orientation, has a broad range of apparent crystallite size, a density varying from 1À4 to 2À2 g./c.c. and a structure which when viewed metallographically under polarized light is not optically active. Laminar carbon is defined as that carbon possessing layer planes orientated parallel to the substrate surface, also having various apparent crystallite sizes, a density ranging from 1À5 to 2À2 g./c.c. and a structure which when viewed metallographically under polarized light is optically active showing a typically "cross-pattern". The isotropic carbon deposit may have a Bacon Anisotropy Factor of not greater than 1À1. The deposited carbon may have a carbide, e.g. silicon carbide, dispersed throughout. The carbide may be produced by introducing a carbide forming material, e.g. a volatile Si compound, into the atmosphere of carbonaceous gas and inert gas used to to deposit the coating. The deposition temperature is preferably between 1200‹ and 1500‹ C.
