Title:
【発明の名称】改善された複合体性質を有する炭化珪素モノフィラメント及び製造方法
Document Type and Number:
Japanese Patent JP3035595
Kind Code:
B2
Abstract:
A high strength silicon carbide monofilament which has a core and a stoichiometric bulk layer of silicon carbide deposited on the core having an exterior surface and a core bulk layer interface, the bulk layer having an average grain size of less than 200 nanometers which size varies continuously across the cross section of the bulk layer, the variation comprising a first average grain size at the interface which increases to a maximum average grain size intermediate the interface and the exterior surface and then decreases to the minimum at the exterior surface. In an alternate embodiment a surface layer is deposited on the bulk layer of silicon carbide. A preferred method of making the silicon carbide monofilament is also presented.
