  • Patent number: 6057011
    Abstract: A high temperature and highly corrosive resistant structure and method of fabricating the structure. In one embodiment of the present invention, vacuum plasma spray or other materials deposition techniques are used to fabricate the structure on a removable support member in the form of a gradient or composite structure that sequentially consists of a 100% ceramic interior layer, a first transition layer of ceramic/refractory metal, a layer of 100% refractory metal, a second transition layer of ceramic/refractory metal, and an outer layer of 100% ceramic material. In a second embodiment, the ceramic/refractory metal/ceramic cartridge is formed without transition layers between the ceramic and metal layers. In another embodiment of the invention the structure is fabricated on a removable support member by depositing an outer layer of ceramic material on a refractory metal. No transition layers of ceramic material/refractory metals are used.
