Patent ID: 8784565

Claim:
A manufacturing apparatus for deposition of a material on a carrier body having a first end and a second end spaced from each other with a socket disposed at each end of the carrier body, said apparatus comprising: a housing defining a chamber; an inlet defined through said housing for introducing a gas into the chamber; an outlet defined through said housing for exhausting the gas from the chamber; at least one electrode including a shaft having a first end and a second end with a head disposed on one of said ends of said shaft for coupling with the socket with said electrode having an exterior surface having a contact region adapted to contact the socket, said electrode disposed through said housing with said electrode at least partially disposed within the chamber for coupling with the socket; a power supply device coupled to said electrode for providing an electrical current to said electrode; a contact region coating disposed on said contact region of said electrode for maintaining thermal conductivity between said electrode and the socket, said contact region coating having an electrical conductivity of at least 9×10 6 Siemens/meter and corrosion resistance higher than silver in a galvanic series based upon room temperature sea water as an electrolyte; and an exterior coating different from said contact region coating and disposed on at least one of said head and said shaft outside of said contact region.
