A cathodic arc coating apparatus for applying a coating to an object is provided. The apparatus includes: an enclosure; means for evacuating the enclosure; an anode within the enclosure, wherein the anode comprises an open array of a metal defining a central axis and a deposition space for positioning the object; a cathode assembly positioned within the deposition space, wherein the cathode assembly comprises a first consumable cathode having a central axis and an evaporation surface; means for generating a plasma stream comprising charged particles, wherein the plasma stream is projected from the evaporation surface of the first consumable cathode toward the anode array; and a magnetic system for diverting the charged particles of the plasma stream away from the anode array and toward the object being coated; wherein the diverted charged particles are deposited on the object to form a coating thereon.
摘要:
In the pursuit of the forming of light composite materials which may be substituted for metal without loss of strength, composites have been manufactured from silicon carbide fibers in a titanium matrix. Titanium diffuses into the given boundaries of the silicon carbide and degrades it. Yttria has been sandwiched between the titanium and silicon carbide, to provide a reaction skin of yttria which reduces the extent of diffusion. The present invention oxidizes the silicon carbide prior to applying the yttrium and thus further improves the resistance to diffusion.
