    摘要: A shield (2) restricts the circulation of a metal bearing gas around the platform surface (8) of a turbine blade (1) so that the gas deposits a thinner coating on the platform surface (8) than on the airfoil surface (6), whereby the coating is thick enough to provide desired corrosion and oxidation resistant properties for the airfoil surface (6), but is thin enough to prevent the platform surface (8), where stress forces are greatest, from becoming too brittle. The shield (12) may be modified to cover only the high pressure side of the platform surface (8).

    摘要: According to the present invention, an apparatus (10) for applying material by cathodic arc vapor deposition to a substrate (12) is provided which includes a vessel (14), apparatus (16) for maintaining a vacuum in the vessel, an annular cathode (18) having a bore (46) and an evaporative surface (44) extending between first (40) and second (42) end surfaces, apparatus (24) for selectively sustaining an arc of electrical energy between the cathode and a anode, and apparatus for driving the arc around the evaporative surface. The apparatus for driving the arc is positioned within the cathode bore, and produces a magnetic field that runs substantially parallel to the evaporative surface. The annular cathode is disposed radially inside of, and aligned with, the substrates inside the vessel.
