    Abstract: A turbine blade having a leading edge portion and a flowing-off edge portion is formed using the following steps: providing a centrifugal casting device having a rotor and at least one crucible being accommodated in the rotor; providing a mold having an extended cavity for forming the turbine blade; arranging the mold so that an inlet opening of the mold is arranged with an outlet opening of the crucible, and further arranging the mold so that a mold leading edge is directed in a direction against the rotational direction of the rotor; forcing a metal melt by means of centrifugal forces from the crucible into the mold; exerting a pressure on the melt being forced into the mold until the temperature of the solidifying melt has reached a predetermined cooling-temperature; and relieving the pressure when the temperature of the solidifying melt is below the predetermined cooling-temperature.

    Abstract: A metal gasket for a semiconductor fabrication chamber capable of preventing base plate metal contamination in the chamber, wherein the metal gasket includes a diffusion barrier layer interposed between a base plate and an anti-corrosive coating layer, and wherein the diffusion barrier layer prevents elements of the base plate from being diffused to the anti-corrosive coating layer. Accordingly, the diffusion barrier layer prevents attack on the anti-corrosive coating layer.

    Abstract: Chromium nitride coating of machine components such as reciprocating pump plungers for continuous sliding contact with non-metallic packing and gasket materials greatly increases the performance life of fluid seals. In an air driven reciprocating constant pressure pump, exterior surfaces of the pump plunger are coated with chromium nitride to a thickness of seven to ten microns. The coating resists failure from repeated sliding contact against non-metallic packing and gasket materials for at least four million pump cycles, with no evidence of cracking or release of metallic particles which would embed in the packing or gasket material and score the plunger. In lower pressure pumps, interior walls of a housing against which a sliding gasket bears, when coated with chromium nitride, greatly increase the seal life of the sliding gasket.

    Abstract: A liquid pumping, handling and spraying system for liquid compositions and especially those liquid coating compositions having a suspension of metal particulate therein which tends to settle out of suspension of metal particulate therein which tends to settle out of suspension quite rapidly and which includes metal particulate having an affinity for adherence to metal surfaces. A fluid supply system is provided which accomplishes continuous agitation of the liquid composition to sprayed to maintain the metal particulate thereof in properly entrained suspension and even distribution with the liquid carrier fluid and which permits the use of low cost, lightweight containers for the liquid supply. A packingless pump is provided for pressurized delivery of the liquid composition from the supply container to a packingless spray gun. The packingless pump achieves pumping of liquid by hydro mechanical deformation of polymer variable volume pump chambers which induce intermittent suction and pressurization of the liquid for pumping and which have externally mounted check valve heads for controlling the flowing of the pumped liquid from the supply container to the spray gun. The packingless spray gun employs a body of resilient polymer which functions as a columnar spring to control the opening and closing movement of a spray valve assembly. Valve seats of the check valve head and spray gun assembly may be of flexible nature to ensure efficient separation of metal particulate therefrom. Metal operational components of the check valve head and spray gun, such as valve stems and valves define outer surfaces composed of titanium to minimize metal particulate adherence thereto.
