Abstract: A method for forming an exterior surface of a high-temperature component, such as a blade or vane of a gas turbine engine. The method entails forming a shell by a powder metallurgy technique that yields an airfoil whose composition can be readily tailored for the particular service conditions of the component. The method generally entails providing a pair of inner and outer mold members that form a cavity therebetween. One or more powders and any desired reinforcement material are then placed in the cavity and then consolidated at an elevated temperature and pressure in a non-oxidizing atmosphere. Thereafter, at least the outer mold member is removed to expose the consolidated powder structure. By appropriately shaping the mold members to tailor the shape of the cavity, the consolidated powder structure has the desired shape for the exterior shell of a component, such that subsequent processing of the component does not require substantially altering the configuration of the exterior shell. The airfoil can be produced as a free-standing article or produced directly on a mandrel that subsequently forms the interior structure of the component. In one embodiment, an airfoil is configured to have double walls through which cooling air flows.

Abstract: A wobble plate in a wobble plate compressor has a bevel gear positioned at a central portion thereof. The bevel gear is provided with a centered ball seat. A second bevel gear is supported on the cylinder block and also has a centered ball seat. A bearing ball is seated in both of the ball seats so that the wobble plate nutates about the ball. At least one of the bevel gears is coated with electroless composite plating layer having a self-lubricative material, such as polytetrafluoroethylene (PTFE), dispersed therein. Consequently, the bevel gears have low frictional resistance, high hardness and improved anti-seizure characteristics.

A mold is provided to cast a light metal into a predetermined shape. A nickel coated carbon phase structure is placed into a portion of the mold. The light metal is cast into the mold around the carbon structure to wet an interface between the light metal and the nickel coated carbon structure. A nickel-containing intermetallic phase is formed in the light metal proximate the nickel coated carbon to provide increased wear resistance. The light metal is then solidified to form the metal matrix composite.
