摘要： A method of creating an article from investment casting includes forming a ceramic seed well, heating the ceramic seed well to form a hardened ceramic seed well, attaching a meltable pattern to the hardened ceramic seed well, coating the hardened ceramic seed well and the meltable pattern with hardenable ceramic material, heating the hardenable ceramic material to melt the meltable pattern, removing the meltable pattern from the hardenable ceramic material, firing the hardenable ceramic material to form a ceramic mold having a cavity, placing a seed within the hardened ceramic seed well, and pouring molten metal into the hardened ceramic seed well and the cavity. The cavity of the ceramic mold is in communication with the hardened ceramic seed well.

摘要： A coated nickel base superalloy single crystal turbine airfoil blade (1), which is subject to gas turbine engine operation, can crack during refurbishment by a stress corrosion mechanism when exposed to certain corrosive media. The rapid thermal cycling that occurs during typical gas turbine engine operation results in high, non-uniform stresses across the airfoil, producing large localized residual strains in the article at ambient temperatures. Exposure to a corrosive environment, such as during coating removal or agressive cleaning, can produce chordwise cracks in a large number of the airfoils exposed. Such cracking is avoided by subjecting the articles to a preliminary stress relieving heat treatment which reduces the residual strains to a level below which cracking will not occur, prior to exposure to the corrosive media.

摘要： The invention is a process for removing ceramic thermal barrier layers from gas turbine engine hardware. A combination of chemical and mechanical steps are used to remove the thermal barrier coating from the substrate without removing the bond coat from the substrate. The process leaves the bond coat on the substrate in condition to receive a repair ceramic thermal barrier coating. The process includes a caustic solution treatment in an autoclave under controlled conditions followed by a mechanical abrasion process.

摘要： An electro-optical contact assembly provides a connection between an electrical system and a fiber optic system for transmission of a signal therethrough. The assembly includes a converter for converting the signal between electrical and optical forms. The assembly also includes a receptacle with a retention mechanism mounted thereon which allows secure retention of an optical fiber terminus in the receptacle. The retention mechanism allows manual release of its clip from engagement with the optical fiber terminus in order to allow removal of the terminus from the receptacle, thereby allowing optical connection and disconnection of the assembly from the electrical system as well as other systems by simply plugging and unplugging fiber optic termini into and out of the contact assembly. The assembly includes a conductor surrounding the receptacle and terminus to provide EMI and RFI shielding of the terminus. The assembly also includes a thermoelectric structure thermally connected to the converter for cooling of a laser in the converter.
