Publication number: 20130075263Abstract: A method of repairing damaged airfoils. The method comprises the steps of stripping thermal barrier coatings from the airfoil. After the coatings are removed, cracks are removed from the airfoil. Cracks that appear in the bond coat area over the airfoil fillet portion are removed by locally grit blasting the fillet portion of the airfoil. This operation also results in locally removing the bond coating from the fillet portion. Cracks and other damage sustained by the airfoil tip are removed and replaced by welding superalloy material. The airfoil then may be cleaned by thermal etching. The airfoil is then placed in a plating tool permitting preferential plating of airfoil areas from which plating has been removed. After plating, the airfoil is then heat treated to diffuse the platinum coating with the superalloy substrate materials. The diffusion heat treated airfoil is aluminided by any aluminiding process, forming a PtAl coating.Type: ApplicationFiled: September 23, 2011Publication date: March 28, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: Nicholas Shawn WOODARD, Michael H.

Publication number: 20130061920Abstract: A photovoltaic cell (100) is proposed. The photovoltaic cell includes a substrate (105; 105?) of semiconductor material, and a plurality of contact terminals (Tf,Tb) each one arranged on a corresponding contact area (122) of the substrate for collecting electric charges being generated in the substrate by the light. For at least one of the contact areas, the substrate includes at least one porous semiconductor region (125) extending from the contact area into the substrate for anchoring the whole corresponding contact terminal on the substrate. In the solution according to an embodiment of the invention, each porous semiconductor region has a porosity decreasing moving away from the contact area inwards the substrate. An etching module (400) and an electrolytic module (700;700?;800;800?) for processing photovoltaic cells, a production line (900) for producing photovoltaic cells, and a process for producing photovoltaic cells are also proposed.Type: ApplicationFiled: March 12, 2011Publication date: March 14, 2013Applicant: RISE TECHNOLOGY S.R.L.Inventor: Marco Balucani

Publication number: 20130061875Abstract: A plating apparatus includes a vessel for holding a bath of plating liquid. A head is adapted to hold a work piece, such as a silicon wafer, in the vessel, with a seal on the head sealing against the work piece. A component cleaner assembly may be used to automatically clean a component of the plating apparatus, such as a seal or a contact ring. The cleaner assembly has a component contactor, such as a brush, on an arm. An arm actuator is linked to the arm for moving the arm from a retracted position, to a deployed position, where the contactor is in physical contact with the component. A method for cleaning a component of a plating apparatus includes moving a scrubber or contactor into contact with the component and applying a cleaning liquid onto the component adjacent to the contactor.Type: ApplicationFiled: September 14, 2011Publication date: March 14, 2013Inventor: Daniel J.
