Abstract:
PROBLEM TO BE SOLVED: To obtain a correct array position of a cooling air hole array in re-machining covered cooling air holes when a part with cooling air holes is covered. SOLUTION: According to this method, at least two cooling air holes are coated with masking material in a coating process, and the array position of the cooling air hole array (10) is obtained based on two cooling air holes 13', 13" not coated.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved method for generating a motion path for a spray gun for coating a component.SOLUTION: The method for generating a coating path is based on: ability to analyze uncertain data of surface geometry; preparation of a draft robotic path based on CAD data; an offline simulation of a coating thickness associated with a practical robot motion; an analysis of simulated thickness distribution; and subsequent iterative adjustment of an initial path for achieving a desired thickness tolerance of whole components.
Abstract:
A method for additive manufacturing with multiple materials. First (48), second (50), and third (52) adjacent powder layers are delivered onto a working surface (54A) in respective first (73), second (74), and third (75) area shapes of adjacent final materials (30, 44, 45) in a given section plane of a component (20). The first powder may be a structural metal delivered in the sectional shape of an airfoil substrate (30). The second powder may be a bond coat material delivered in a sectional shape of a bond coat (45) on the substrate. The third powder may be a thermal barrier ceramic delivered in a section shape of the thermal barrier coating (44). A particular laser intensity (69A, 69B) is applied to each layer to melt or to sinter the layer. Integrated interfaces (57, 77, 80) may be formed between adjacent layers by gradient material overlap and/or interleaving projections.
Abstract:
Cooling holes in a turbine component, such as a blade, vane or combustor transition, are formed in and surrounded by a micro surface feature (MSF) that protects the adjoining thermal barrier coating (TBC) from delamination or crack propagation during the hole formation or during engine operation. The MSF effectively functions as a circumferential sleeve around the cooling hole margin so that relatively more friable TBC material that would otherwise define the cooling hole margin is not directly exposed to coolant fluid exhausting the hole, foreign object damage (FOD) or contact with cooling hole formation tooling when fabricating the hole through the TBC layer. The MSF is formed as a projection from the component substrate or during subsequent application of a metallic bond coat (BC) layer.
Abstract:
By introducing solid, but releasable pins (4', 4'',...) into a structural part, the position of drilling axes of holes can be precisely determined by comparative measurement before and after coating.
