摘要： Systems and methods are provided herein useful to analyzing weld quality. In some embodiments, the systems and methods identify or predict weld characteristics such as surface discontinuities and/or subsurface discontinuities based on surface topology data and/or welding process parameters. The systems and methods described herein leverage machine learning algorithms to identify relationships between historic weld characteristics and historic pre-weld surface topology, historic post-weld surface topology, and/or historic welding process parameters. Thus, the systems and methods described herein may identify weld characteristics for a weld based on the relationships and the pre-weld surface topology, post-weld surface topology, and/or welding process parameters for the weld. Further, the systems and methods described herein may also identify weld as conforming or not conforming to one or more weld standards based on the relationships and the pre-weld surface topology, post-weld surface topology, and/or welding process parameters for the weld.

摘要： A method of forming an erosion shield for a turbine blade includes depositing a layer of filler material defining an upper surface. The method also includes depositing a layer of erosion-resistant material across the upper surface of the layer of filler material. An interface is defined between the layer of filler material and the layer of erosion-resistant material and has a shape of the upper surface. The method also includes machining the layer of filler material to produce the erosion shield. The erosion shield has the layer of erosion-resistant material, the machined layer of filler material, and the interface defined therebetween. An inner surface of the erosion shield is defined by the machined layer of filler material that is sized and shaped for attaching to a leading edge of the turbine blade. Each of the interface and the inner surface extend a length of the erosion shield.

摘要： A protected component is provided, which includes: a substrate defining a surface; and a regenerative surface treatment on the surface of the substrate. The substrate comprises an aluminum-based alloy. The regenerative surface treatment comprises an array of environmentally reactive deposits dispersed on the surface of the substrate, with each environmentally reactive deposit of the array defining a discrete region on the surface. The array of environmentally reactive deposits comprise at least one reactive element comprising Al, Zn, V, Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sc, Sm, Tb, Tm, Y, Yb, Mo, Si, Ca, W, a mixture thereof, or alloys thereof.
