Abstract: A turbine engine component may comprise a Ceramic Matrix Composite (CMC) structure including a plurality of nominally dense plies, wherein each of the plurality of the nominally dense plies are bonded by at least one of a Field Assisted Sintering Technique (FAST), a Spark Plasma Sintering (SPS), or a localized heating at a bonding interface. The turbine engine component may include an airfoil extending between a first platform and a second platform, wherein the airfoil, the first platform, and the second platform define the CMC structure.

Abstract: A cost-effective method of forming a hydrophobic coating on a substrate and coated substrates are disclosed. Specifically, the method comprises applying amorphous powders of an alloy to the substrate through a cold spray process. Also provided is a novel type of hydrophobic coating made of metallic glasses or amorphous alloys. The hydrophobic coatings offer advantages such as, low cost, low maintenance, and high corrosion resistance.
