A coated article () includes a substrate () and a coating () on the substrate. The coating includes at least a first layer (). The first layer has: a matrix (); and a filler () at 2.0% to 40% by volume in the first layer. The first layer is selected from alkaline earth or transition metal (M) tungstates (MWO4); alkaline earth molybdates (MMoO); rare earth (RE) phosphates (REPO); and combinations thereof.

Dislocator chemistries for turbine abradable or machinable coating systems

A method () for applying a coating to a substrate () includes spraying () an aluminum-based coating layer () on the substrate. The coating layer is then infiltrated () with an aqueous solution (). The solution comprises: a source of chromium; and potassium hexafluorozirconate.

Solution based corrosion inhibitors for aluminum alloy thermal spray coatings

A blade has an airfoil having a tip. The blade has a metallic substrate and a coating system atop the substrate at the tip. The coating system has: a first layer of at least 99.0% weight nickel; an abrasive layer having a matrix and an abrasive at least partially embedded in the matrix; and a second layer between the first layer and the matrix. The second layer is tougher or more ductile than at least one of the first layer and the matrix.

Abrasive tip coating

A method for coating a substrate includes spraying a combination of powders. The combination of powders includes: HfSiO; ZrSiO; and, optionally, at least one of HfOand ZrO. A molar ratio of said HfSiOand HfOcombined to said ZrSiOand ZrOcombined is from 2:1 to 4:1. A molar ratio of said HfSiOto said HfOis at least 1:3.

Hafnon and zircon environmental barrier coatings for silicon-based components

A diffusion barrier coating on a nickel-based alloy substrate comprising the diffusion barrier being coupled to the substrate between the substrate and a composite material opposite the substrate, wherein the diffusion barrier comprises a nickel phosphorus alloy material.

Diffusion barrier to prevent super alloy depletion into nickel-CBN blade tip coating

Disclosed is a rotating component for a turbine engine including a first rotating component having a first snap surface and a second rotating component having a second snap surface wherein the first snap surface is configured to interlock with the second snap surface, and further wherein at least one of the first snap surface and the second snap surface have a friction enhancing material.
