An air seal for use in a gas turbine engine. The seal includes a thermally sprayed abradable seal layer. The abradable material is composed of aluminum powder forming a metal matrix, and co-deposited methyl methacrylate particles and/or hexagonal boron nitride particles embedded as filler in the metal matrix.

Abradable seal and method of producing a seal

A mask for masking a component at an annular boundary comprises a wall () having an inner first rim portion having a first inner diameter (D) and an outward rebate () adjacent the first rim portion.

Spray masking for rotors

A process for forming a ceramic coating on a substrate, such as a turbine engine component includes the steps of providing a substrate, creating a plasma which preheats the substrate, and forming a ceramic coating by injecting a powder feedstock into the plasma. The ceramic coating forming step comprises depositing ceramic particles having a mean size in the range of from 100 to 150 microns at constant particle morphology.

Process for forming an improved durability thick ceramic coating

A masking system protects portions of a part, such as a turbine engine component, to be coated. The masking system has a base, a conduit positioned on said base, a part to be coated being positioned over the conduit, and an annular plate positioned over the conduit and resting on a first portion of the part.
