A flow element for fluidic contact with a hot gas flow inside an aircraft engine includes: a base material, which has a hot gas surface that faces the gas flow and a remote surface that is remote from the gas flow, the base material being completely surrounded by a chroming layer on the hot gas surface and on the remote surface; an adhesive layer on the chroming layer in first portions; an alitising layer, the alitising layer being arranged on the adhesive layer in the first portions; and a thermal barrier layer being arranged on the alitising layer in the first portions. The alitising layer is arranged on the chroming layer in second portions that do not have an adhesive layer, the chroming layer and the alitising layer forming a chroming-alitising layer in the second portions.

A combustor assembly includes a combustion liner defining a first radial opening, an outer sleeve that at least partially surrounds the combustion liner. The outer sleeve defines a second radial opening. A mounting body having a jacket portion and a flange portion surrounds the first radial opening and extends radially outwardly from an outer surface of the combustion liner towards the outer sleeve. The flange portion is at least partially disposed within the second radial opening. An auxiliary component extends radially within the jacket portion and includes a flange portion. The flange portion of the auxiliary component is connected to the flange portion of the mounting body via a first fastener, and the flange portion of the auxiliary component is connected to the outer sleeve via a second fastener.

A furnace includes a perforated flame holder formed from an array of tiles. The perforated flame holder is stabilized by a support member extending between at least adjacent tiles. Elongated support members may be positioned to extend through each of the tiles in a respective column of the array of tiles.

A method of coating a component includes attaching the component to a support that is configured to hold a plurality of components and placing a base of the support in a holder that is attached to rotatable member of a fixture, wherein an axis of the holder is parallel to an axis of rotation of the rotatable member. The method also includes transporting the fixture into a coating chamber wherein a direction of an exit stream of a coater in oriented perpendicularly to the axis of rotation, exposing the fixture and the component to a reverse transfer arc cleaning/pre-heating procedure, and exposing the fixture and the component to a coating procedure during which a coating is directed at the component in a direction perpendicular to the axis of rotation while the rotatable member is rotating. The method further includes transporting the fixture and removing the component from the support fixture.
