Abstract
A manifold for use in a process for coating different sized passages in a workpiece is provided. The manifold has an internal chamber, an inlet for receiving a flow of a coating gas, and a flow diverter within the internal chamber for separating the flow of coating gas into a first flow sufficient to coat a full length of surfaces of a first internal passage set having a first cross section dimension and a second flow sufficient to coat a full length of surfaces of a second internal passage set having a second cross section dimension smaller than the first cross section dimension.
Claims27
A manifold for use in a process for coating different sized passages in a workpiece comprising:
- an internal chamber;
- an inlet for receiving a flow of a coating gas;
- and
- means within the internal chamber for separating the flow of coating gas into a first flow sufficient to coat a full length of surfaces of a first internal passage set having a first cross section dimension and a second flow sufficient to coat a full length of surfaces of a second internal passage set having a second cross section dimension smaller than said first cross section dimension.
A system for coating internal passages of a workpiece comprising:
- a source of a coating gas;
- a manifold connected to said source of said coating gas and to said workpiece;
- and
- said manifold having an internal chamber, an inlet for receiving a flow of said coating gas, and means within the internal chamber for separating the flow of coating gas into a first flow sufficient to coat a full length of surfaces of a first internal passage set having a first cross section dimension and a second flow sufficient to coat a full length of surfaces of a second internal passage set having a second cross section dimension smaller than said first cross section dimension.
A process for coating internal passages of a turbine engine component, said process comprising the steps of:
- providing a source of a coating gas;
- providing a manifold connected to said source of said coating gas and to said workpiece;
- and
- separating the flow of coating gas within said manifold into a first flow sufficient to coat a full length of surfaces of a first internal passage set having a first cross section dimension and a second flow sufficient to coat a full length of surfaces of a second internal passage set having a second cross section dimension smaller than said first cross section dimension.
A system for coating internal passages of a workpiece comprising:
- at least one source of a coating gas;
- first manifold means connected to said at least one source of coating gas for delivering a first flow of coating gas to a first set of said internal passages;
- and
- second manifold means connected to said at least one source of coating gas for delivering a second flow of coating gas to a second set of said internal passages.
