Abstract
Methods for coating a target surface of an article having one or more passageways include fluidly connecting a temperature controlled fluid to at least one passageway, passing the temperature controlled fluid through the at least one passageway, wherein the temperature controlled fluid at least partially controls a temperature profile of the article, and coating the target surface, wherein the temperature profile of the article at least partially controls a microstructure of the coating.
Claims20
A method of coating a target surface of an article comprising one or more passageways, the method comprising:
- fluidly connecting a temperature controlled fluid to at least one passageway;
- passing the temperature controlled fluid through the at least one passageway, wherein the temperature controlled fluid at least partially controls a temperature profile of the article;
- and,
- coating the target surface, wherein the temperature profile of the article at least partially controls a microstructure of the coating.
A temperature controlled coating system for coating a target surface of an article comprising one or more passageways, the temperature controlled coating system comprising:
- a temperature controlled fluid source that fluidly connects to at least one passageway of the article and passes a temperature controlled fluid through the passageway, wherein the temperature controlled fluid at least partially controls a temperature profile of the article;
- and,
- a part coater that coats the target surface with a coating, wherein the temperature profile of the article at least partially controls a microstructure of the coating.
