A method of fabricating complex, composite components for water-cooled, high temperature gas turbines is provided. The method utilizes hot isostatic pressure with molten glass as a pressure transmitting medium. Metal tubing and cladding are bonded to a component core under conditions such that the ends of the tubing extend above the molten glass whereby the pressure inside and outside of the tubing is maintained at equilibrium to prevent collapsing thereof during the application of hot isostatic pressure.

A method of making an article of manufacture comprising the steps of: (a) disposing a plurality of metal tubing sections at a preselected interface portion of said article in such a manner that at least one end of each tubing section extends external to said portion, (b) placing a preformed cladding

A method of making an article of manufacture comprising the steps of: (a) disposing a plurality of metal tubing sections at a preselected interface portion of said article in such a manner that at least one end of each tubing section extends external to said portion, (b) placing a preformed cladding over both said portion and the tubing whereby the said extending tube ends also project beyond the cladding and affixing the cladding to said portion to form an assembly, (c) masking exposed interfaces between the cladding and said portion, (d) subjecting the assembly to hot isostatic pressure in a pressure transmitting liquid at a sufficient temperature and pressure, while maintaining said tubing sections open to said pressure such that the same pressure exist inside and outside of said sections preventing said section from collapsing, and whereby the tubing and the cladding are metallurgically bonded to the article.
