Abstract
A HVOF process is used for applying brazing materials to repair surfaces of a substrate such as a turbine blade. The brazing material is applied in powdered form and is free of binders and adhesives. The brazing materials may be any one or more of a nickel based, cobalt based or ferrous based high temperature brazing material. Alloys of these elements may be used together with a temperature depressing melting point element such as boron or silicon.
Claims6
A repair deposit on a substrate comprised of a brazing material characterized in being binder-free and carbon-free and having a porosity of less than 2%.
A substrate having at least one repair deposit thereon, said repair deposit characterized in being binder-free and carbon-free and having a porosity of less than 2%.
A turbine blade having at least one repair deposit thereon, said repair deposit characterized in being binder-free and carbon-free, in having a porosity of less than 2% and in being selected from the group consisting of at least one of nickel-based, cobalt-based and ferrous-based brazing material.
