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.
