Method of applying a protective coating to a turbine component

摘要

The method involves forming solder (5) on base material (2) through nano-film. The nano-film is ignited locally so as to produce exothermic reaction, where fusion of solder with the base material takes place to form a protective layer. An additional protective layer made of ceramic material is formed on the solder. The nano-film is made of aluminum nickel composition. The solder is made of silver copper indium titanium (Ag 59Cu 27.25In 12.5Ti), titanium copper nickel (TiCu 15Ni 15) or titanium zirconium copper nickel (TiZr 37.5Cu 15Ni 10).
