METHOD FOR WELDING TIP OF SINGLE CRYSTAL TURBINE BLADE WITH OXIDATION-RESISTANT FILLER MATERIAL

PROBLEM TO BE SOLVED: To provide a method for accumulating a material in a turbine blade-shaped part (18) having a tip wall (34) extended by crossing a tip cap (36) and including first alloy having single crystal microtexture. SOLUTION: This method comprises steps for depositing second alloy having...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for accumulating a material in a turbine blade-shaped part (18) having a tip wall (34) extended by crossing a tip cap (36) and including first alloy having single crystal microtexture. SOLUTION: This method comprises steps for depositing second alloy having stronger high temperature oxidation resistance than that of the first alloy in at least part of the tip wall (34) and forming a restorative structure having substantially the same crystal orientation as that of the tip wall (34).
