Zusammenfassung:	A crack repair method for a turbine component using spark plasma sintering: Applying filler material on a cracked portion of the turbine component. Applying joining pressure on the cracked portion of the turbine component by punches pressing on the component. Simultaneously heating the filler material by an application of electric current. Then cooling the heated filler material to form a joint at the cracked portion.
