Abstract

A method prepares a repair material for and repairs a damage point in the surface of cast parts. Spray particles having the same cast structure as the cast part are used as materials. The particles are applied to the damage point by cold gas spraying. The cold gas spraying is performed such that the spray particles are not melted and, advantageously, the cast structure is retained after the spray particles contact the repair point. The repair point can thus be advantageously furnished with the same properties as the rest of the component to be repaired. The repair material can be produced in that a cast part having the required cast structure is reduced to small pieces.
