Abstract
The invention relates to a method for producing a component of a turbo-machine, especially the blade of a water turbine or a liquid pump, with a wear-endangered area, comprising the following steps: the component is produced in a conventional manner, e.g. by means of casting and NC machining in addition to grinding; a cast is taken of at least the wear-endangered component to obtain a negative model; the wear-endangered area is removed in a defined manner from the full component thus produced; the wear part is produced using a negative model and by casting with a casting compound whose material properties meet the practical requirements; the wear part and the main part are joined to each other.
