Abstract
Procedimiento para reparar álabes de turbinas desgastados, cuyos álabes son de una aleación metálica, que comprende las fases de rectificar hasta una dimensión predeterminada con precisión, un borde de la parte de escotadura en Z del refuerzo de montaje en un extremo del álabe, enmascarar el refuerzo en ambos lados del borde después de rectificado; someter el borde rectificado a una corriente de plasma que contiene una aleación metálica para recrecer el borde prácticamente a su dimensión original, y después sinterizar el álabe a temperaturas elevadas durante un periodo de tiempo predeterminado para templar la reparación.
