Abstract

Método de fabricación de paletas de rotor que consiste en dar a una aleación blanda la forma de un cuerpo de paleta con sección curva , en unir una aleación dura al borde de ataque del cuerpo de la paleta, y revestir las superficies laterales posteriores de las porciones de la paleta, y revestir las superficies laterales posteriores de las porciones de borde de ataque y de borde de salida y también la totalidad de la superficie del lado frontal de la paleta, formando alternativamente por lo menos una capa de aleación de Ni-Cr-B-Si y de WC mediante pulverización, fundiendo a continuación las capas sobre dicha superficie .
