Abstract

La invención se refiere a una aleación de soldadura fuerte (1) basada en níquel, basada en cobalto, o basada en níquel-cobalto para la soldadura fuerte a alta temperatura, y también a los métodos para producir o reparar componentes (7) de estructura modular y para reparar componentes dañados (7) que consisten de superaleaciones de cristal simple o direccionalmente solidificadas utilizando la aleación de soldadura fuerte (1). La aleación de soldadura fuerte comprende un primer componente de polvo metálico (2) que tiene tamaños de grano en el intervalo nanométrico y un segundo componente de polvo metálico (3) que tiene tamaños grano en el intervalo micrométrico, y está caracterizado porque la superficie de las partículas del segundo componente en polvo (3) está recubierta en capa delgada con partículas del primer componente en polvo (2), y porque la aleación de soldadura fuerte (1) comprende además elementos estabilizadores del contorno de grano, como elementos de aleación. Además, pueden estar presentes depresores del punto de fusión en la aleación de soldadura fuerte (1) en una cantidad comercialmente común o con una proporción considerablemente incrementada. La temperatura de fusión de la aleación de soldadura fuerte (1) y la probabilidad de recristalización son ventajosamente reducidas.
