Abstract

método para o tratamento de um substrato de superliga. trata-se de um método descrito para o tratamento de um substrato de superliga (32) que inclui pelo menos uma cavidade (33) contendo material óxido de metal aderente sobre sua superficie (31). um feixe de laser de alta taxa de repetição de pulso curto (46) é direcionado contra a superficie da cavidade por um periodo de tempo suficiente para remover substancialmente todo o material óxido de metal aderente. o feixe de laser (46) é caracterizado por uma densidade de potência de pico situada na faixa de cerca de 10 megawatts/cm2 a cerca de 10 gigawatts/cm2. em outra modalidade, um feixe de laser de alta taxa de repetição de pulso curto de alta potência é direcionado para uma região (62) sobre o substrato (64) que inclui a cavidade (60), sob as condições operacionais de laser que são capazes de cortar o material de superliga; de modo que uma região de contorno (66) seja formada dentro do substrato e que inclua a cavidade. a cavidade pode ser uma fenda em uma pá de turbina e a fenda (60) pode ser reparada após o tratamento através de soldagem ou outra técnica adequada.
