Abstract

"MéTODO DE ALUMINIZAçãO EM FASE DE VAPOR SELETIVA DE UMA REGIãO". A presente invenção é um processo para a formação coberturas de alumineto de difusão em uma superfície não coberta (36, 38) de um substrato (42), sem a interdifusão de uma quantidade suficiente de alumínio na camada de cobertura (44) para afetar adversamente as propriedades mecânicas ou o potencial de crescimento da cobertura (44) de dita camada de cobertura (44). é provido um substrato metálico (42) compreendendo uma superfície externa (36, 38) e uma passagem interna (34) nesta definida por uma superfície interna (36), pelo menos uma parte da superfície externa (38) do substrato (42) sendo coberta por uma camada de cobertura (44) selecionada do grupo que consiste de uma base de <225>-NiAl, MCrAIX, um alumineto de difusão não encoberto, um alumineto de difusão encoberto, um alumineto de difusão em pacote, e um alumineto de difusão em pasta sobre dito substrato (42). A superfície externa (38) do substrato (42) é limpada. O substrato metálico (42) é submetido a um processo de depósito em fase de vapor de alumínio conduzido usando um ativador contendo flúor selecionado do grupo que consiste de AIF~ 3~, CrF~ 3~, NH~ 4~F e combinações destes, a uma taxa dentro da faixa de cerca de 1,02 moles de flúor por L/hr (0,036 moles por ft^ 3^ /hr) do gás de transporte a cerca de 5,10 moles de flúor por L/hr (0,18 moles por ft^ 3^ /hr) do gás de transporte, a uma temperatura dentro da faixa de cerca de 730<198>C (1350 <198>F) a cerca de 1050<198>C (1925<198>F), empregando um gás de transporte selecionado do grupo que consiste de argónio, nitrogênio, hidrogênio e combinações destes, o gás de transporte sendo provido a uma taxa dentro da faixa de cerca de 401 L/hr (20 ft^ 3^/hr) a cerca de 3398 L/hr (120 ft^ 3^/hr), por um período de tempo dentro da faixa de cerca de 2 horas a cerca de 10 horas. O substrato (42) é então resfriado. A presente invenção é também sobre um artigo em liga superalloy (20) coberto com uma camada de alumineto de difusão (40) usando o processo de cobertura com alumineto de difusão da presente invenção.
