Abstract
Patente de Invenção para "MéTODO DE TRATAMENTO DOS COMPONENTES METáLICOS" Um método de formação de um produto metálico. Os atributos de um produto de peça de trabalho final são selecionados (etapa um). Uma composição de substrato apropriada é determinada dependendo dos atributos selecionados (etapa dois), Um substrato da peça de trabalho é formado para se aproximar às dimensões finais (etapa três). Uma composição de material de revestimento apropriado é determinada dependendo dos atributos selecionados (etapa quatro). O substrato da peça de trabalho é preparado para um processo de revestimento de alta densidade (etapa cinco). O processo de revestimento de alta densidade, tal como um spray térmico HVOF, é realizado para revestir o substrato da peça de trabalho com o material de revestimento (etapa seis). O material de revestimento é acumulado até a uma espessura efetiva para obter as dimensões finais desejadas após a realização de um tratamento de pressionamento isostático quente. Os parâmetros do tratamento de pressionamento isostático quente apropriados são determinados (etapa sete). O tratamento de pressionamento isostático quente é realizado no substrato da peça de trabalho revestido para obter um produto metálico tendo as dimensões finais desejadas e a ligação de difusão entre o material de revestimento e o substrato da peça de trabalho (etapa oito).
