Abstract

Patente de Invenção: <B>"REVESTIMENTO DE UMA SUPERFìCIE SELETIVA DISCRETA DE UM ARTIGO"<D>. Um método para a restauração ou aperfeiçoamento de um revestimento resistente ao ambiente 22 de uma espessura total de revestimento dentro de uma faixa de espessura de desenho de revestimento sobre um substrato de metal 20 de um artigo 10, a aplicação de um metal de restauração ou aperfeiçoamento 30 em pelo menos uma área de superfície local discreta 28, 29. Em seguida, pelo menos a área de superfície local discreta 28, 29 é revestida com um revestimento resistente ao ambiente 32. Para o uso do método no sentido de restaurar um revestimento 22 sobre um artigo 10 que experimentou operação de serviço e a área de superfície discreta 28, 29 inclui uma quantidade indesejável de produtos de oxidação/corrosão, os produtos de oxidação/corrosão primeiro são removidos de uma porção externa 24 do revestimento 22 ao mesmo tempo que mantêm um revestimento 22 presente nas áreas de superfície discretas 28, 29 e mantendo todo o revestimento 22 das áreas de superfície adjacentes às áreas de superfície discretas 28, 29. Em seguida, o metal de restauração 30 é aplicado. Para o uso do método no sentido de aperfeiçoar um revestimento existente 22, pelo menos uma área de superfície discreta 28, 29 é selecionada com base em um padrão de ataque de oxidação/corrosão 16, 18 identificado a partir de artigos similares 10 que experimentaram operação de serviço em um aparelho de um desenho para o qual o artigo 10 é pretendido. Em seguida, o metal de aperfeiçoamento 30 é aplicado na área selecionada 28, 29.
