Abstract

"PROCESSO A BASE DE MICRONDAS PARA A FORMAçãO DE UM REVESTIMENTO". Um processo para a formação de um revestimento (28) sobre a superfície de um substrato (14, 24), no qual a fonte de calor para o processo de revestimento e uma radiação em microondas (18) de tal forma que o aquecimento do material de revestimento é seletivo e suficiente para fundir e unir o material de revestimento no substrato (14, 24) sem aquecer excessivamente o substrato (14,24). O processo compreende formar um material de revestimento (10) compreendendo partículas em pó (12) que são pequenas o suficiente de modo a serem altamente susceptíveis a radiação em microondas (18). O material de revestimento (10) é aplicado na superfície do substrato (14, 24) e submetido à radiação em microondas (18) de tal forma que as partículas em pó (12) dentro do material de revestimento (10) casem com a radiação em microondas (18) e fundam de forma suficiente de modo a formar um revestimento (28) na superfície do substrato (14,24). A radiação em microondas (18) é então interrompida de modo a permitir que o revestimento (28) resfrie, se solidifique e se ligue mecanicamente ao substrato (14,24).
