Efeito do recobrimento eletroquímico de níquel (Banho de Watts) na microestrutura de aços inoxidáveis super duplex soldados pelo processo de laser pulsado Nd:YAG
Palavras-chave:
Corrosivo. Cisalhamento. Permeabilidade magnética. Análise comparativa. AISI 201. AISI 304.Resumo
Os aços inoxidáveis super duplex possuem uma microestrutura bifásica, com austenita e ferrita em proporções semelhantes, garantindo alta resistência mecânica e à corrosão. Contudo, após soldagem, a microestrutura tende a ser desbalanceada, com predominância de ferrita, comprometendo suas propriedades. Este estudo investigou o uso do Banho de Watts para corrigir o balanço de fases em um aço inoxidável super duplex UNS S32750 soldado por laser pulsado Nd:YAG. Três condições foram analisadas, variando o tempo do banho. A pesquisa avaliou a morfologia das fases, frações volumétricas e composição por EDS, demonstrando que o Banho de Watts, ao formar uma camada de níquel, foi eficaz na correção do desequilíbrio de fases na soldagem.
