Resumo
Neste trabalho foram estudados os efeitos de inibição da corrosão de fendas de superliga de níquel em soluções clorídricas 22 a partir do emprego de espécies químicas de carbonato. Técnicas como Curvas de Polarização Anódicas e Potenciodinâmicas-Galvanostáticas-Potenciodinâmicas (PD-GS-PD) espectroscopia de impedância eletroquímica e Microscopia Eletrônica de Varredura (MEV) foram usadas para determinar o comportamento passivo da liga em presença das espécies de carbonato. Os resultados indicaram que o ácido carbônico e o bicarbonato não apresentaram efeitos inibitórios nas condições estudadas. O carbonato apresentou razão molar crítica igual a R =[CO=3]/[Cl-] = 1 independente da concentração de cloreto. A presença de um pico anódico foi relacionada à concentração de carbonato. As velocidades de corrosão obtidas foram inferiores a 0,4μm/ano a 24h de imersão.
