Abstract
processo de avaliação da resistência à corrosão a presente inveção se refere a um processo para avaliar a resistência à corrosão dos substratos dos metais revestidos, tais como as carrocerias, a uma taxa acelerada. um ânodo e cátodo revestido com o revestimento de proteção a ser testado são expostos a um eletrólito em uma câmara de um avaliador de resitência à corrosão. estes revestimentos são fornecidos com defeitos predeterminados e padronizados, tais como os micro-orifícios para acelerar a corrosão do substrato de metal subjacente de uma forma previsível e repetititva. o par do cátodo / ânodo revestido é submetido ao período inicial, seguido por uma série de voltagens dc predefinidas moduladas de forma triangular, triangular ou trapezoidal truncada para as durações predefinidas que são intercaladas com períodos de recuperação. os dados da impedância coletados são, em seguida, utilizados para alcançar a resistência do desempenho à corrosão do revestimento aplicado sobre o par do cátodo / ânodo. o avaliador precedente substancialmente reduz o tempo necessário para testar a corrosão a partir de diversos dias (40 dias ou um período superior) para alguns dias (cerca de dois dias).
