Abstract
"MéTODO PARA APASSIVAçãO". A invenção refere-se a um método para a apassivação de zinco, cádmio ou as ligas dos mesmos, de modo específico de ligas de zinco e níquel, por meio de uma solução isenta de cromo (VI) que contem um agente de complexação fraco, de preferência ácidos di- ou tricarbónicos, de preferência um complexo do cromo (III) - oxalato e Co^ 2+^ caracterizado em que a concentração de Co^ 2+^, é maior do que 30 g/I.
