Abstract

EN LOS ELECTROLITOS ACIDOS QUE CONTIENEN SN (II) PARA EL COLOREADO DE CAPAS DE OXIDO ANODIZADO SOBRE ALUMINIO, O ALEACIONES DE ALUMINIO, O, PARA LA GALVANIZACION, SE OXIDA EL SN(II). LA ADICION DE SUSTANCIAS, LLAMADAS ESTABILIZADORAS, PUEDE IMPEDIR, EN MAYOR O MENOR GRADO, LA OXIDACION, ES DECIR, EL SN(II), PUEDE ESTABILIZARSE MAS O MENOS. ADEMAS LA EFICACIA DEL ESTABILIZADOR ES DECISIVA PARA LA CALIDAD DE LOS DEPOSITOS O DEL COLOREADO DE LA CAPA DE ELOXAL. ES CONOCIDO QUE, EN PRESENCIA DE CANTIDADES CONSIDERABLES DE SN(IV) JUNTO AL SN(II), EMPEORA LA CALIDAD DEL TRATAMIENTO SUPERFICIAL A CONSECUENCIA DE UNA ESTABILIZACION INSUFICIENTE DEL SN(II). UN ELECTROLITO ACIDO QUE CONTIENE SN(II) CON UNA ADICION DE, AL MENOS, UNA DIFENILAMINA SOLUBLE O UN DERIVADO DE LA MISMA, ESTABILIZA EL SN(II) Y DA LUGAR A COLORACIONES SIN DEFECTOS.
