Abstract

PROCEDIMIENTO ELECTROLITICO DE COLORACION DEL ALUMINIO ANODIZADO, MEDIANTE LA MODIFICACION Y CONTROL DEL COLOR DE TRANSMISION DE LA PELICULA ANODICA. ESTE PROCESO PERMITE REPETIR DE UNA FORMA INDUSTRIAL Y CONTROLABLE LA COLORACION ELECTROLITICA DEL ALUMINIO ANODIZADO, CONTROLANDO DE UN MODO DIFERENCIADO E INDEPENDIENTE LAS COORDENADAS COLORIMETRICAS DEL COLOR, ES DECIR LA SATURACION, LA TONALIDAD Y LA LUMINOSIDAD. EL CONTROL DE LA SATURACION SE LOGRA EFECTUANDO UN ANODIZADO DEL ALUMINIO SOBRE EL ANODIZADO PREVIO, CON LO QUE SE LOGRA UNA MASA-GEL DE ALUMINA CON GRAN MOVILIDAD. A ESTA MASA-GEL SE LA SOMETE A UNA CORRIENTE QUE PROVOCA LA REALIZACION DE UNOS MICROPOROS EN CUYA BASE SE FORMA UNA MASA GEL CON FORMA ESFERICA QUE ACTUA A MODO DE MICROLENTES. EL CONTROL DEL COLOR FINAL SE LOGRA MEDIANTE LA APLICACION DE UNA CORRIENTE CONTINUA PULSANTE, SIENDO EL TIEMPO DE APLICACION EL QUE MARCARA EL COLOR DEL ESPECTRO VISIBLE OBTENIDO. EL CONTROL DE LA LUMINOSIDAD SE LOGRA MEDIANTE LA ELECTRODEPOSICION DE PARTICULAS METALICAS. FIGURA 7.
