Abstract

METODO MEJORADO PARA APLICAR RECUBRIMIENTOS, GENERALMENTE CONOCIDOS COMO ACABADOS SUPERFICIALES "METALIZADOS", SOBRE PARTES DE COMPONENTES ADAPTADOS PARA SU USO EN SUPERFICIES EXTERNAS DE MEDIOS DE TRANSPORTE, TALES COMO REJILLAS DE RADIADOR PARA AUTOMOVILES. UN PROCESO CONVENCIONAL REQUIERE, TRAS LA APLICACION DE CAPAS METALICAS INHIBIDORAS DE LA CORROSION, LA APLICACION DE NUEVO, UTILIZANDO UN PROCESO GALVANICO, DE UNA CAPA METALICA ADAPATADA PARA APORTAR LA COMBINACION DESEADA DE COLOR Y BRILLO, TAL COMO POR EJEMPLO EL LLAMADO ACABADO DE "TUBO DE CAÑON". LA PRESENTE INVENCION PROPONE LA ADICION DE UNA FASE DE GALVANIZADO SEGUIDA DE UNA FASE EN LA QUE LA PARTE SE MANTIENE A UNA TEMPERATURA NO SUPERIOR A 30 (GRADOS) C DURANTE AL MENOS 24 HORAS, Y ENTONCES POR UNA FASE MAS EN LA QUE LA MISMA CAPA DE GALVANIZADO SE RETIRA Y LA CAPA MAS EXTERNA DEL METAL INHIBIDOR DE CORROSION SE ACTIVA EN LA FORMA TRADICIONAL.IMPROVED METHOD FOR APPLYING COATINGS, GENERALLY KNOWN AS "METALLIZED" SURFACE FINISHES, ON PARTS OF COMPONENTS ADAPTED FOR USE IN EXTERNAL SURFACES OF TRANSPORTATION MEDIA, SUCH AS RADIATOR GRIDS FOR CARS. A CONVENTIONAL PROCESS REQUIRES, AFTER THE APPLICATION OF CORROSION INHIBITING METAL LAYERS, THE APPLICATION AGAIN, USING A GALVANIC PROCESS, OF A METALLIC LAYER ADAPTED TO CONTRIBUTE THE DESIRED COMBINATION OF COLOR AND BRIGHTNESS, AS WELL AS CALLED CANNON TUBE ". THE PRESENT INVENTION PROPOSES THE ADDITION OF A GALVANIZED PHASE FOLLOWING A PHASE IN WHICH THE PART IS MAINTAINED AT A TEMPERATURE NOT HIGHER THAN 30 (GRADES) C DURING AT LEAST 24 HOURS, AND THEN FOR A MORE PHASE IN WHICH THE SAME LAYER OF GALVANIZED IS REMOVED AND THE MOST EXTERNAL LAYER OF THE CORROSION INHIBITING METAL IS ACTIVATED IN THE TRADITIONAL FORM.
