Abstract

EN UNA PROCEDIMIENTO PARA LA PREPARACION DE PIEZAS, AL MENOS PARCIALMENTE MECANIZADAS, CON SUPERFICIE DE ALUMINIO, Y SUS ALEACIONES, PARA UN POSTERIOR RECUBRIMIENTO, DICHAS PIEZAS SE TRATN PRIMERAMENTE POR RECOCIDO Y/O DECAPADO EN MEDIO ACIDO OXIDANTE Y A CONTINUACION SE REVISTEN CON UNA CAPA DE CONVERSION. RESULTA PARTICULARMENTE VENTAJOSO DECAPAR PRIMERAMENTE LAS PIEZAS EN UNA SOLUCION QUE CONTENGA HNO3 + HF Y/O HNO3 Y A CONTINUACION REVESTIRLAS CON UNA CAPA DE CONVERSION MEDIANTE CROMATIZACION AMARILLA O FOSFATACION DE CINC MANGANESO ACTIVADA POR FLUORORU Y, DESPUES DE ESTO, RECUBRIRLOS POR UN PROCEDIMIENTO DE INMERSION ELECTROLITICA, RECUBRIMIENTO POR PULVERIZACION O RECUBRIMIENTO "HIGH SOLID".IN A PROCEDURE FOR THE PREPARATION OF PARTS, AT LEAST PARTIALLY MECHANIZED, WITH ALUMINUM SURFACE, AND THEIR ALLOYS, FOR A LATER COATING, SUCH PARTS ARE FIRST TREATED BY COATING AND / OR PICKLING IN A RECOVERED OXIDIZING MEDIUM WITH A RECOIDING RECOVERY. OF CONVERSATION. IT IS PARTICULARLY ADVANTAGES TO FIRSTLY SEPARATE THE PARTS IN A SOLUTION CONTAINING HNO3 + HF AND / OR HNO3 AND, TOGETHER, COAT WITH A CONVERSION LAYER THROUGH A YELLOW CROSS-BREAKING, DEPOSIT, AND DESPOSE OF ANY MANUFACTURERS ELECTROLYTIC, SPRAY COATING OR "HIGH SOLID" COATING.
