Abstract

IL PROCEDIMENTO CONSISTE NEL SOTTOPORRE ALL'AZIONE DI UN CAMPO ELETTRICO SUPERIORE AL VALORE DI ROTTURA LO STRATO SUPERFICIALE DI UN METALLO OSSIDABILE ELETTROLITICAMENTE IN FASE DI ANODIZZAZIONE.IN TALE REGIME SI PRODUCONO SCAMBI ENERGETICI ESTREMAMENTE INTENSI IN UNA REGIONE CONFINATA SULLA SUPERFICIE DELL'OGGETTO IMMERSO; I PROCESSI FISICI E CHIMICI RISULTANTI PRODUCONO TRA L'ALTRO L'ESPULSIONE PRESSOCHE' IMMEDIATA DEI CONTAMINANTI NONCHE' UNO STRATO DI CONDIZIONAMENTO SUPERFICIALE UTILE PER SUCCESSIVE OPERAZIONI. IL PROCEDIMENTO E' PARTICOLARMENTE UTILE PER IL TRATTAMENTO AD ALTA VELOCITA' DI NASTRI IN LEGA LEGGERA O ALTRI MATERIALI OSSIDABILI.THE PROCEDURE IS TO SUBJECT THE SURFACE LAYER OF AN ELECTRICALLY OXIDABLE METAL IN THE ANODIZATION PHASE TO THE ACTION OF AN ELECTRIC FIELD EXCEEDING THE BREAKING VALUE. THE RESULTING PHYSICAL AND CHEMICAL PROCESSES PRODUCE ALMOST IMMEDIATE EXPULSION OF CONTAMINANTS, AS WELL AS A LAYER OF SURFACE CONDITIONING USEFUL FOR SUBSEQUENT OPERATIONS. THE PROCEDURE IS PARTICULARLY USEFUL FOR THE HIGH SPEED TREATMENT OF LIGHT ALLOY TAPES OR OTHER OXIDABLE MATERIALS.
