Abstract

EL PROCESO CONSISTE EN SOMETER LA CAPA SUPERFICIAL DE UN METAL ELECTROLITICAMENTE OXIDABLE A LA ACCION DE UN CAMPO ELECTRICO CON UNA INTENSIDAD DE CAMPO MAS ELEVADA QUE LA INTENSIDAD DE DISRUPCION DURANTE UN PASO DE ANODIZACION. EN TALES CONDICIONES, LOS INTERCAMBIOS DE ENERGIA EXTREMADAMENTE INTENSOS OCURREN EN UNA REGION CONFINADA DE LA SUPERFICIE DEL ARTICULO SUMERGIDO; LOS RESULTANTES PROCESOS QUIMICOS Y FISICOS PRODUCEN, ENTRE OTRAS COSAS, ALGUNAS IMPUREZAS A ELIMINAR DE FORMA INMEDIATA Y UNA CAPA DE ACONDICIONAMIENTO DE LA SUPERFICIE UTIL PARA PROCESOS DE PRODUCCION POSTERIOR. EL PROCESO ES PARTICULARMENTE ADECUADO PARA EL TRATAMIENTO RAPIDO DE ABRAZADERAS DE ALEACION LIGERA Y OTROS MATERIALES OXIDABLES.THE PROCESS CONSISTS OF SUBMITTING THE SURFACE LAYER OF AN ELECTROLYTICALLY OXIDABLE METAL TO THE ACTION OF AN ELECTRIC FIELD WITH A FIELD INTENSITY HIGHER THAN THE DISTURBANCE INTENSITY DURING AN ANODIZATION STEP. UNDER SUCH CONDITIONS, EXTREMELY INTENSE ENERGY EXCHANGES OCCUR IN A CONFINED REGION OF THE SUBMERGED ARTICLE SURFACE; THE RESULTANT CHEMICAL AND PHYSICAL PROCESSES PRODUCE, AMONG OTHER THINGS, SOME IMPURITIES TO REMOVE IMMEDIATELY AND A LAYER OF CONDITIONING OF THE SURFACE USEFUL FOR SUBSEQUENT PRODUCTION PROCESSES. THE PROCESS IS PARTICULARLY SUITABLE FOR THE QUICK TREATMENT OF LIGHT ALLOY CLAMPS AND OTHER OXIDIZABLE MATERIALS.
