Abstract
LOS TRATAMIENTOS DE OXIDACION POR BOMBARDEO IONICO POSTDESCARGA CONDUCEN A LA FORMACION EN LA SUPERFICIE DE LOS METALES Y ALEACIONES PASIVAS DE UNA CAPA DE OXIDO DE ALGUNOS MICROMETROS DE ESPESOR QUE PROTEGE LOS SUSTRATOS DE LA CORROSION ULTERIOR. SE PONE EN CONTACTO EL GAS ACTIVADO POR LA DESCARGA ELECTRICA CON LA SUPERFICIE DE LA PIEZA (2) A OXIDAR LLEVADA A UNA TEMPERATURA COMPRENDIDA ENTRE 350 Y 650 C. EL INVENTO PUEDE SER UTILIZADO, EN PARTICULAR, PARA FORMAR UN REVESTIMIENTO PROTECTOR SOBRE UN ELEMENTO O ESQUELETO COMPLETO EN ALEACION DE ZIRCONIO PARA UN ENSAMBLAJE COMBUSTIBLE DE UN REACTOR NUCLEAR ENFRIADO POR AGUA.
