Abstract

SE DESCRIBE UN METODO DE PRODUCCION DE UN PRODUCTO RESISTENTE A LA CORROSION A PARTIR DE UN LINGOTE QUE COMPRENDE UN NUCLEO DE VIRUTAS FERROSAS FINAMENTE DIVIDIDAS COMPACTADAS EN BRIQUETAS EN UNA CUBIERTA DE ACERO INOXIDABLE Y EN LA QUE EL LINGOTE SE CALIENTA A UNA TEMPERATURA EN LA QUE LLEGA A SER LO SUFICIENTEMENTE PLASTICO PARA INSERTARLO EN UN PRODUCTO TERMINADO O SEMI TERMINADO MEDIANTE UNA OPERACION COMO RODAMIENTO. UN ADITIVO ES PREMEZCLADO CON LA VIRUTA EL CUAL, CUANDO SE CALIENTA EL LINGOTE, REACCIONA PARA FORMAR UNA ATMOSFERA EN EL INTERIOR DE LA CUBIERTA LA CUAL DESPLAZA O EVITA LA FORMACION DE DIOXIDO DE CARBONO Y/U OTROS GASES QUE A ELEVADAS TEMPERATURAS OXIDARIAN EL ACERO INOXIDABLE PARA FORMAR OXIDOS DE CROMO EN LA INTERFASE ENTRE LA CUBIERTA Y EL NUCLEO. EL ADITIVO ESTA PREFERIBLEMENTE EN FORMA DE POLVO. EJEMPLOS DE ADITIVOS ADECUADOS INCLUYEN UREA Y CLORURO DE AMONIO.
