Abstract

UN TORNILLO DE ACERO INOXIDABLE AUSTEMITICO TIENE UNA SUPERFICIE FORMADA EN EL INTERIOR DE UNA CAPA DURA NITRURADA, Y LA PARTE DE LA CABEZA DEL TORNILLO QUE ESTA EN CONTACTO CON EL AIRE EXTERIOR TIENE SU CAPA SUPERFICIAL ULTRADURA DE LA CAPA DURA NITRURADA SEPARADA MEDIANTE RASCADO, PARA QUE SEA RESISTENTE AL OXIDO. INCLUSO CUANDO LA CAPA DE SUPERFICIE ULTRADURA SE SEPARA DE ESTA MANERA, UNA CAPA DURA INTERIOR DE LA CAPA DURA NITRURADA QUE ESTA PRESENTE DEBAJO DE LA CAPA SUPERFICIAL, PERMANECE PARA MANTENER LA DUREZA DE LA SUPERFICIE DEL TORNILLO. UN METODO PARA MANUFACTURAR EL TORNILLO DE ACERO INOXIDABLE AUSTENICO INCLUYE, DESPUES DE LA FORMACION DE LA CAPA DURA NITRURADA SOBRE LA SUPERFICIE DEL TORNILLO MEDIANTE NITRURACION, LA LIMPIEZA DE LA SUPERFICIE DEL TORNILLO DE ACERO INOXIDABLE CON UN GAS QUE CONTIENE FLUORO O FLUORURO ANTES DE LA NITRURACION. POR LO TANTO, CUALQUIER MATERIAL EXTRAÑA O CAPA OXIDADA SOBRE LA SUPERFICIE DEL TORNILLO SE SEPARA Y AL MISMO TIEMPO LA SUPERFICIE DEL TORNILLO SE ACTIVA DE TAL FORMA QUE LOS ATOMOS DE NITROGENO PENETRAN Y SE DIFUNDEN DURANTE LA NITRURACION PARA FORMAR UNA CAPA NITRURADA UNIFORME.
