Abstract
EL PROCESO CONSISTE EN SOMETER LAS PIEZAS A UNA NITRURACION, POR EJEMPLO EN BAÑO DE CIANATOS/CARBONATOS, Y A CONTINUACION A UNA OXIDACION, POR EJEMPLO UN BAÑO QUE CONTIENE NITRATOS ALCALINOS, HIDROXIDOS ALCALINOS, CARBONATOS ALCALINOS Y UNA PEQUEÑA CANTIDAD DE SALES ALCALINAS OXIGENADAS CUYO POTENCIAL NORMAL DE OXICLORREDUCCION ES INFERIOR A ELECTRODO DE HIDROGENO, PARA OBTENER UNA CAPA NITRURADA QUE COMPRENDE UNA SUB-CAPA PROFUNDA COMPACTA DE ESPESOR SUPERIOR A 4 MUM, Y UNA SUBCAPA SUPERFICIAL POROSA DE ESPESOR COMPRENDIDO ENTRE 2 Y 20 MUM, NO SIENDO EL DIAMETRO DE LOS POROS INFERIOR A 100 NM, Y A CONTINUACION EN DEPOSITAR UN ENLUCIDO DE FLUOROETILENO-PROPILENO (FEP) DE ESPESOR COMPRENDIDO ENTRE 3 Y 20 MUM, Y PREFERENTEMENTE INFERIOR A 15 MUM. LAS PROPIEDADES DE FRICCION DE LAS PIEZAS ASI TRATADAS SON AL MENOS TAN BUENAS COMO LAS DE PIEZAS QUE HAN SOPORTADO LAS OPERACIONES DE NITRURACION Y DE OXIDACION, MIENTRAS QUE LA RESISTENCIA A LA CORROSION AUMENTA NOTABLEMENTE, PASANDO DE 200-250 HORAS DE EXPOSICION A LA NIEBLA SALINA NORMALIZADA ANTES DE LA APARICION DE CORROSION A AL MENOS 500 HORAS, Y CORRIENTEMENTE A 1000 HORAS Y MAS. SE OBTIENEN RESULTADOS COMPARABLES A ENLUCIDOS DE PTFE, DE POLIMEROS Y COPOLIMEROS DE POLIURETANOS FLUORADOS O SILICONADOS Y DE POLIAMIDAS-POLIMIDAS.
