Abstract
PROCEDIMIENTO PARA AUMENTAR LA RESISTENCIA A LA CORROSION DE PIEZAS DE HIERRO NITRURADAS. CONSISTE EN UN TRATAMIENTO DE OXIDACION DE LAS PIEZAS, A CONTINUACION DEL PROCESO DE NITRURACION. EL TRATAMIENTO DE OXIDACION SE EFECTUA EN UN BAÑO DE SALES OXIDANTES, A TEMPERATURAS ENTRE 250 Y 450GC, Y DURANTE UN TIEMPO COMPRENDIDO ENTRE 25 Y 45 MINUTOS; EL BAÑO DE SALES ESTA COMPUESTO POR DOS HIDROXIDOS DE METALES ALCALINOS Y UN NITRATO DE METAL ALCALINO EN PORCENTAJE ESTE ULTIMO, EN PESO, ENTRE EL 2 Y EL 20 POR 100 DEL TOTAL.
