Abstract
EL MATERIAL A TRATAR (W) SE PRECALIENTA HASTA UNA TEMPERATURA DE CARBURIZACION DE ENTRE 750 (GRADOS) - 950 (GRADOS) C Y SE TRATA MEDIANTE CALOR EN UNA ATMOSFERA DE CARBURIZACION DIRECTAMENTE SUMINISTRADA CON GASES DE HIDROCARBUROS Y OXIDANTES, EN LA CUAL SE CALIENTA HASTA 1000 (GRADOS) -1100 (GRADOS) C. ENTONCES, EL MATERIAL QUE ESTA SIENDO TRATADO (W) SE REFRIGERA DE FORMA FORZADA HASTA UNA TEMPERATURA POR DEBAJO DE LOS 600 (GRADOS) C, EL MATERIAL (W) SE RECALIENTA HASTA 750 (GRADOS) -850 (GRADOS) C Y LUEGO SE ENDURECE MEDIANTE SU TEMPLADO EN ACEITE (20), PREFERIBLEMENTE USANDO UNA TECNICA DE TEMPLADO DE FLUJO LAMINAR.
