Abstract

ALEACION DE CIRCONIO PARA EL ENVAINADO DE REACTORES NUCLEARES REFRIGERADOS POR AGUA. EL CUERPO (10) DE CIRCALOY SE SOMETE A UN TRATAMIENTO SUPERFICIAL MEDIANTE RAYOS LASER (40) PARA AUMENTAR LA RESISTENCIA A LA CORROSION, AL ENFRIAR RAPIDAMENTE EN FASE BETA DEL DIAGRAMA DE FASES DEL CIRCONIO Y ESTAÑO. EL HAZ DE RAYOS LASER, QUE SE MUEVE A UNA VELOCIDAD (V), FORMA UNA REGION (22) QUE SE CALIENTA A LA TEMPERATURA EN LA CUAL LOS GRANOS BETA DEL CIRCALOY NUCLEAN Y CRECEN. INMEDIATAMENTE DESPUES EL CIRCALOY SE ENFRIA, FORMANDO UNA PISTA (20) ENFRIADA EN FASE BETA. CONTROLANDO LA VELOCIDAD Y LA ENERGIA DEL HAZ SE PUEDE VARIAR EL ESPESOR DE LA PISTA (20).
