Abstract

UN DIENTE ARTIFICIAL SINTERIZADO QUE TIENE UNA ELEVADA DENSIDAD, SE OBTIENE A PARTIR DE MEZCLAS DE POLVO DE METAL NOBLE CON UNA DISTRIBUCION DE PARTICULAS BI O POLIMETAL Y SE REALIZA POR OPERACIONES DE SECADO Y DE SINTERIZADO. SE TRATA TERMICAMENTE ENTRE 100 Y 400 C Y DURANTE 5 A 45 MINUTOS LOS DIENTES ARTIFICIALES SECADOS QUE SE HAN PRODUCIDO EN UNA BARBOTINA SE CALIENTA A 800 C CON UNA VELOCIDAD DE CALENTAMIENTO ENTRE 50 A 300 K/MIN LOS DIENTES ARTIFICIALES SCADOS Y SE SINTETIZA ESTOS DIENTES CALENTADOS CON UNA VELOCIDAD DE CALENTAMIENTO ENTRE 20 Y 200 K/MIN. EL DIENTE PERMANECE ENTRE LAS TEMPERATURAS DE SOLIDOS TSOLIDOS-200 Y TSOLIDOS-70. LOS TSOLIDOS ES LA TEMPERATURA DE SOLIDOS DE LA ALEACION SINTERIZADA. EL ENFRIAMIENTO PUEDE EFECTUARSE A VACIO O CON ATMOSFERA PROTECTORA DE GAS.
