Abstract

EN UN PROCEDIMIENTO PARA FABRICACION DE BARRAS DE ALEACION DE WOLFRAMIO, ESPECIALMENTE DE ELECTRODOS DE WOLFRAMIO PARA SEGMENTOS DE SOLDADURA DE GAS PROTECTOR DE WOLFRAMIO, SONDADURAS DE PLASMA, FUNDICION DE PLASMA Y SIMILARES, EN QUE EL WOLFRAMIO EN FORMA DE POLVO SE PRESIONA CON ADICION DE OXIDO MEZCLADO, SE SINTERIZA, SE ELABORA MECANICAMENTE Y SE SOMETE A UN TRATAMIENTO DE RECRISTALIZACION, ESTA PREVISTO PARA CONSEGUIR UNA INTEGRACION DE LANTANO ELEVADA AUN NO REALIZADA, QUE EL WOLFRAMIO EN POLVO SE ALEA CON UNA ADICION DE OXIDO DE LANTANO DESTENSADO DE 1,8 A 2,2% DE PESO, CON RESPECTO AL PESO GENERAL, QUE EL PRENSADO SE EMPRENDE CON UN MONTAJE DE PRESION DE VARIAS FASES Y QUE LA SINTERIZACION SE LLEVA A CABO CON UNA DISPOSICION DE TEMPERATURA DE VARIAS FASES.
