Abstract

a. Procédé de préparation de corps par frittage d'une poudre. b. Après avoir découpé et soudé le tube 6 d'évacuation, on réunit d'une manière étanche au gaz un tube 13 à la bague 10 par une soudure 14, puis on emplit d'une poudre 15 l'espace compris entre le tube 6 d'évacuation et la bague 10 et le tube 13. Ensuite, on rend étanche le tube 13 par un couvercle 16, qui est fixé au tube 13 par une soudure 17. c. Métallurgie des poudres.
