Abstract
TUBE DE RONTGEN A ANODE ROTATIVE QUI, A L'INTERIEUR D'UN BOITIER ETANCHE AU VIDE, PEUT TOURNER A L'AIDE D'AU MOINS UN PALIER LISSE DONT LES FACES PORTANTES COOPERANTES REALISEES EN TUNGSTENE, EN MOLYBDENE OU EN ALLIAGE DE CES DEUX METAUX, SONT HUMIDIFIEES MOLECULAIREMENT PAR UN ALLIAGE DE GALLIUM, A BAS POINT DE FUSION ET A FAIBLE TENSION DE VAPEUR, SERVANT DE LUBRIFIANT DE PALIER. L'HUMIDIFICATION EST TELLEMENT CONVENABLE QU'ETANT SOUMISES A CHARGE, LES FACES PORTANTES SONT SEPAREES ENTIEREMENT L'UNE DE L'AUTRE A L'INTERIEUR DU TUBE. A L'ARRET DE L'ANODE COMME EN ROTATION, L'ALLIAGE DE GALLIUM N'EST PAS REFOULE HORS DU PALIER, CE QUI EVITE QUE LES FACES PORTANTES SE SOUDENT L'UNE A L'AUTRE. L'USURE ET LE BRUIT GENANT DU PALIER SONT EXTREMEMENT FAIBLES. L'HUMIDIFICATION CONVENABLE EST OBTENUE EN RENDANT EXEMPTES D'OXYDES LES FACES PORTANTES ET L'ALLIAGE EN GALLIUM AVANT LEUR MISE EN CONTACT. APPLICATION A L'APPAREILLAGE RADIOSCOPIQUE UTILISE EN MEDECINE.
