[en] The paper shows the advantage of the joint utilisation of the techniques of secondary ion mass spectroscopy and of photoelectron spectroscopy for the analysis of superficial layers of glasses subjected to deterioration. During an attack in the water, it is found that aluminium is attached to the surface of a float glass in a manner which seems independent of the concentration. A surface stratification, which suggests a corrosion mechanism, is observed. A second example deals with the deterioration of a phosphate glass in the presence of water. The presence of a surface precipitate of calcium phosphate is found above a layer of hydrated glass. The ESCA method makes it possible to specify that the apatite precipitate contains silicon or sodium

On montre l'interet de l'utilisation conjointe des techniques de spectroscopie de masse des ions secondaires et de spectroscopie de photoelectrons pour l'analyse des couches sperficielles de verres soumis a une alteration. Lors d'une attaque de l'eau, il apparait que l'aluminium se fixe a la surface d'un verre flotte d'une facon qui semble independante de la concentration. On observe une stratification superficielle qui suggere un mecanisme de corrosion. Un second exemple traite de l'alteration d'un verre phosphate en presence d'eau. On constate la presence d'un precipite superficiel de phosphate de calcium au-dessus d'une couche de verre hydrate. La methode ESCA permet de preciser que le precipite d'apatite renferme du silicium et du sodiumJournal
