Investigation of adhesion of chalcogenide glasses to silica glass

Adhesion of As40S60, Ge10As22Se68, As30Se50Te20, As40S30Se30, As38Sb2Se30Te30, As30Se70, As35Se65, As37.5Se62.5 and As40Se60 glasses to silica glass is studied by the steady detachment method in the temperature range of 80-210 °C. The separation tension of the studied chalcogenide glasses from silica-glass substrate increases with temperature exponentially and has the maximum with the value of 2000-2600 kPa at temperatures close to Tg. The value of adhesion is shown to depend on the temperature, the surface roughness of silica glass, the chalcogenide glass composition, and the time of formation of adhesive contact.
