Investigation of adhesion of chalcogenide glasses to silica glass

Abstract Adhesion of As 40 S 60 , Ge 10 As 22 Se 68 , As 30 Se 50 Te 20 , As 40 S 30 Se 30 , As 38 Sb 2 Se 30 Te 30 , As 30 Se 70 , As 35 Se 65 , As 37.5 Se 62.5 and As 40 Se 60 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 T g . 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.
