Abstract:

Youngs modulus, linear thermal expansion coefficient, stress, microhardness, wear resistance, adhesion and cohesion strength for thin films of As2S3, As2Se3, Ge28Sb12Se60, Ge33As12Se55 and Ge36As4S60 chalcogenide glasses thermally deposited onto unheated zinc selenide substrates have been determined. The interrelationship between mechanical parameters of the films has been studied. Wear resistance of chalcogenide films has been found to be related to the adhesive force and mechanical parameters used in the formal theory of glass strength. The effect of the additional stress arising in result of the temperature increase under friction on the wear resistance of the films has been shown.
