Sticking Temperature Investigations Of Glass/Metal Contacts - Determination Of Influencing Parameters

Sticking experiments between hot viscous glass and metallic substrates have been performed with a glass presson a laboratory scale, allowing a precise determination of the sticking temperatures, Ts, vs selected experimental parameters (nature of the substrate, composition of the glass). Complementary surface analyses have also been carried out to identify the surface and interface reaction products following the glass/metal contact. Experimental results have been compared to ternary phase diagrams, in order to test the reliability of thermodynamic calculations to predict the nature of the phases produced by contact at high temperature.
