Modelling the size of the diffusion zone when changing the conditions of manufacturing glass-metal composite made of borosilicate glass and steel

The aim of the work is to solve fundamental and practical problems of increasing the strength of glass and obtaining compound of dissimilar materials. Theoretically and experimentally, the effect of manufacturing technology on the properties of the joint zone of glass and steel is studied in the manufacture of the perspective composite material, which is glass and metal composite. The preliminary experimental studies of the specificity of the formation of the steel and glass compound with changing parameter values in the technology of obtaining glass and metal composite demonstrate that it is possible to form a zone lying entirely in the glass saturated with iron oxides. Different types of structures in the joint zone and its dimensions affect the strength characteristics of the composite. Knowledge of the nature of changes in the width of the joint between steel and glass when varying such parameters of the technological regime as temperature, maturity time and the use of solders will make it possible to regulate the structure and properties of the glass and metal composite. The article contains the experimental measurements of the width of the diffusion zone for various regimes and their statistical processing according to the scheme of the complete factor experiment. Basing on the complete factor analysis there has been modelled the size of the zone in the junction of CH-1 glass with steel 20 when varying different technological parameters including the method of pretreatment of the welded surfaces of steel and glass.
