On the relationship between parameters of melt spreading over the surface of substrates of variable composition and state diagrams

Abstract

Abstract On of metered-dose drops of various concentrations on a substrate of variable composition. The basis for the substrates and droplets is the contact melting (CM) method related to state diagrams which are used to study the concentration dependence of surface characteristics (spot shape and size, wetting and spreading, surface tension, etc.) under the same conditions which improves accuracy of the characteristics. It was found that the microstructure of the transition zone of the substrate-drop depends on the location of the drop on the substrate, i.e. on the concentration of the substrate.
