| Popis: | The paper analyzes results on the initial spreading kinetics in binary metal systems, including those that involve the formation of intermediate phases and mass transfer through the interface. The drop flowing technique is used to study the effect of temperature, drop mass, and mutual saturation of the melt and solid substrate in binary systems of copper and tin with iron, cobalt, and nickel and also of tin with Ni3Sn and Ni3Sn2 intermetallics on the spreading rate. The proposed formal kinetic analysis of the spreading process using exponential time dependences for the motion of the three-phase boundary and for the difference between cosines of quasiequilibrium and dynamic contact angles permits satisfactory description of spreading in nonsteady-state conditions for the initial stages of the process and determination of its modes. The nature of phase interaction corresponds to phase equilibria in the studied systems with tin. |
