 Abstract
An analytic solution of the freeze coating of a cylindrical object with a binary alloy is obtained by modeling the object as a line heat sink. In the freeze coating with a binary alloy, there exist s an extended region where phase change occurs instead of a sharp phase interface in the freeze coating of a pure substance. In this region, which is called mushy region, the solid and the liquid phases coexist in a geometrically complicated manner. Therefore a mushy model, which can properly treat the mushy region, is adopted in the present analysis. And the effect of convection in the liquid region is also considered. The system of governing equations and boundary conditions, derived from conservation law, is analyzed through similarity transformation and numerical integration. The effect of various processing parameters on the growth rate of the freeze coating is presented.
