Kinetic wetting of a moving planar defect by a new phase

Close to a bulk phase transition, a moving planar defect can be covered by a layer of the ordered phase. This, in fact, happens above the transition point in some finite region of the temperature-velocity diagram. In the case of a first-order transition this region is furnished with a net of nonequilibrium phase-transition lines. The topology of this net resembles that of the phase diagram of a first-order wetting transition in thermal equilibrium. In particular, there appears a kinetic complete-wetting line where a significant change of the drag coefficient of the defect is predicted.
