Molten film lubrication in armature-rail interface is an important mechanism in railgun design. In this article, the processes of thermal softening, melting and the subsequent melt lubrication occurring during the high speed sliding of a metal slider on another metal block are studied using analytical and finite element methods (FEM). Subsequently, an unsteady lubrication model is proposed to describe the behavior of molten film at the slider-rail interface.
