Essay

In thesis a theory of friction of atomically smooth solid surfaces separated by boundary lubricant is constructed, whose melting and solidification are presented as the first- or second-order phase transitions. Stick-slip motion mode and memory effects associated with relaxation processes are described. Taking into account the effective viscosity dependence on the temperature and velocity gradient the static friction force is construed. The case when the contact area has domain structure with liquid- and solid-like sections is possible. When considering the elasticity of contact surfaces the front of melting extends from the boundary of the contact to the center of system.
