Basing on hydrodynamics fundamentals we examine the behavior of properties and features peculiar to formation of contact sliding interaction space as isomorphic environment with a changing density caused by emission into surface destruction fractions space. The mathematical model describing dynamic behavior of theoretically isomorphic thin sliding contact layer is created for steady motion. Analysis of this model reveals the dependence of solid sliding space’s properties on driving dynamics, space orientation and properties of the multidimensional contact layer environment.
