The state of the preparation of the scientific equipment for realization of the "Material-Friction" space experiment is considered. We offer a method and give an estimate of the error of measurement of wear of pair friction under orbital flight conditions with the use of strain-gauge sensors. The design of a module and versions of layout of orbital tribometer are presented. We derived experimental results confirming a high wear resistance and decrease of wear of pair friction from materials with elements of self-organizing with increasing speed of slip under vacuum conditions.
