In this work, the influence of parameters gas tungsten arc welding on the surface properties of a 100Cr6 steel was studied. Four different the current intensity has been used to remelting surface of the steel. Results of the effect of the current intensity arc electric on the microhardness, friction coefficient and wear intensity 100Cr6 steel was presented. Wear mechanisms were investigated by optical and scanning electron microscopy. Tribological test showed that the remelting with current intensity to 60A surface of the 100Cr6 leads to reduction of wear intensity in comparison to the conventional heat treatment. If treatment was made with current arc intensity - 80 A and more the wear intensity increased. During tribology tests two kinds wear material were distinguished: abrasive wear and adhesive wear.

The algorithm of the parameter calculation of macro-geometry, kinematics, macro- and micro-contacting, wear rate as well as those of frictional resource of cylindrical gearings with external evolvent toothing are presented. The most widely used in aircraft engine external toothing cylindrical gearings with evolvent tooth profile and transition curve with undercut are regarded as subject of inquiry.
