The mechanism and properties of laser hardening and surfacing of constructional steels and color aviation alloys are discussed. Laws of formation surfacing layer are investigated at restoration of the worn out steel surfaces. At optimum modes of laser processing essential increase of wear resistance and operational properties of color alloys and steels is revealed, both at them laser hardening and at restoration. It is established, that coupled surfaces of different details have the greatest wear resistance later laser hardening. Laser hardening and surfacing influence laser is investigated at mutual processing coupled surfaces in units of a sliding friction on an example of bearings of sliding in a combination "steel-bronze".
