Fretting-wear of constructional steel 1045 after laser modification of surface

One from major problems of contact interaction of surfaces is the loss of a integrity of constructions in joints at the fretting-processes. As a rule, the fretting-wear has the latent character that is rather dangerous to responsible joints of airplane and space technology. The use of laser treatment of a surface can guarantee fretting-resistance within of the certain durability and safety factor medium carbon steel in joints. The laser processing of materials is especially favourable because of the localization and it allows to treat extremely those places, which are subjected to fretting-corrosion. Besides, laser exposure of coatings allows essentially to change properties of a surface and to prepare it for perception of alternating signs tangential loads.
