STRENGTH OF CYLINDRICAL SPECIMENS SUBJECTED TO LASER HARDENING ALONG THE GENERATOR AND A SPIRAL PATH

摘要

We have shown that the path of a continuous CO_2-laser beam over the cylindrical surface of specimens in the course of their hardening substantially affects the strength of steels in cyclic axial tension and bending with torsion. Hardening on a spiral path ensures higher mechanical parameters as compared with that along the generator of the cylindrical surface.
