A multicycle technology for laser surface hardening and stabilization treatment of slender parts

The article considers a mechanism for combining surface temperatures of the closest laser pulse under a discrete laser treatment. It is shown that a minimal transfer of the working surface causes a uniform surface heating within the laser irradiation zone, in addition to slow cooling of the surface outside the laser heating area. This facilitates stabilization of the properties of the working surface and reduction of the residual voltage. A case of the rational mode for the laser treatment of slender parts, such as torque shafts, is also provided.
