The determination of technological parameters of the combined laser-ultrasonic finishing-hardening processing using temperature-time mode thermo-deformation surface hardening.
The study is based on using combined of laser-ultrasonic finishing-hardening processing with using the laser beam and ultrasonic concentrator with a tip namely to evaluate the productivity of the effective hardening and finishing of the surface layer. The methods for calculating the temperature-time mode thermo-deformation cycle plastic deformation ultrasonic tip in combination with high cooling after heating laser beam using combined laser-ultrasonic finishing-hardening processing are suggested. Dependences for the definition of the surface temperature and the time required energy of the laser beam ultrasonic pin at a given depth of strengthening for receiving the optimal parameters, which will provide increased hardness (strength), micrometrical and wear resistant characteristics of the surface layer for steel products and refractory metals and their alloys are presented.
The combined method of laser-ultrasonic finishing-hardening processing can use for responsible details of different purpose are suggested.
