The requirements to mechanical properties of machine parts are high today. That’s why the use of traditional techniques sometimes don’t allow us to receive the necessary quality parameters of the surface layer. In this connection modern manufacture uses the hybrid and combined technologies. The combined techniques can provide high accuracy, productivity, durability of parts due to the improvement parameters of the surface layer. Investigate the influence of the combined laser-ultrasonic processing on change relief and microhardness of metal products and determine the possibility of this method. The prospects of a combined laser-ultrasonic finishing and strengthening of surface finishing of parts, where the action is implemented on a metal surface of the laser-ultrasonic sources of energy that can not only improve the parameters of the surface layer of workpieces, but also to optimize the performance of modified surfaces to create competitive products. Use laser - ultrasonic action for finishing - strengthening processing will allow not only substantially improving the parameters of superficial layer of processing details but also optimization specifications of the modified surfaces to create competitive products. Propounded pilot test of the combined method of laser-ultrasonic finishing-strengthening processing suggest it can use to handle critical details of different purpose.References
