Lazerio spinduliuotės ir ultragarso kombinuotas poveikis plienui / The combined influence of laser radiation and ultrasound on steelValys, Saulius 12 June 2006 (has links)
Recently among different ways of processing of materials the combined processing is applied. Applying different complex methods of processing of a surface of materials, it is possible to reduce a roughness of a processable surface, to increase thickness of a layer of the processed surface, to increase stability to wear process and microhardness. The further prospects in processing metals are opened with use of laser radiation and ultrasonic fluctuations. It is possible to notice, that complex ways of processing of metals are still not so widely investigated. This work is intended for research of a structure of steel in the field of influence of the combined laser radiation and ultrasonic fluctuations. It is established, that applying ultrasonic fluctuations at technologies of laser processing metals, it is possible to reach more uniform distribution of impurity in a surface of metal, to level a relief of the processed surface.
