Title

Abstract
(EN)
The unique character of the method of remelting of a surface in the presence of a steam channel is related to the fact that during the remelting process a processed element is subject to vibrations. The vibrations parameters are uniform at any given point of the remelted element. The element surface remelting method is unique since the process is performed at a temperature below the ebullition temperature and during the remelting process the element being processed is subject to vibrations. The surface is remelted using a laser or electron beam.
(FR)
Le caractère unique du procédé de refusion d'une surface en présence d'un canal de vapeur d'eau est correlé au fait que, pendant le procédé de refusion, un élément traité est soumis à des vibrations. Les paramètres des vibrations sont uniformes à n'importe que point donné de l'élément refondu. Le procédé de refusion de la surface de l'élément est unique étant donné que le procédé est effectué à une température au-dessous de la température d'ébullition et pendant le procédé de refusion, l'élément qui est traité est soumis à des vibrations. La surface est refondue à l'aide d'un faisceau laser ou électronique.
