Title
(EN) METHOD OF INCREASING HEAT EXCHANGE SURFACES AND ACTIVE SURFACES OF METAL ELEMENTS INCLUDING, IN PARTICULAR, HEAT EXCHANGE SURFACES
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 duting the remelting process the element being processed is subject to vibrations. The surface is remelted using a laser or electron beam.
