Abstract

Volumetric structures consisting of multilayer clads made of the bronze B10 and also of stellite SF6 alloys are prepared by laser remelting of the metal powder of the original particle size of ca 60 micrometers injected into the processing zone through a conical nozzle. For remelting with a cw CO₂ laser beam of intensities around 10⁵ W/cm² and sample feed rates not exceeding 2.5 cm/s an efficient formation of the structures is observed and their geometry can be controlled. A fine grained, dendritic microstructure of the samples is observed by means of the optical and scanning microscopes. In the AFM scans the characteristic dimension of ca 60 nm reproduced in the periodic structures of the SF6 surface corresponds most probably to crystallines formed due to segregation after the liquid-solid phase transition. Similarly to SF6 the powderized B10 material is well suited for a fast prototyping.
