METHOD OF PRODUCING ARTICLES FROM COMPOSITE POWDERS Russian patent published in 2013 - IPC B22F3/105 

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of articles from powder materials in layer-by-layer laser fritting. It may be used for making complex-shape composite parts. Powder is fed by proportioning container composed of a set of cells with outlets. Powder is displaced vertically by vibration onto every cell of said proportioning container at specified frequency of 0.1-0.5 kHz. Powder compacter composed of a roller is displaced over location surface to compact the powder. Laser is displaced to preset position defined by appropriate computer model to fuse the powder so that preset-depth functional layer is formed. Laser radiation power equals 100-120 W, laser displacement speed equals 4-6 mm/s and laser beam diameter equal 4-6 mm.

EFFECT: expanded range used powders and process performances.
