METHOD OF SINTERING PARTS FROM POWDERS

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to powder metallurgy, particularly to laser layer-by-layer synthesis. It can be used in machine building to produce complex solid parts from powders to increase their quality and efficiency. Powder metered portions are fed onto working chamber table, powder layer being burnished thereafter. Working chamber is evacuated and laser beam is focused on powder layer. Focused laser beam is moved at preset rate to sinter part sections in layer and mutually perpendicular grid lines that form cells and zones in sintered section. Laser is readjusted and defocused laser beam is used to sinter part section area, light beam diametre and radiation powder being increased. ^ EFFECT: higher efficiency and quality. ^ 2 cl, 1 ex
