Abstract
The works described in this paper are part of a general study concerning new methods for the realization of parts of turbo-engines and turbo-pumps ; the results presented concern the superalloy INCONEL 625. At first are presented the metallographic structure of the deposits and secondly test-pieces developped in order to characterize their mechanical properties (i.e. NOL-Rings, tubes,...). The physical and mechanical properties of the sprayed and heat treated materials are then compared with those of forged and sintered materials. The performances of the sprayformed test-pieces was observed to be similar to the forged or sintered ones.
