THE SPRAY-FORMING OF THIN WALL SHAPES

The works described in this paper are part of a general study concerni ng new methods for the realization of parts of turbo-engines and turbo -pumps; the results presented concern the superally INCONEL 625. At fi rst are presented the metallographic structure of the deposits and sec ondly test-pieces developped in order to characterize their mechanical properties (i.e. NOL-Rings, tubes,...). The physical and mechanical p roperties of the sprayed and heat treated materials are then compared with those of forged and sintered materials. The performances of the s prayformed test-pieces was observed to be similar to the forged or sin tered ones.
