FIELD: technological processes.
SUBSTANCE: invention is related to machine-building, in particular, to working blades. Foliated systems according to hardware level do not have efficient cooling against external hot gas. Foliated system (1) that corresponds to invention contains external porous layer (10), at that walls of pores (22) and pores (25) have different thickness of walls of pores (22). Production method consists in the fact that porous layer is produced layer-by-layer in several partial steps.
EFFECT: improvement of cooling for foliated system in protection against excessively high heat introduction.
