METHOD OF MANUFACTURE OF THE COMPOSITE WALL Russian patent published in 2008 - IPC B32B5/16 F23R3/00 

FIELD: chemical industry; motor industry; methods of production of the composite walls of the combustion chambers of the gas-turbine engines.

SUBSTANCE: the invention presents the method of manufacture of the composite wall for the gas-turbine engine. The method of manufacture of the composite wall made in the form of the "sandwich" type design containing the inner layer made out of the porous metal with the open pores bound with the inner covering layer and the outer covering layer, provides for manufacture of the base of the preset form inner layer made out of the gas-permeable porous material with the open pores. Then exercise the impregnation of the indicated base with the vapors of the metal and deposition of the porous metal layer on the open inner and outer surfaces of the base with formation by means of the process of the vacuum metallization of the inner layer made out of the porous metal with the open pores. Then they form the inner covering layer and the outer covering layer over the inner layer made out of the porous metal by means of the sputtering of the shell material selected from the group containing the metals and ceramics. The invention allows to diminish the cost of manufacture of the composite wall and to improve the operational characteristics of the combustion chamber of the gas-turbine engine.

EFFECT: the invention ensures reduction of the cost of manufacture of the composite wall, improvement of the operational characteristics of the combustion chamber of the gas-turbine engine.
