Abstract

PURPOSE: To provide highly free selection of material and facilitate groove molding of complicated shape by spraying molten metal particles after having stuffed filling material into grooves on the periphery of a liquid rocket engine combustion chamber and then removing the filling material, thus forming cooling grooves.
CONSTITUTION: A plurality of grooves 13 are formed on the periphery of a cylindrical member 12 which constitutes a combustion chamber for rocket engine. Filling material 14 is stuffed into the grooves 13. The filling material 14 can resist against frame spraying and can be also removed easily after flame spraying. After stuffing the filling material 14, molten metal particles are sprayed to the periphery of the cylindrical member 12 by flame spraying and plasma spraying to produce a metal layer 16, while rotating the cylindrical member 12. Then the filling material 14 is melted and removed by applying heat, aqueous solution or organic solution, thereby forming cooling grooves.
