The invention discloses a manufacturing method for an airspace engine
combustion chamber inner wall blank. The manufacturing method comprises the steps that S1, Cu, Cr and Zr materials are weighed; S2, the materials obtained in the step S1 is subjected to
vacuum induction melting, and an
alloy solution is obtained; S3, the
alloy solution obtained in the step S2 is poured to obtain an
alloy cast
ingot; S4, the alloy cast
ingot obtained in the step S3 is subjected to
forging, upsetting, drawing-out and
punching treatment, and a
combustion chamber inner wall blank is obtained; S5, the
combustion chamber inner wall blank obtained in the step S4 is subjected to
solid heat melting treatment; S6, the
combustion chamber inner wall blank treated in the step S5 is subjected to upsetting and secondary chambering treatment; S7, the treated
combustion chamber inner wall blank is subjected to rough turning, aging heat treatment, performance detection and finish turning treatment, and the
combustion chamber inner wall blank is obtained; and S8, size detection and appearance detection are conducted on the combustion chamber inner wall blank obtained in the step S7, and packaging is conducted. The manufacturing method for the airspace engine combustion chamber inner wall blank is reasonable in
process design, the obtained combustion chamber inner wall blank can meet the high-strength and high-heat-dissipation requirements of an airspace engine combustion chamber, and the manufacturing method is suitable for large-scale popularization.
