СПОСОБ ИЗГОТОВЛЕНИЯ ДЕТАЛИ ЦЕНТРОБЕЖНОГО НАСОСА

摘要

FIELD: powder metallurgy, possibly manufacture of complex construction parts of centrifugal pumps. ^ SUBSTANCE: method comprises steps of making separate joined parts, namely guiding sleeve with blades and body. Sleeve is produced by casting process; body is sintered from powder material. Formed parts are mutually joined along joined surfaces by means of diffusion welding at simultaneously impregnating pores of sintered material. ^ EFFECT: simplified process for making parts with complex -profile blades without deterioration of their mechanical properties. ^ 1 dwg, 1 ex
