An axial flow compressor blade unit including a platform section and an airfoil section, which are used as arranged on a circumference about an axis of the compressor. The platform section includes an inner diametric surface segment inwardly of the circumference, an outer diametric surface segment outwardly of the circumference, two annular side surface segments extending in a circumferential direction, two axially side surface segments extending in the axial direction, and a coupling portion formed in each of the annular side surface segments so as to extend in the circumferential direction and being of a shape projecting or recessed in the axial direction. The airfoil section is formed to erect from the platform section so as to extend in a radial direction. The platform section and the airfoil section are formed integrally with each other while having a powdered metal sintered structure.

Blades for axial flow compressor and method for manufacturing same

A plural number of types of material powders are accommodated in an accommodation chamber in a mixed state and the material powders are continuously subjected to a self-exothermic reaction inducing chemical reactions between the material powders caused by heat of reaction released when the mixed material powders synthesize. The synthesized material of high temperature due to the self-exothermic reaction is pressed by utilizing an electromagnetic force just after the finish of the self-exothermic reaction. The exothermic reaction is caused by an ignition circuit including an ignition electrode and the electromagnetic force is generated by an electromagnetic force generation circuit including an electric current inducing means. These circuits are connected through and regulated by a relay circuit. Thus the synthetic products of fine structure are obtained.
