Abstract
A process for the production of high temperature-resistant metallic components with finely porous walls through which there can diffuse a cooling medium. The component is formed of an alloy capable of oriented eutectic solidification, and is cooled in a controlled mode after short-term sintering so as to form needles or rods extending perpendicular to the wall surfaces, and which are then etched out so as to provide cooling medium passageways.
Claims8
A process for producing high temperature-resistant metallic components of complex shape having finely porous walls, particularly such facilitating the diffusion therethrough of a cooling medium, comprising the steps of:
- (a) imparting the configuration to said component from an alloy adapted for oriented eutectic solidification;
- (b) effecting a short-term sintering to said component and controlled cooling so that the solidification propagation extends perpendicular to the wall surfaces, including wall surfaces of complex shape;
- (c) and etching out formed needles or rods from the solidified component.
