Abstract
Powder-based additive manufacturing processes for producing integral parts with multiple metallic materials are disclosed. The integral parts are printed as single pieces by joining different metallic materials together during printing. A combination of different powder-based additive manufacturing processes or the same process can be used to produce the integral part.
Claims20
A multi-material part for a combustion device, comprising:
- an injector plate penetrated by at least one propellant channel, wherein the injector plate comprises a copper based alloy;
- a propellant manifold configured to provide a propellant to the at least one propellant channel, wherein the propellant manifold comprises a nickel based alloy;
- and
- a diffusion region between a portion of the injector plate and a portion of the propellant manifold, wherein the diffusion region comprises a gradient of compositions between the copper based alloy and the nickel based alloy.
A method for additively manufacturing a multi-material part, comprising:
- depositing, using a first print system, a first metallic material comprising a copper based alloy on a build plate to form an injector plate penetrated by at least one propellant channel;
- and
- depositing, using a second print system, a second metallic material comprising a nickel based alloy on the injector plate to form a propellant manifold configured to provide a propellant to the at least one propellant channel, such that the part is printed as an integral piece;
- wherein a diffusion region is formed between a portion of the injector plate and a portion of the propellant manifold, and wherein the diffusion region comprises a gradient of compositions between the copper based alloy and the nickel based alloy.
