Abstract
Aspects include supplying a plurality of nickel-enriched braze powder particles to a cold spray system through a particle supply inlet. The nickel-enriched braze powder particles are accelerated through a transfer tube and out an exit in the transfer tube towards a substrate to produce a braze cold-sprayed substrate. A component surface is positioned proximate to the braze cold-sprayed substrate. The braze cold-sprayed substrate is heated to bond the braze cold-sprayed substrate to the component surface.
Claims13
A method comprising:
- supplying a plurality of nickel-enriched braze powder particles to a cold spray system through a particle supply inlet;
- accelerating the nickel-enriched braze powder particles through a transfer tube and out an exit in the transfer tube towards a substrate to produce a braze cold-sprayed substrate;
- forming a hole in the braze cold-sprayed substrate;
- positioning a component surface proximate to the braze cold-sprayed substrate and within the hole;
- and
- heating the braze cold-sprayed substrate to bond the braze cold-sprayed substrate to the component surface.
A method comprising:
- applying a magnetic field to a braze alloy powder to remove a quantity of nickel from the braze alloy powder;
- combining a nickel powder with the braze alloy powder to form a nickel-enriched braze powder;
- processing the nickel-enriched braze powder to deform a plurality of finer particles and produce a plurality of nickel-enriched braze powder particles;
- supplying the nickel-enriched braze powder particles to a cold spray system;
- and
- accelerating the nickel-enriched braze powder particles in the cold spray system towards a substrate to produce a braze cold-sprayed substrate.
