Abstract
A laser deposition apparatus includes a sealed enclosure configured to hold a substrate, a powder source configured to hold a powder material, a peen source configured to hold a shot peen media, and a deposition system fluidly connected to the powder source and the peen source. The deposition system includes a laser configured to generate a laser beam. The deposition system is configured to deposit at least one layer on the substrate by injecting a stream of the powder material into the laser beam. The deposition system is configured to shot peen the at least one layer by propelling the shot peen media onto an exterior surface of the at least one layer.

A laser deposition apparatus comprising:
- a sealed enclosure configured to hold a substrate;
- a powder source configured to hold a powder material;
- a peen source configured to hold a shot peen media;
- and
- a deposition system fluidly connected to the powder source and the peen source, the deposition system comprising a laser configured to generate a laser beam, wherein the deposition system is configured to deposit at least one layer on the substrate by injecting a stream of the powder material into the laser beam, the deposition system being further configured to shot peen the at least one layer by propelling the shot peen media onto an exterior surface of the at least one layer.
A method for laser deposition comprising:
- depositing at least one layer of material on a substrate by injecting a stream of a powder material from a powder source into a laser beam using a deposition system that is connected to the powder source and is connected to a peen source;
- and
- shot peening the at least one layer of material by using the deposition system to propel a shot peen media from the peen source onto an exterior surface of the at least one layer of material.
A laser deposition apparatus comprising:
- a laser configured to generate a laser beam;
- and
- at least one deposition head configured to be fluidly connected to a powder source that contains a powder material and a peen source that contains a shot peen media, wherein the at least one deposition head is configured to deposit at least one layer of material by injecting a stream of the powder material from the powder source into the laser beam, the at least one deposition head being further configured to shot peen the at least one layer by propelling the shot peen media from the peen source onto an exterior surface of the at least one layer of material.
