Abstract
A method and system for depositing multiple materials onto a substrate is described. The method broadly comprises the steps of providing a source of a first powder material to be deposited, providing a source of a second powder material to be deposited, and sequentially depositing the first powder material and the second powder material onto the substrate at a velocity sufficient to deposit the materials by plastically deforming the materials without metallurgically transforming the particles of powder forming the materials.

A method for depositing multiple materials onto a substrate comprising the steps of:
- providing a source of a first powder material to be deposited;
- providing a source of a second powder material to be deposited;
- sequentially depositing said first powder material and said second powder material onto said substrate at a velocity sufficient to deposit said materials by plastically deforming the materials without metallurgically transforming the particles of powder forming said materials.
A system for depositing multiple materials onto a substrate comprising a source of a first powder material to be deposited, a source of a second powder material to be deposited, and means for sequentially depositing the first powder material and the second powder material onto the substrate at a velocity sufficient to deposit the materials by plastically deforming the materials without metallurgically transforming the particles of powder forming the materials.
