Method for creating functionally graded materials using cold spray

摘要

A method and system (10) for depositing multiple materials onto a substrate (12) is described. The method broadly comprises the steps of providing a source (14) of a first powder material to be deposited, providing a source (16) of a second powder material to be deposited, and sequentially depositing the first powder material and the second powder material onto the substrate (12) at a velocity sufficient to deposit the materials by plastically deforming the materials without metallurgically transforming the particles of powder forming the materials.
