Multi-component deposits

A method comprising:

• cold spraying first particles and second particles of a same metal alloy on at least a portion of a surface of a substrate to form a deposit on the surface of the substrate,
• wherein the first particles form a first component of the deposit and the second particles form a second component of the deposit,
• wherein cold spraying comprises accelerating the first particles and the second particles toward the surface of the substrate at a temperature below a melting point and a transition temperature without melting and without creating other thermally induced changes to a microstructure of the respective first and second particles,
• wherein the first and second particles have been subjected to different heat treatments prior to cold spraying,
• wherein the first component and the second component are non-homogeneously distributed throughout the deposit,
• wherein a tensile strength of the first particles is at least about 10% greater than a tensile strength of the second particles, and
• wherein a percent elongation of the first particles is at least about 10% greater than a percent elongation of the second particles.
