<p>Post-treatment is essential to tailor performance and enhance the durability of cold-sprayed coatings. Typically, particles deposited in a solid state with high kinetic energy experience a high level of work hardening and require heat treatment to facilitate structure improvement by residual stress relief, a decrease of porosity or alloying. However, conventional furnace treatments impose limitations on the dimensions of the sample and involve significant energy consumption. Therefore, the use of directed infrared radiation as an alternative post-treatment approach eliminates geometrical restrictions and enhances overall energy efficiency. In this study, the effect of infrared treatment on low-pressure cold-sprayed coatings of elemental Cu and Al powders with Al₂O₃ was investigated. The parameters of near-infrared treatment were power, stand-off distance, and heating time. The post-treatment caused the formation and growth of intermetallic compounds at the Al/Cu interfaces, which were analyzed using XRD, scanning electron microscopy, light microscopy, and hardness measurements. The findings of this study contribute to the evolving post-treatment strategies for cold-sprayed coatings, offering a promising avenue to improve efficiency and overcome limitations associated with traditional furnace treatments.</p>
