Offer Description

The low working temperature of cold spray technology offers a unique possibility to deposit a wide variety of composite materials by mixing two or more constituent powders. Materials that are sensitive to high temperature or to oxidation can easily be deposited by cold spray, without the challenges associated with other commonly used additive manufacturing techniques that are based on melting and solidification. However, there are still some issues to be resolved before we can gain full control of the deposit characteristics in cold spray. While it is possible to precisely control the chemical composition of the powder mixture before spraying, the compositional yield in the deposit remains uncertain. The compositional deviation with respect to the feedstock is mainly due to the differences in thermo-mechanical and morphological properties of different phases. Apart from that, the contribution of each phase to the mechanical performance of the integrated structure varies depending on their respective mechanical properties.

This PhD project plans to tackle these challenges and aims at defining cold spray design and evaluation procedures that lead to optimal structures made of two or more constituent phases. The project will account for the interaction of the dissimilar powders and estimates their respective contribution to the load-bearing capacity of the integrated structure.
