On the dependence of critical velocity on the material properties during cold spray process

Abstract

Optimization of the cold spray process is extremely challenging due to the involvement of a large number of process parameters as well as material properties. Modern approaches for modeling the cold spray process have relied largely on numerical simulations. In this paper, we shall present a simplified mathematical model which will be benchmarked against experimental and numerical measurements available in the literature and demonstrate that the model shows reasonable agreement with real-world observations. We will present a parametric study using this model and identify the factors that strongly affect the cold spray process, which can be used for identifying and optimizing the process parameters and the material properties.
