Resum
In this work we describe an energy-based window of deposition, and predict the deposition efficiency for different cold-sprayed powder/substrate systems, using machine learning techniques. We implement several machine learning models to predict whether particles adhere or bounce off during cold spraying. The models are trained using data extracted from several experimental runs taking into account the cumulative particle size distribution and the deposition efficiency of the process. The classification models infer a critical total energy threshold above which deposition occurs. Based on this threshold, we describe an energy-based window of deposition for the powder/substrate systems studied. These models predict the deposition efficiency of different spraying operations for different powder materials with acceptable accuracy. Machine learning techniques provide better understanding of the particle deposition process and enable a more comprehensive exploration of the scope of cold spraying. The use of these techniques opens up new possibilities for the pursuit of links between the spraying process, the structure and different properties for novel cold-sprayed materials.
