“…In contrast, the effect of standoff distance was the least influential on the track profiles in Figure 1c. With the larger standoff distance, the track profile became shorter and wider as observed in [31]. This phenomenon was previously confirmed by Pattison et al [45] and indicated that the standoff distance parameter space covered in this study was in the medium region near the optimal deposition efficiency point.…”

“…Meanwhile, the ANN modelling showed better predictive performance in the region of track profile edges than the Gaussian model. Such better predictive performance at profile edges was most likely due to the ANN model adequately capturing the complex multivariate nature of cold spray process (e.g., bow shock and compressed gas layer [47]), while this was observed to be lacking with the Gaussian model used previously in cold spray [24,31]. In summary, the comparative study of the two modelling approaches in Figure 4 showed that the ANN modelling possessed the potential to provide the prediction of detailed track profiles in CSAM at the same level of accuracy or higher.…”

“…In this study, three experimental process variables were selected as inputs to an ANN model: spray angle, traverse speed and standoff distance, together with other input variables subsequently introduced in Section 2.2. This selection was made based on previous studies, demonstrating their influence on the geometry of a track profile in CSAM [24,36] and precise control with a robotic system [37].…”
