Abstract Scope |
In this work an in-situ method to monitor spray quality was developed to track where intentionally induced poor spray quality occurred. Cold spray plates were produced with and without intentional poor spray quality. Specimens were machined from both types of plates and tested under quasi-static uniaxial tension. This presentation will detail the development of a high throughput, automated method to detect the number of defects on the fracture surface of failed tensile specimens. First, a deep learning U-NET architecture was used to segment the images. Second, an unsupervised clustering approach was used to group different features of the fracture surface to isolate those that are characteristic of weak bonding due to the intentionally induced poor spray quality. It is anticipated that results from this work will be used to demonstrate that in-situ monitoring of the cold spray process can be used to supervise spray quality and part performance. |
