Abstract Scope |
In order to better understand the cold spray bonding process, it is necessary to experimentally assess the bond strengths of individual particle impacts. While there exist several techniques for this purpose in the literature, each possess limitations that restrict their usefulness. Some are too time intensive to gather enough data for statistical investigations, while others sacrifice measurement accuracy. We have previously proposed two novel techniques that exceed these limitations, each allowing for high throughput characterization while still maintaining high accuracy. One is a novel method of sample preparation that results in a sample geometry that is easy to test, while the other is a type of crack propagation test. In this work preliminary experiments are performed with both methods to evaluate and compare their effectiveness. |
