This study investigates a new evaluation method that has the potential to differentiate between particle interfaces and grain boundaries in cold spray coatings. The method uses confidence index (CI) and image quality (IQ) values obtained from EBSD analysis to determine the location of grain boundaries as well as grain orientation and crystallinity of the deposit. In the case of a cold-sprayed copper deposit, the new method helps to explain the observed characteristics of the coating.
