Abstract
In this investigation, the concepts of fracture mechanics are put to use to determine the adhesion strength of WC-Co coatings on metal substrates. The paper explains how test samples are produced and describes the procedures used to obtain fracture mechanics data. Adhesion strength is determined based on local energy release rates (crack closure integral method) and is verified using a finite element model of the test sample. With this approach, the spraying parameters for WC-Co can be more precisely tuned than would be possible with a frontal pull test. Paper text in German.
