The Potential of AE Sensing in the Indentation Fracture Toughness Measurement

Abstract:

In this study, an attempt is made to characterize the brittleness of the material by crack formation with the Vickers indenter. To assess the critical load, the sensor of AE signal was used. After preliminary tests on a silica glass, the methodology was applied to HVOF sprayed CrC-NiCr coating in as-sprayed and annealed state. The critical value of indentation force obtained from AE sensing was correlated with the standard method of crack length measurement with good agreement
