This study investigates the influence of columnar grain boundaries on the fracture toughness of nitride hard coatings using in situ SEM microcantilever fracture tests with bridge-notch geometries. Fracture behavior was evaluated under different loading directions—parallel and perpendicular to the coating growth. Results indicate that notches aligned perpendicular to the grain boundaries increase fracture toughness by approximately 10% due to crack deflection. Additionally, fracture toughness in columnar-grained regions was over 30% lower compared to epitaxially-grown microstructures, highlighting the need for grain boundary toughening to enhance the performance of hard coatings.

Nanoindentation mapping is an ideal technique for correlating mechanical properties with local chemistry and microstructure but suffers from the slow process of manually aligning separately measured maps. Here, we discuss the PI 89 Auto Picoindenter, a system designed to streamline the process of correlating microstructure with mechanical properties using an automated, high throughput in situ nanoindentation testing method. The system is used to assess the microstructure via electron backscatter diffraction (EBSD) and energy dispersive spectroscopy (EDS) before rotating toward the nanoindenter probe for nanomechanical mapping. We will discuss the processing-structure-mechanical property relationships in structural materials measured with this system.
