Columnar grain boundaries are the weakest link in hard coatings: Insights from micro-cantilever testing with bridge notches

Yinxia Zhang, Matthias Bartosik, Steffen Brinckmann +3

The effect of columnar grain boundaries on the fracture toughness was investigated using micro-cantilever fracture testing with a bridge notch, and a unique hard coating consisting…
