Mechanistic study of superlattice-enabled high toughness and hardness in MoN/TaN coatings

Transition metal nitride coatings exhibit high hardness, but typically lack ductility and are therefore prone to failure. Here, the effect of bilayer thickness on the mechanical properties of MoN-TaN superlattices is investigated, leading to coatings with high fracture toughness.
