Popis Nowadays used hard protective coatings are often based on ceramics. They generally exhibit high hardness and high stiffness, however, these positive features are often accompanied by negative brittle deformation behavior. If a crack is formed, it can easily and rapidly spread which can lead to a sudden premature failure of the coating as well as the whole coated tool. The current trend in surface engineering is to sacrifice some of the hardness in favor of enhanced ductility and fracture toughness.
