Micromechanical characterization of coated PCBN inserts

, 2020
Polycrystalline cubic boron nitride (Pc-BN) is a super-hard material with a multiphase composite character. Indeed, it is a composite material composed of c-BN particles (as reinforcement) embedded in a binder (ceramic or metallic), mainly used as a cutting tool material.
