Theoretical model of intrinsic hardness
Webb11 feb. 2024 · The GR (001) interface model is placed between the coating TiAlSiN and matrix WC-Co, and the models of coating/matrix interface doped with intrinsic and defective graphene of TiAlSiN/WC-Co are constructed. The orientation relationship is TiAlSiN (111)/GR (001)/WC (0001)-Co. Webb15 juli 2011 · The hardness of the two polymorphs was evaluated based on the methods proposed by Sung and Gao et al. Although the bulk modulus of phenakite is small the results indicate that it is a relatively hard material. On the other hand, the spinel structure is a super hard phase.
