Temperature-Dependent Fracture Toughness Evaluation of WC-10Co4Cr Coating/1018 Low Carbon Steel Substrate System

Public Deposited
Resource Type
  • The temperature-dependent fracture toughness of WC-10Co4Cr coating/1018 low carbon steel substrate, which is a brittle coating/ductile substrate system, is evaluated at microscopic level with two types of models developed in terms of the Arrhenius type equation and rate controlling theory, utilizing indentation test data, in this research. One is based on the crystal structures of individual phases in the composite coating, the other considers the microcrack formation in the coating/substrate system under indentation loading.
