A Probabilistic, Semi-empirical Approach to Modeling Diffusion Bond Strength

Year: 2000

Type: article

Abstract: Manufacture of critical diffusion bonded components could benefit from predictive models of diffusion bond joint strength. Existing models focus on porosity closure, which is a necessary but not sufficient condition for acceptable joint strength. The present work identifies modeled dynamics intrinsic to manufacturing but not captured in existing models. Controls regulating these dynamics are proposed, and the topography of real engineering surfaces is described by distribution functions. Pore closure kinetics then can successfully link initial surface topography and final porosity distribution, which in turn correlates to joint strength given experimental data linking porosity to joint strength.
