Summary: | 碩士 === 國立中央大學 === 能源工程研究所 === 100 === Debinding is the most important process in the MIM. An improper debinding process will lead to damage in finished products.
To analyze the residual saturation and liquid bridge phenomenon among particles in different working parameter, e.g., binder’s property, particle’s gap and diameter, navier-stokes equations and level set method are applied to simulate the debinding process in this research. Results show small viscosity and large surface tension lead to low residual saturation, and large gaps result in low residual saturation too. If particle’s diameter is too large or small, it will yield high residual saturation. The binders bounded in particles neck region are affected more by gap and particle’s diameter rather than by binder property, large gap and small diameter yield larger pore in the subdomain and result in a small irreducible saturation.
