Application of Master Flow Curves in Modelling Powder Injection Moulding
Popis výsledku v původním jazyce
Rheological modelling of compounds used in Powder Injection Moulding is complicated due to complexity of the primary materials (so called feedstocks). Even for a description of shear viscosity a number of adequate models are rather low due to high concentration of nano- or micro-particles in feedstocks. The problem gets more complicated as presence of surfactant is required for better packaging of powder particles. Hence, shear viscosity does not depend solely on powder content but subjects to surfactant participation as well. In the present contribution a master curve is proposed for a description of shear viscosity of a feedstock (no parameters are required to be determined) over sufficiently broad regions of both aluminium powder and stearic acid as a surfactant. The deviation from the measured values does not exceed an experimental error.
