Solvent debinding process for ZK60 magnesium alloy mim compact

Abstract

The influence of the leaching temperatures on the solvent debinding process of ZK60 magnesium alloy compact has been investigated. In this experiment, the soluble binder, palm stearin molecules were extracted out from the compact parts by immersing the compact parts in an n-heptanes solution. The solvent debinding rate was then investigated under the conditions of different leaching temperatures. The weight loss percentages of palm stearin were calculated and the pore structure evolution was analyzed by scanning electron micrograph. Results show that a complete diffusion of the palm stearin molecules out of the compact part best at 60° within 4 hours of extraction time. © 2012 Penerbit UTM Press.
