RHEOLOGICAL AND THERMAL DEGREASING CHARACTERISTICS OF NOVEL FORMATIVE AGENT

Zhou Jicheng, Huang Baiyun, Wu Enxi, Qu Xuanhui and Li Yiming State Key Laboratory for Powder Metallurgy, Central South University of Technology, Changsha 410083, P. R. China  
Rheological and thermal degreasing characteristics about several kinds of novel formative agent system used for hardmetal powder extrusion molding have been studied deeply. The formative agent's design and its mixing decide their rheological properties and degreasing behaviours. The formative agent's components and formulations which have been selected carefully and reasonablely are the key to the new PEM(powder extrusion molding) technology. Under the experimental conditions, the formative agent's microstructures are homogeneous phase; the viscous flow activation energies are 80~115 kJ·mol -1 ; the formative agent's viscosity is little dependent on temperature, and the formative agent's thermal removal rates are also even during the degreasing temperature range. These properties are very useful for the technical control.
