Modification of PEG/PMMA Binder by PVP, for Titanium Metal Injection Moulding
Powder Technology, 2017Co-Authors: Muhammad Dilawer Hayat, Steven Matthews, Aparajita Goswami, Tao Li, Xiaowen YuanAbstract:Abstract Polyethylene glycol (PEG), with polymethyl methacrylate (PMMA) as the Backbone Binder component, is a common primary Binder component in the design of water soluble Binder systems for metal injection moulding (MIM). However, PEG crystallises upon cooling, producing voids in the injection moulded parts. These voids ultimately lead to porosity and degraded mechanical properties in the sintered bodies. We have previously reported on the use of polyvinylpyrrolidone (PVP) as a crystallisation inhibitor in the PEG/PMMA Binder system to suppress void formation. In this paper, PEG/PMMA/PVP Binder-based feedstocks were prepared with a 67 vol% solid loading in order to evaluate the effects of PVP incorporation on the PEG/PMMA Binder for titanium MIM. The homogeneity and rheological behaviours of the feedstocks with varying amounts of PVP were compared with the base PEG/PMMA Binder-based feedstock. Microstructural observation, impurity measurement and mechanical testing were carried out. It was found that incorporation of 20 wt% PVP into the PEG produced a void-free, high quality Ti-MIM component, with an average final density of 98% and a tensile elongation of 9.5%.

Polyolefin Backbone Substitution in Binders for Low Temperature Powder Injection Moulding Feedstocks
Molecules, 2014Co-Authors: Berenika Hausnerova, Ivo Kuritka, Davit BleyanAbstract:This paper reports the substitution of polyolefin Backbone Binder components with low melting temperature carnauba wax for powder injection moulding applications. The effect of various Binder compositions of Al2O3 feedstock on thermal degradation parameters is investigated by thermogravimetric analysis. Within the experimental framework 29 original feedstock compositions were prepared and the superiority of carnauba wax over the polyethylene Binder Backbone was demonstrated in compositions containing polyethylene glycol as the initial opening agent and governing the proper mechanism of the degradation process. Moreover, the replacement of synthetic polymer by the natural wax contributes to an increase of environmental sustainability of modern industrial technologies.
