Aqueous electrophoretic deposition as a method for producing an investment casting shell mould ceramic face-coat. Part 1: formation of a carbon-filled investment casting wax electrode material

This paper is the first to address the formation of carbon-filled investment casting wax composite electrode materials as a step towards confirming the feasibility of developing aqueous electrophoretic deposition (EPD) as a promising technique for forming the investment casting shell mould ceramic face-coat. In contrast to other studies focussed on carbon-polymer composites that used a single polymer matrix, or a paraffin wax matrix, this work employed modern investment casting waxes, which are very complex low-melting point designed-for-purpose materials containing numerous components, as a matrix. This added a further complicating factor to the carbon-wax composite behaviour analysis.
