Powder injection moulding of a ceramic part
Hausnerová, B. ; Marcaníková, L. ; Filip, Petr
The aim of the study is to optimize the production of alumina ceramic parts via Powder Injection Moulding (PIM) technology. As a case study fabric with main demand on surface-roughness tolerances has been selected with the potential of high production quantities for textile machines industry. The process is searched in terms of material tailoring, part design and dimensions, and processing conditions of injection moulding, debinding and sintering steps. Rheological, thermal and pressure-volume-temperature characteristics were measured in order to provide the reliable data for the simulation of injection moulding as well as thermal and thermogravimetric analyses have been carried out to attain non-porous final sintered products.
Electric properties of composites of hard metal carbides in polymer matrix
Vilčáková, J. ; Sáha, P. ; Hausnerová, B. ; Quadrat, Otakar
Electric conductivity of composites of hard metal carbide powder in a non-conducting polymer matrix at high filler concentration, where flow instabilities of the melted composites were observed, has been studied.
