Abstract:
The work presents the results of studies on the manufacture of multilayered ceramic shell molds the drying processes, including the selection of the proper slurries. The molds are intended for precision casting, especially in the aircraft industry [1-2]. The investigations included the selection of the optimum technological parameters of the casting slurries suitable for the first (inner) and structural layers of the mold, so that the entire surfaces of the wax mold models were covered uniformly with the successive layers (the first layer and seven structural layers) of specified thickness and porosity. The porosity of the layer was investigated by using computed X-ray tomography. By using a profilometer, surface roughness of the wax models and first ceramics layers were examined. Based on the conducted tests, it was found that the use of a thermal imaging camera enables precise determination of the drying time of the layers of ceramic shell molds.
