摘要：
Ceramic molds containing the ZrSiO4/SiO2 primary face coat with and without addition of cobalt aluminate were produced. After firing, the surface and the cross sections of the face coats were subjected to detailed characterization using XRD, SEM and EDS. The interaction between the mold systems and 0.9C-6W-5Mo-4Cr-2V high-speed steel was studied during the gravity and vacuum investment casting. During casting, the isostructural transformation of the initial ZrSiO4 filler occurred. For the mold without addition of the cobalt aluminate, two different types of interaction products [multicomponent phase containing O, Al, Zr, Fe, W and V and (Fe, W,Mo,Cr)2Al2O6)] were revealed. An interaction layer of a depth in the range of 5-30 μm was thoroughly studied after casting into the mold containing the cobalt aluminate. Addition of the cobalt aluminate into the ceramic system provided significant refinement of the high-speed steel microstructure.
