Synthesis, characterization and application of the filler based on corundum for obtaining the ceramic coats in foundry
Abstract
In this work, a possibility to develop new ceramic coats based corundum for casting applications has been examined. Optimization of coating composition with controlled rheological properties was attained by applying different coating components, and by alteration of coating production procedure. As filler, corundum powder with particle size of 20x10(-6) m and 40x10(-6) m was used. The corundum sample was tested by the following methods: X-ray diffraction analysis and with polarized microscope. The shape and grain size were analyzed by the program package OZARIA 2.5. It was shown that application of this type of water-alcohol-based coating had a positive influence on surface quality, structural and mechanical properties of the castings of Fe-C and Al alloys obtained by casting into sand molds, according to the method of expandable patterns (EPC process).
