In the opinion of metrologists, technologists and trybologists surface microgeometry is one of the most important factors affecting the performance characteristics of the machine parts (resistance to wear, sliding and lubricating properties, durability and tightness of joints, fatigue strength, corrosion resistance, etc.). The analysis was made of the ceramic mould elements structure influence on the microgeometry of steel castings surface and their dimensional accuracy. To assess the structure of the ceramic mould previous studies made with usage of computer tomography where used, those studies highlight the ceramic mould structure anisotropy and its properties.
