【 摘 要 】

The goal of this work is the description of phenomena occurring during centrifugal infiltration of porous ceramic materials by liquid Al alloy. In this method, the pressure required to infiltration of liquid metal into pores of ceramic is generated by centrifugal force. From the beginning it was assumed that the porous ceramic material will create reinforcement layer in specific area of the casting. The forces that influence on the liquid metal during mould centrifugation and heat exchange between ceramic preform and metal alloy within the area of the front of infiltration were considered in the analysis. The paper presents also selected experiment results.
