Research Status and Prospects on Ceramic Core Materials for Investment Casting
Ceramic core is a kind of ceramic material used in investment casting technology,and its performance directly determines the quality of casting.Ceramic core has a series of advantages,such as desirable wear resistance,superior sealing,high strength,and long service life,which is widely used in aerospace,automotive manufacturing,electronics,and electrical fields.According to the matrix material,ceramic core is mainly divided into silicon oxide-based ceramic core,alumina-based ceramic core,and magnesium oxide-based ceramic core.The performance of ceramic cores prepared with different matrix materials is also varied.Based on the research results of ceramic core matrix materials,the current research status on ceramic core materials for investment casting was summarized in detail from the aspects of influencing factors of ceramic core performance,core detachment,and the advantages and disadvan-tages of different ceramic core materials,in order to provide a basis for the design and investigation of ceramic core.
