Manufacturing process of composite plates made of magnesium alloys and ceramic foam and composite plates

摘要

Process bases on the infiltration of metal melt (matrix) in the pores of ceramic foam (hardening phase). Method of casting, sizing of mould, preheating of ceramic foam or mould, pouring temperature, use of insulating cover and vibrating enable complete filing the pores with metal. For manufacturing of composite plates the gravity casting and vibrating of total system during casting and solidification is used. Such composite plates are used in automotive, aircraft and military industry because composite plates have good mechanical properties, high break-through strength at low density and resistance to cutting.
