| Abstract: | To fabricate the metal-ceramics multi-layer hollow functionally gradient materials(FGMs) that might meet the requirement of repeated service and long working time of high temperature burners, such as spacecraft engine, the microstructure and properties of composite of stainless steel and partially stabilized zirconia were investigated. Samples of different proportions of stainless steel to partially yttria-stabilized zirconia were fabricated by powder extrusion and sintering method. Shrinkage, relative density, microstructure, micro-Vickers hardness, compression strength, bending strength, fractography morphology and electrical resistivity of sintered samples with different proportions of stainless steel were measured. The results show that threshold of metallic matrix composite(MMC) is approximately equal to 60%(volume fraction) stainless steel. The samples with 0 to 50%(volume fraction) stainless steel indicate ceramic brittleness and non-cutability, and the samples with 70% to 100%(volume fraction) stainless steel indicate metallic plasticity and cutability. |
