氧化锆增韧氧化铝陶瓷增韧增强技术研究进展
Research progress in toughening and strengthening technologies of zirconia toughened alumina ceramics
摘要
Abstract
The coordinated improvement of toughness,strength,and hardness is important for expanding the applications of zirconia toughened alumina(ZTA)ceramics.Through literature research and comparison,this review analyzes the modification mechanisms of third-phase additives and sintering densification technologies for microstructure control.The results indicate that stabilizers can optimize phase transformation toughening.In-situ-formed platelet-like secondary phases can induce crack deflection and bridging.These mechanisms work together to improve fracture toughness.In terms of sintering processes,advanced technologies such as spark plasma sintering,oscillatory pressure sintering,and two-step sintering regulate densification kinetics by suppressing grain coarsening and eliminating closed pores.This regulation helps optimize hardness and toughness.Furthermore,densification kinetic models clarify the effects of zirconia on the grain growth exponent and sintering activation energy.By summarizing the synergistic mechanism of compositional optimization and process regulation,this review provides a reference for preparing dense,fine-grained ZTA ceramics with enhanced mechanical properties.关键词
