3YSZ陶瓷在等离子作用下的快速晶粒长大
Ultrafast Grain Growth of Plasma-treated 3YSZ Ceramics
摘要
Abstract
Zirconia has broad application prospects in the industry,but unlike metal materials,it is difficult to control the microstructure and improve mechanical properties of ceramics through post heat treatment.This article proposes a plasma treatment technique at room temperature and studies the effects of plasma treatment and applying current on the microstructure of ceramics,achieving grain size control of dense 3YSZ(3mol％yttria stabilized zirconia)ceramics.The results indicate that plasma treatment can promote the grain size of 3YSZ ceramics from submicron(0.45 μm)to tens of microns(＞90 μm)in a short period of time.Applying current has a promoting effect on the rapid grain growth of ceramics.When the current is 1.0 A,the maximum grain size of zirconia can reach 255 μm,which is approximately 565 times larger than the initial grain size.The rapid grain growth caused by this plasma treatment can be attributed to the enrichment of oxygen vacancies induced by the electric field and the influence of plasma action on the rapid migration of grain boundaries.Compared with traditional heat treatment,plasma treatment technology has the advantages of high efficiency and low energy consumption,providing new ideas for ceramic microstructure control and single crystal material preparation.关键词
