Fabrication and properties of 316L stainless steel/Y-PSZ composites
-
摘要: 采用粉末冶金方法制備了316L不銹鋼/Y-PSZ復合材料,研究了316L不銹鋼含量與粉末粒度對復合材料的顯微組織、燒結收縮率、密度及硬度的影響.結果表明:隨著316L含量的增加,復合材料的密度增高,相對密度和燒結收縮率逐漸降低,試樣的HRC硬度值下降;在316L含量一定的情況下,隨著316L顆粒尺寸的增大,復合材料的密度略有降低,相對密度和線收縮率逐漸減小,試樣的HRC硬度值下降.在本文的研究條件下,所制備復合材料的相對密度值在92.5%~95.5%之間.

Abstract: A kind of composite material of 316L stainless steel and Y2O3 partly stabilized zirconia (Y-PSZ) was prepared by powder metallurgic process. The effects of the content and size of 316L grains on the microstructure, relative density and hardness of the composite were investigated. The results showed that the relative density, shrinkage ratio and HRC value of the sintered samples decreased with the increase of 316L content. When the content of 316L kept constant, the relative density, shrinkage ratio and HRC value of the sintered samples decreased with the increase of 316L particle size. The relative density value was in the range from 92.5% to 95.5% in the present research conditions.-
