| 摘 要： | 采用粉末冶金方法制备了316L不锈钢/Y-PSZ复合材料,研究了316L不锈钢含量与粉末粒度对复合材料的显微组织、烧结收缩率、密度及硬度的影响.结果表明:随着316L含量的增加,复合材料的密度增高,相对密度和烧结收缩率逐渐降低,试样的HRC硬度值下降;在316L含量一定的情况下,随着316L颗粒尺寸的增大,复合材料的密度略有降低,相对密度和线收缩率逐渐减小,试样的HRC硬度值下降.在本文的研究条件下,所制备复合材料的相对密度值在92.5%～95.5%之间.

| 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. |
