Abstract Titanium hydride powder was used to completely or partly replace the spherical titanium powder in order to reduce the cost. The microstructure and mechanical properties after debinding and sintering were investigated. The results showed that with the addition of the titanium hydride powder, the microstructure gradually changed. The fabricated alloy was a titanium matrix composite reinforced with in-situ TiC particles. With the increase in the proportion of titanium hydride powder, the catalytic debinding percentage decreased, which led to an increase in the concentration of carbon and oxygen, and hence, there was a decrease in the tensile strength and elongation though the density of titanium MIM samples increased. The hardness and wear resistance increased as compared with those for pure titanium materials in the market. These results provide a promising method for reducing the cost of titanium MIM, and development of great industrial application prospects.

添加氢化钛粉对钛粉注射成型组织和性能的影响

摘要 为了降低成本，采用氢化钛粉来完全或部分替代球形钛粉。研究了脱脂和烧结后的显微组织和力学性能。结果表明，随着氢化钛粉的加入，显微组织逐渐发生变化。制造的合金是用原位 TiC 颗粒增强的钛基复合材料。随着氢化钛粉比例的增加，催化脱脂率降低，导致碳和氧浓度增加，因此钛MIM样品的拉伸强度和伸长率降低增加。硬度和耐磨性较市场上纯钛材料有所提高。
