并对影响制备材料性能的因素进行了分析.研究结果表明:在熔渗温度为1 500 ℃、熔渗高度为6 mm时
最佳熔渗保温时间应为30 min; 随着制备试样中Ti
相的逐渐增多
材料的抗弯性能明显提高; 随着试验压力的增加
Ti
材料的摩擦因数和磨损率均呈现先增加后减小的趋势
在试验压力为30 N时摩擦因数最大
压力为40 N时磨损率最大; 摩擦表面连续氧化膜的生成有助于减轻Ti
材料的磨损.
material was prepared with infiltration-sintering technology
and the performance influence factors of Ti
were analyzed. The results show that: at infiltration temperature of 1 500 ℃ and infiltration height of 6 mm
the best infiltration holding time is 30 min; Flexural strength of the sample increases with the increasing Ti
phase; friction factor and wear rate of the sample first increase and then decrease with the increasing pressure
and the friction factor and wear rate get the maximum when the pressure is 30 N and 40 N
respectively; and the continuous oxide film is of benefit to reducing wear and tear of Ti
material.
