中文摘要:
      采用接触反应法制备了原位TiC/Al-4.5Cu复合材料,研究了微观组织中TiAl3相对复合材料100-250℃高温下干摩擦磨损行为的影响。结果表明:高温下原位TiC/Al-4.5Cu复合材料磨损量均随载荷(15-55N)增加而增加,但含TiAl3相的复合材料磨损量始终较高。当载荷大于35N,复合材料存在一个磨损加剧的临界转变温度;含TiAl3相的复合材料该临界转变温度较低。TiAl3相的存在降低了复合材料的耐磨性。
Effect of TiAl3 Phase on Dry Wear Behaviorof In-situ TiC/Al-4.5Cu Composites at Elevated Temperature

英文摘要:
      In-situ TiC/Al-4.5Cu composites were made by direct reaction synthesis (DRS) and the effect of TiAl3 phase on the dry wear behavior of the in-situ TiC/Al-4.5Cu composites from 100℃ to 250℃ was studied. The results show that the wear loss of in-situ TiC/Al-4.5Cu increases with the load increasing from 15 to 55N at elevated temperature. The wear loss of the composites containing TiAl3 phase is always larger. There is a critical transition temperature (CTT) of severe wear when the load excesses 35N and the composites with TiAl3 phase possess lower CTT. TiAl3 phase degrades the wear resistance of in-situ TiC/Al-4.5Cu composites.
