摘　　要：采用室温模压成形的方法制备了Cu-Sn-P高碳含磷铁基减摩材料,并研究了烧结温度、高温烧结时间及冷却时间对此种材料压溃强度和冲击值的影响。结果表明,影响压溃强度和冲击性能指标的第一因素,都是冷却时间,60min最佳;其次为烧结温度,压溃强度的最佳烧结温度在1 050℃,而冲击值的最佳烧结温度在1 030℃;高温烧结时间的影响相对较小,但都是20min最适宜。Cu-Sn-P high carbon containing phosphorus iron base antifrication materials was fabricated by room-temperature mold compaction formation method,and the influences of sintering temperature,sintering time and cooling timg on crushing strength and impact value of this material were studied.The results show that the first factor impacting crushing strength and impact performance index is the cooling time,60min is the best.Second factor is the sintering temperature,the best sintering temperature for Crushing strength is 1 050℃,but that for impact performance is 1 030℃;the influence of high temperature sintering time is relatively small,20 minutes is the most suitable sintering time.
