短碳纤维增强金刚石钻头铁基胎体性能的研究

Study on Iron-based Matrix Performance of Short Carbon Fiber Reinforced Diamond Bit

设计了粉末冶金法制备短碳纤维增强金刚石钻头铁基胎体材料,通过分析不同碳纤维添加量对胎体烧结性能的影响,得出在本实验制备条件下,短碳纤维对铁基胎体材料性能的影响规律,并对该结果进行了讨论分析,在此基础上,提出了制造更加优良短碳纤维增强铁基胎体材料的可能性。

Iron-based matrix composites was prepared by powder metallurgy for short carbon fiber reinforced diamond bit, based on the analysis on the influence on the sintering properties of composites with different carbon fiber addition quantity, the influence laws of short carbon fiber on the properties of iron-based matrix materials under this experimental preparing conditions were obtained.On the basis of the discussion on these laws, the possibility of more excellent short carbon fiber reinforced iron-based matrix composites developing is put forward.
