摘要
本文对含微量硼铜的蠕墨铸铁性能进行试验研究,并与合金铸铁性能对比分析。结果表明硼铜蠕墨铸铁具有高的耐麿性、耐热疲劳性和更好的综合性能。生产成本低,生产过程易控制,是具有实用价值的新生铸铁材料。
The behaviour of a vermicular cast iron containing trace amounts of B and Cu was investigated and compared with that of a Cr - Mo-Cu cast iron. The results show that the B-Cu vermicular cast iron has high resistances to wear and thermal fatigue,and it possesses better comprehensive performance and lower production cost. Besides, its production process is easy to control. The material shows a promising future in practical application.
