低钴含量梯度硬质合金钎片的研究

Research on the Properties of Gradient Cemented Carbide Mining Bits with Low Cobalt

研究了平均钴质量分数为6.5%在钎片体内呈梯度变化分布的硬质合金的机械性能和使用性能。结果表明它有较好的机械性能和凿岩性能 ,且成本较低 ,可以替代传统的YG9C和YG11C牌号硬质合金钎片。

This report is about the mechanical properties and applications of cemented carbide mining bits with a 6.5% cobalt in gradient distribution. Results show that they have good mechanical and mining properties with low cost. It is a good substituent of YG9Cand YG11C grade cemented carbide mining bits.
