研究了稀土元素对Ｎｉ代Ｃｏ硬质合金性能的影响。结果表明，稀土元素可使ＷＣ－８％Ｎｉ硬质合金的性能大大提高，因而使其可以在许多领域取代传统的ＷＣ－Ｃｏ硬质合金。
The effects of rare earth elements on the performance of Ni-based Co cemented carbide were studied. The results show that the rare earth elements can greatly improve the performance of WC-8% Ni cemented carbide, making it possible to replace the traditional WC-Co cemented carbide in many areas.
