将WC-8Ni硬质合金中的粘结剂用不同比例的纳米镍Ni粉替代,采用常规硬质合金的工艺制备出合金试样,测试其物理力学性能,研究不同比例的纳米Ni粉及不同的烧结温度对合金性能的影响.结果表明,在适当比例的纳米镍粉及烧结温度下,合金的性能得到很大的提高.

The binder of WC-8Ni cemented carbide was partly substituted by the nanometer Ni powder. Samples of cemented carbide were made by means of traditional technology, and their physics and mechanical properties were tested. The influences of nanometer Ni powder content and sintering temperatures on the physical and mechanical properties of the alloys were studied. The results indicated that the properties of alloys were greatly increased under certain proportions of nanometer Ni powder and sintering temperatures.
