摘要：

为了提高碳化钨（WC）基复合胎体材料的性能，在烧结压力为13 MPa、升温时间为6 min、保温时间为5 min的情况下，采用真空热压烧结的方法制备了金刚石钻头所用的10种不同比例WC基胎体材料试样30块，并对试样进行了洛氏硬度(HRC)、抗弯强度(σ)等性能测试。通过试验数据分析研究了WC、663青铜(ZQSn663)、锰(Mn)、钴(Co)、镍(Ni)与胎体材料HRC和σ的关系。结果表明：WC质量分数对胎体的HRC和σ的影响是主要因素，胎体的HRC和σ具有内在联系，HRC高的胎体σ往往也高；在胎体配方中各个成分的含量都应得到控制才能保证胎体的性能优良，各成分的质量分数控制为：w(WC)<59.1%, w(ZQSn663)>25%, 3%<w(Ni)<6.5%, 0.9%<w(Co)<3.5%, w(WC-ZQSn663)<20%。

Abstract:

For getting better properties of WC matrix composites, the performance such as the rockwell hardness and bending strength, etc. of 30 WC matrix composites, prepared by 10 different formulas, are tested. These samples were manufactured by the vacuum hot-pressing sintering process using intermediate-frequency furnace under the conditions that sintering pressure is 13 MPa, the heating time is 6 min, and the holding time is 5 min. The influence of WC, copper ZQSn663, Mn, Co, and Ni on the hardness and bending strength properties of matrix are investigated by data analysis. The results indicate that WC is the prime factor to influence the hardness and bending strength of matrix. Internal logic exists between the hardness of matrix and bending strength. The matrix with high hardness has high strength, too. To get excellent performance of the matrix, the proportion of elements by weight should be controlled in formula: WC<59.1%, ZQSn663>25%,3%
