中文摘要:采用混料设计方法,研究了WC、YG8、663-Cu含量变化对WC基复合胎体抗弯强度的影响规律。3种成分含量变化对抗弯强度有显著性影响,呈线性模型关系,得出了相应的回归方程。三者之间的影响大小是YG8>WC>663-Cu;3种成分含量变化对强度损失率影响很小,通过调整三者的成分比例,无法有效地提高胎体对金刚石的把持力。

Properties of WC-based composite matrix by mixture design
Abstract:The effect of the content changes of WC, YG8 and 663-Cu on the bending strength of the WC based composite is investigated by the mixture design. The content changes of the three components have significant effects on the bending strength of the matrix with or without diamonds, and the effects exhibits linear model relations. The related regression equations are obtained, and the order of the effect of the results is as follows: YG8>WC>663-Cu. Besides, the content changes have less effects on the bending strength loss rate, indicating that the diamond retention cannot be effectively improved by adjusting the proportion of WC, YG8 and 663-Cu in WC based composites.
