摘　　要：文章重点阐述了多元素合金(预合金)结合剂在金刚石绳锯串珠配方体系中的应用以及与单质结合剂之间的优劣对比。不同胎体结合剂对金刚石的把持力以及对金刚石的磨损度都不同,但均以粉末胎体工艺为核心,包括硬度、强度、致密度、浸润能力、磨损性及物相偏析等,同时还与多元合金的组员比例、物相结构、烧结温度、原料工艺波动等因素有关。通过相关对比试验,优质的多元素合金结合剂在烧结过程中稳定性强,烧结后组织性能好,对金刚石的浸润性及把持力较好。The article focuses on the application of multi-element alloy(pre-alloyed)binder in diamond wire saw bead formulation system and the comparison of advantages and disadvantages with single element binder.The holding power of different matrix binders on the diamond and the wear of the diamonds are different,but they all take the powder matrix process as the core,including hardness,strength,density,infiltration affinity,wear and phase segregation.At the same time,it is also related to the multi-element alloy composition ratio,phase structure,sintering temperature,raw material process fluctuation and other factors.Through relevant comparative tests,the high-quality multi-element alloy binder has strong stability in the sintering process,good microstructure and properties after sintering,and good wettability and holding power for diamond.
