摘　　要：研究了在金刚石表面熔盐镀覆Ti,镀Ti层的物相为TiC和Ti,创建了“金刚石-TiC-Ti”镀Ti层结构模型。提出了金刚石的脱落度和胎体材料对金刚石的把持力系数的新概念。使用一般金刚石与使用熔盐镀Ti金刚石的金刚石锯片相比,金刚石的脱落度由72.2%降至32.3%,减少39.9%;胎体材料对金刚石的把持力系数由75.6%增至92.81%,提高了17.21%。Ti-plated diamond surface by molten salt was investigated. The phases of Ti-plating are TiC and Ti, and diamond-TiC-Ti structure model of Ti-plated diamond surface was established. The desquamating grade of diamond and the holding force coefficient between matrix and diamond were suggested as new concepts. A comparison of the diamond saw blade using ordinary diamond with that using Tiplated diamond reveals that the desquamating grade of diamond reduces from 72.2% to 32.3% , representing a decrease of 39.9% ; the holding force coefficient between matrix and diamond increases from 75.6% to 92.81% , an increase of 17.21%.
