一种整体烧结聚晶金刚石球齿及其制备方法
摘要：
本发明公开了一种整体烧结聚晶金刚石球齿，所述球齿由外部耐磨层和内部抗冲击层组成，外部耐磨层位于内部抗冲击层的外层，外部耐磨层由以下质量分数的原料制成：金刚石微粉70-95%，镍粉1-5%，硅粉1-15%，钴粉3-20%；内部抗冲击层由以下质量分数的原料制成：金刚石微粉40-70%，镍粉1-10%，硅粉5-15%，钴粉10-40%。本发明针对未来发展需求，提出了整体烧结聚晶金刚石球齿，这种材料的原材料是人工合成的，并且随着技术的进步，其价格也在不断降低，因此未来将有很大前景。
摘要（英）：

The invention discloses a whole sintered polycrystalline diamond spherical tooth. The spherical tooth is composed of an external abrasion-resistant layer and an internal impact-resistant layer. The external abrasion-resistant layer is located on the outer layer of the internal impact-resistant layer. The external abrasion-resistant layer is made of raw materials of, by mass, 70-95% of diamond micro-powder, 1-5% of nickel powder, 1-15% of silica powder and 3-20% of cobalt powder. The internal impact-resistant layer is made of raw materials of, by mass, 40-70% of diamond micro-powder, 1-10% of nickel powder, 5-15% of silica powder and 10-40% of cobalt powder. The whole sintered polycrystalline diamond spherical tooth aims at future development demands, a raw material of the whole sintered polycrystalline diamond spherical tooth is artificially synthesized, and as the technology progresses, the price is also decreased, so a great prospect is achieved in the future.
