Diamond-cubic boron nitride composite sheet and preparation method thereof
The invention provides a diamond-cubic boron nitride composite sheet and a preparation method thereof.The diamond-cubic boron nitride composite sheet is composed of titanium coating diamond micro-powder, pure diamond micro-powder, cubic boron nitride micro-powder and cobalt powder, the titanium coating diamond micro-powder is added, the cubic boron nitride micro-powder is added according to a certain proportion, and the titanium coating diamond micro-powder and the pure diamond micro-powder are evenly mixed; therefore, the diamond-cubic boron nitride composite sheet with better temperature resistance is obtained. The diamond-cubic boron nitride composite sheet obtained in the invention has toughness, wear resistance and temperature resistance, and has good conductivity, and the heat-resistant temperature of a cutting tool can be obviously improved when the diamond-cubic boron nitride composite sheet is made into the cutting tool; and during high-temperature vacuum welding, the welding temperature range can be greatly increased, the vacuum degree condition can be greatly reduced, and the probability of graphitization is reduced.
本申请提供了一种金刚石‑立方氮化硼复合片及制备方法，其中的金刚石‑立方氮化硼复合片由钛涂层金刚石微粉、纯金刚石微粉、立方氮化硼微粉和钴粉组成，加入钛涂层金刚石微粉，并按一定比例加入立方氮化硼微粉，从而获得耐温性能更好的金刚石‑立方氮化硼复合片。本申请获得的金刚石‑立方氮化硼复合片兼具韧性、耐磨性与耐温性，并具有很好的导电性，在做成切削刀具时可以显著提高刀具的耐热温度；在高温真空焊接时，也会大幅度增加焊接温度范围和降低真空度条件，减少石墨化的概率。
