一种用高温高压合成的含硼金刚石复合片及制备方法
摘要：
一种用高温高压合成的含硼金刚石复合片及制备方法，含有以下步骤：步骤1；将含硼的金刚石微粉与硬质合金底板组合成合成块；步骤2；将合成块放在金刚石专用压机中在5.8GPa、1673K条件下烧结；步骤3；将合成后的含硼金刚石复合片的金刚石层磨平，抛光得到成品。一种用高温高压合成的含硼金刚石复合片，有硬质合金层和金刚石层，硬质合金层和金刚石层复合构成一体，金刚石层中含有硼元素，重量配比为：硼0.002－1.2％。本发明的优点在于硼是一种耐热、导电的材料。含硼金刚石复合片比普通的金刚石复合片具有更好的耐温性。
摘要（英）：

The invention relates to a boric diamond composite sheet synthesized at high temperature and pressure and a method for preparing the same. The method comprises the following steps that: in step one, boric diamond micropowder and a hard alloy base plate are combined to form a synthetic block; in step two, the synthetic block is put in a pressing machine specially for diamond and sintered under the condition of 5.8 GPa and 1,673K; and in step three, a diamond layer of the synthesized boric diamond composite sheet is ground and polished to obtain a finished product. The boric diamond composite sheet synthesized at high temperature and pressure is provided with a hard alloy layer and the diamond layer which are compounded into a whole; the diamond layer contains a boron element; and the weight ratio of boron is between 0.002 and 1.2 percent. The boric diamond composite sheet has the advantages that the boron is a heat-resistant and conductive material. Compared with a common diamond composite sheet, the boric diamond composite sheet has better temperature resistance.
