Description
技术领域
本发明属于材料学领域,具体地,涉及一种类地幔条件烧结聚晶金刚石复合片及其制备方法。
背景技术
金刚石为钻石的矿物学名称,在工业上,钻石主要用于制造钻探用的钻头头和机械加工用的切磨工具,形状完整的还用于制造手饰等高档装饰品,其价格十分昂贵。钻石即天然单晶金刚石。
天然单晶金刚石起源于数十亿年前的地球地幔深处,根据含金刚石的岩石可以推断天然单晶金刚石主要来源于地幔120千米~200千米深、压力约4GPa~5GPa,温度900℃~1300℃的高温高压环境。天然单晶金刚石在生长过程中某些岩浆成分被捕获而成为金刚石的包裹体。在世界各地均有发现金刚石矿,因此天然单晶金刚石内部包裹体的成分是各不相同的,现已发现的天然单晶金刚石主要存在于金伯利岩或钾镁煌斑岩岩石中,物质环境为富含挥发性成分的C-H-O流体或熔体环境,包括固态二氧化碳、碳酸盐、硅酸盐、石墨、结晶水及其它矿物等。
肼类化合物易溶于水,溶于乙醇,微溶于氯仿和乙醚。加热易分解,其最终分解产物为CH4,NH3,CO2,H2O等,未引入其他杂质,而这些小分子化合物在天然单晶金刚石的包裹体中是常见的物质成分,这些小分子也被认为是地幔成分中常见的成分,因此肼类化合物是研究氮、氢、氧共存环境下合成天然单晶金刚石理想的添加剂,如吉林大学郭龙锁《肼类有机物掺杂金刚石大单晶的高温高压合成及退火研究》(详见中国知网,学位论文库,吉林大学,2019年),是利用肼类有机物通过高温高压制备人造单晶金刚石。而人造单晶金刚石生长速度慢、合成时间长(通常需要几十甚至几百个小时),制造成本超过同样大小的天然单晶金刚石,要批量生产大颗粒单晶金刚石依然相当困难,并且单晶金刚石各向异性,其耐热性、抗冲击韧性、耐磨性均低于聚晶金刚石及聚晶金刚石复合片,用于工具领域极其有限,不能满足刀具及钻探领域需要。
聚晶金刚石是由金刚石微粉在高温高压条件下烧结而成的。聚晶金刚石中的细小金刚石晶粒随机错乱排列,整体各项同性,无解理面,且具有高硬度,高强度,高耐磨性等优良品质,并且由于有金属粘接剂的存在,聚晶金刚石的韧性也有所提高。聚晶金刚石复合片则是由金刚石微粉与硬质合金衬底在超高压高温条件下合成的超硬复合材料,具有极高的硬度、抗冲击韧性、热稳定性及耐磨性。聚晶金刚石复合片具有金刚石的硬度和强度性以及硬质合金基体材料的韧性和可焊接性,是一种优良的切削工具与耐磨材料,广泛地用于机械加工刀具、石油与地质钻探等领域。
