Description

一种表面粗糙金刚石的合成方法 技术领域
本发明涉及一种表面粗糙金刚石的合成方法。
 背景技术
金刚石微粉具有高硬度、高耐磨性和良好的耐腐蚀性能，这些优良特性使其在诞生之初就成为研磨与抛光领域的宠儿。天然金刚石俗称钻石，多少世纪以来一直是一种最昂贵的宝石，象征着高贵、美丽、圣洁与永久，然而美丽的钻石所散发的绚丽色彩却离不开研磨与抛光。初期，人们试图用其它材料实现钻石的抛光，只因钻石既硬又耐腐蚀，可谓刀枪不入，这时金刚石微粉应运而生了。进入工业时代以后，金刚石微粉已不仅仅用于钻石抛光方面，她已广泛用于国民经济的各个领域。例如在石材行业，金刚石微粉做成软磨片、精磨片用于石材的表面抛光；木材行业中，金刚石微粉做成的精密砂轮用于木工刀具的修整；汽车行业中，金刚石微粉做成的绗磨条用于缸孔、曲轴孔、连杆孔以及其它零件孔类的加工；光学领域中，金刚石微粉做成的精磨片、超精磨片用于光学镜头的加工；石油开采及地质勘探中，金刚石微粉做成的金刚石复合片是钻头的牙齿；机床加工中，金刚石微粉做成的金刚石复合片替代传统的硬质合金，成为刀头利刃；金属加工中，金刚石微粉成为金属表面精密抛光的优良材料。因此，金刚石微粉在多个领域均得到广泛应用。但是，随着科技的不断进步，对研磨抛光的加工提出了越来越高的要求，主要表现在两点：高效与高精。传统的金刚石微粉是单晶结构，颗粒表面较为平滑，切削刃数量少，切削力弱；单个颗粒切削刃大而硬，划伤严重；同时受到外力冲击时沿解理面碎裂， 粒度很快变小，研磨寿命短。IT行业中，硬盘及磁头需要非常高的表面光洁度和平整度；光通讯中光纤连接器端面抛光后粗糙度Ra值在纳米级，LED行业中蓝宝石晶片的研磨抛光不但要求很强的切削力，而且要求晶片表面无划痕，这些要求传统的单晶金刚石微粉已经无法实现。
 技术问题
目前，表面粗糙的金刚石颗粒通常是对金刚石进行处理得到的，例如：美国专利US12560899，申请日为2009.09.16，公开了一种不规则的表面，其中的粒子的表面粗糙度小于约 0.95 磨料颗粒。一种生产方法改性磨料颗粒，其中包括提供多个磨料颗粒，所述粒子上提供无功的涂层，加热所述包覆的颗粒 ；和恢复修改磨料颗粒，然而其制作工艺复杂，工业生产效率低。

　　3）在金刚石生长完成及相对压力下降接近于0但保持顶锤与合成块有很好的接触，控制温度在800~1250℃，保持60~180min；或者，在金刚石生长完成后，将HPHT合成柱状物取出放入真空炉中加热至800~1250℃，保持60~180min；
　　4）将合成柱状物取出，去除残留的石墨和催化剂，在通过清水清洗和通过分级干燥或干燥后打筛将金刚石颗粒进行按不同力度后目数分类，得到不同粒度的粗糙表面的金刚石。
　　进一步，标准HPHT工艺用催化剂和石墨重量比为0.75:1 ~1.5:1，比如，1:1。
　　作为一种优选方案，步骤3）中控制温度较佳在1100℃。
　　作为另一种优选方案，步骤3）中控制温度最佳在1050℃。
 有益效果
