爆轰聚晶金刚石微粉

多晶金刚石，又称聚晶金刚石，多晶钻石。多晶金刚石通过爆轰法合成，其颗粒晶体结构与天然的Carbonado极为相似，通过不饱和键结合成多晶体结构。 与单晶金刚石相比，聚晶金刚石有更多的晶棱和磨削面，每条晶棱都具有切削能力，因此有很高的去除率。聚晶金刚石具有自锐性和韧性，在抛光过程中，粗颗粒会破碎成更小的颗粒，可避免对工件表面造成划伤，而新的裂面具有更多锋利的切削棱，既保证了工件表面质量，又提高了研磨切削效率，在某些高质量要求的产品加工过程中显示出它独特的优越性。 ● 具有类似Carbonado的结构外形特征，外观灰黑色，略呈金属光泽 ● 高耐磨性和使用寿命长 ● 粒度型号齐全，包括微米级、亚微米级和纳米级的粒度 ● 产品质量稳定，批次之间差异小 ● 能够达到超高纯度，主要杂质含量在100ppm以下 ● 保持较高的切削能力的同时，能够达到高精密的抛光效果，不易产生划伤

Polycrystalline diamond (PCD) is similar with natural Carbonado in the structure. Compared with monocrystalline diamond, PCD has more cutting edges, resulting in the higher removal rate, with good self-sharpening properties. The structure will always open new sharp edges introduced by releasing an outer layer of dull crystallites. The polycrystalline diamond can give higher removal rate and lowest level of scratches. That’s why it is especially suitable for the high precision processing on super hard material
● Keep high removal rate and precision polishing effect without scratches. Especially suitable to ultra-hard material as non-ferrous metals, alloys, tungsten carbides, sapphire and other wear parts
● Compared with monocrystalline diamond powder, polycrystalline diamond with high toughness, and good self-sharpening properties
● High wear ability and long service life
