林伍德钻石材料技术，总部位于澳大利亚堪培拉，现在正在制造和销售，它声称的是最厚的可加工多晶钻石（PCD）紧凑型圆柱体 - 测量32mmØx 40mm（h）。大型圆柱PCD材料具有导电性，因此可以使用常规的电气放电加工（EDM）设备轻松地将其切成更复杂的3维形状。2020欧洲杯下注官网
Called DiaCom®, the diamond compact is in excess 70% diamond and the balance, silicon carbide binder. Sintered under a special set of pressure and temperature conditions, it is biocompatible due to the ‘Cobalt free’ manufacturing process and customers have reported the PCD material to be thermally stable to 1400° Celsius.
“Our unique patented sintering process enables DiaCom® to be cut and shaped into virtually any design our customers require,” said Len Kosharek, CEO, Ringwood Diamond Material Technologies. “This new degree of freedom will enable engineers, requiring a material with diamond like properties, the opportunity to develop application solutions, that up until now were unavailable due to size limitations of existing PCD material and its ability to be easily shaped”.
DiaCom® is already being used or tested in traditional PCD applications such as cutting tools, wear and bearing parts, oil and rock excavation and high pressure/high temperature research experiment apparatus.
Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) tested the performance of DiaCom® against three other PCD manufacturers in wear rate, wear resistance and length of cut trials. The results showed DiaCom® outperformed its nearest competitor in all tests.
CSIRO岩石切割和钻探技术研究小组经理Jim Boland博士说：“在磨损率测试中，Diacom®的表现是其最近的竞争对手的3倍。”“在我们进行的耐磨性测试中，DIACOM®至少达到了至少50％的耐磨性和更大的切割”。
预计直径尺寸（目前为32毫米）和高度（40mm）的组合将为新市场应用打开大门。
Ringwood Diamond Material Technologies鼓励所有有关方面的询问，讨论如何最好地使用DIACOM®来满足特定的应用需求。
