This Small Business Innovation Research (SBIR) Phase I project will further develop a prototype high pressure/high temperature apparatus, which will be capable of generating pressures of 10-30 GPa at 2000-5000C in mm3 volumes. Having realized this objective, samples of high quality single crystal and polycrystalline diamond by controlled crystallization from a high purity carbon melt will be prepared and evaluated. This will substantiate the unique capabilities of the apparatus. Concurrently functionally-graded nano-TiC/WC/Co and nano-diamond/WC/Co anvil materials will be prepared.This new class of superhard/tough materials as well as the process to fabricate them at high rates will have applications including punch and die sets, wire drawing dies, forging blanks, drill bits, machine tools for example.

该小型企业创新研究（SBIR）第一阶段项目将进一步开发一种原型高压/高温装置，该装置将能够在2000- 5000 ℃下以mm 3体积产生10-30 GPa的压力。实现这一目标后，将通过从高纯碳熔体中控制结晶来制备和评价高质量单晶和多晶金刚石样品。这将证实该装置的独特能力。纳米TiC/WC/Co和纳米金刚石/WC/Co功能梯度顶坚韧材料及其高速制备技术将在冲压模具、拉丝模、锻坯、钻头、机床等领域得到应用。
