Abstract for Patrick R. Taylor / University of Idaho / CTS-9220252 The PIs propose to produce very fine carbide and boride particles by the techniques of plasma synthesis. They propose to develop a fundamental understanding of the reaction kinetics, heat and mass transfer, and nucleation and growth kinetics associated with the generation of these particles using a modified previously developed non-transferred arc plasma flow reactor. Once these fine particles are obtained, they will be characterized as to their strength, hardness, and toughness produced by the sintering and hot isostatic pressing of the particles. The PIs further propose to develop a theoretical model capable of describing the nucleation and growth phenomena in these plasma systems.

爱达荷州大学帕特里克·R·泰勒/CTS-9220252的研究人员建议用等离子体合成技术生产非常细的碳化物和硼化物颗粒。他们建议对使用以前开发的改进的非转移弧等离子体流动反应器产生这些粒子的反应动力学、热量和质量传递以及成核和生长动力学有一个基本的了解。一旦获得这些细小颗粒，就会对它们的强度、硬度和韧性进行表征，这些强度、硬度和韧性是通过颗粒的烧结和热等静压产生的。PI进一步建议开发一个能够描述这些等离子体系统中的成核和生长现象的理论模型。
