Abstract

Warmup of mechanically activated Ti–xC powder mixtures (x = 1.0, 2.1, 4.2, and 6.3 wt %) in a furnace preheated to 800°C was found to result in thermal explosion (volume reaction) in mixtures with x = 4.2 and 6.3 wt %. Activated powder mixtures and combustion products were characterized by XRD, optical metallography, and SEM/EDX. Combustion products represented metal-matrix Ti–TiC composites containing different amounts of strengthening agent. Our results may turn interesting to those engaged in deposition (cladding) of protective Ti–TiC coatings using reactive Ti–C mechanocomposites as a starting material.

在机械活化的 Ti-xC 粉末混合物中通过热爆炸制备 Ti-TiC 复合材料（x = 1.0-6.3 wt %）

摘要

发现在预热至 800°C 的炉子中加热机械活化的 Ti– x C 粉末混合物（x = 1.0、2.1、4.2 和 6.3 wt%）会导致x = 4.2 和6.3 重量％。活化的粉末混合物和燃烧产物通过 XRD、光学金相和 SEM/EDX 进行表征。燃烧产物代表含有不同量增强剂的金属基体 Ti-TiC 复合材料。我们的结果可能会对那些使用反应性 Ti-C 机械复合材料作为起始材料来沉积（包覆）保护性 Ti-TiC 涂层的人感兴趣。
