Abstract

The morphology and composition of an oxide layer on the surface of iron chipping cuts obtained using metal-working under conditions of intense plastic shear deformation and subsequent thermal oxidation have been investigated by scanning electron microscopy with an X-ray probe, Raman spectroscopy, and thermogravimetry. It is shown that agglomerations of metal–oxide nanoparticles and nanostructures (whiskers, nanotips, and nanoleaves), which are promising for production of new composites with ultra-fine-grained metal–oxide filler, are formed with a high rate on the surface of metal chippings during annealing in air at 800°C. The economic and ecological benefits due to recycling of metalworking wastes for producing new metal–oxide nanomaterials and related composites appear to be significant.

塑性变形铁屑氧化过程中金属氧化物纳米结构的形成

摘要

通过X射线探针扫描电子显微镜，拉曼光谱和热重分析，研究了在强烈的塑性剪切变形和随后的热氧化条件下，通过金属加工获得的铁屑切屑表面氧化物层的形态和组成。 。结果表明，金属氧化物纳米颗粒和纳米结构（晶须，纳米尖端和纳米叶）的附聚物以很高的速率形成，这些附聚物有望用于生产具有超细颗粒金属氧化物填料的新型复合材料。在800°C的空气中退火期间金属碎屑。回收金属加工废料以生产新型金属氧化物纳米材料和相关复合材料所带来的经济和生态效益似乎很显着。
