| 中文摘要 | Synthesis of graphite films on 304 stainless steel (304SS) with and without multi-arc ion plated Cr and Ti coating by galvanostatic electroreduction of carbonate ions in molten 0.2Na(2)CO(3)-0.8NaCl (in mole fraction) has been investigated at 900 degrees C in argon gas, and the deposits were examined by scanning electron microscopy and Raman spectroscopy. The experimental results indicated that the carbon deposits obtained on both the Cr-coated and Ti-coated 304SS at the constant current density of 192 mA cm(-2) were continuous and exhibited a compact structure, with an excellent bonding with the substrate, while that obtained on the bare 304SS was porous and exhibited a poor adhesion to the substrate. Raman spectroscopy measurements showed that the carbon deposits on 304SS were mainly composed of amorphous carbon, with a small amount of graphitic crystallites, whereas the carbon films deposited on the Cr and Ti-coated 304SS consisted of well-crystallized graphite. The microstructure of ion plated coatings is helpful to the nucleation and growth of a well-crystallized graphite film. (c) 2012 Elsevier B.V. All rights reserved. |
