A Study on The Electrochemical Behavior of CF/Al Composite in Aqueous Solutions
- 발행 : 2011.05.19
초록
In this work, The electrochemical behavior of CF/Al composite was investigated at constant current densities in aqueous solutions. The surface and cross section of PEO-treated CF/Al were observed using SEM, EDS and OM. The CF/Al composite contains carbon fibers of about 40 Vol.% with 5~7 um diameter and 100~150 um length. The carbon fibers appeared to b removed by anodic oxidation in sulfuric acid solution, leaving a carbon-fiber free zone in the surface region. Anodic oxide films were formed in the carbon-free region by plasma electrolytic oxidation(PEO) method in alkaline solutions.
