摘要

利用电化学噪声分析(ENA)研究了锌粉与铝或碳型填料复合改性ZRP对其防护性能可能产生的影响。在0.05 M NaCl中浸泡168小时，测试了不同的氧扩散特性(在测试的ENA涂层体系中确定)对分层倾向的影响。结果表明，不同类型的聚合物基体与Zn/Al或Zn/C颗粒组合向涂层/钢界面输送氧的能力不同，其防护性能随浸泡时间的变化有较大差异。

THE APPLICATION OF ENA FOR COMPARISON OF PROTECTIVE PERFORMANCE OF ZRP MODIFIED BY COMBINATION OF Zn DUST WITH ALUMINIUM OR CARBON TYPE FILLERS

The possible effects on the protective performance of ZRP modified by combination of Zn dust with aluminium or carbon type fillers were investigated using electrochemical noise analysis (ENA). The role of different oxygen diffusion characteristics (identified on tested coating systems with ENA) on delamination tendency was tested during 168 hrs immersion tests in 0.05 M NaCl. It was shown the protective performance of tested type of coating systems can be changing with immersion time rather differently in relation to different ability of polymer matrix with the Zn/Al or Zn/C particles combination for oxygen transport to the coating/steel interface.
