The Development of a New Type Aluminium Anode for Deepwater Cathodic Protection

Abstract:

Article Preview

The electrochemical behaviour of a new type Al-Zn-In-Mg-Ti-Ga-Mn anode suitable for deepwater cathodic protection was investigated. The current efficiency experiment was carried out in various simulated deepwater environment, and the EPMA and SKP technologies were also used. The results showed that the anode had uniform dissolution morphology in simulated deepwater environment. The current efficiency was always higher than 90% in all the experiment conditions.
