Description
Technical field
The invention belongs to field of ocean engineering, specifically the on-the-spot corrosion electrochemical test system in a kind of deep-sea and method of testing thereof.
Background technology
Marine environment is a kind of corrosion environment of harshness, and the metallic structures such as port installations, oil platform, subsea pipeline, marine ship, deep sea vehicle all must think over the etching problem that marine environment brings in design and use process.In order to grasp corrosion behavior and the rule of various materials in marine environment; for the exploitation of design, selection, protection and the new material of fixing or mobile ocean steel construction provides basis and foundation; the corrosion test that must carry out real extra large environment, accumulates the corrosion data of various materials in practical service environment.At present, the corrosion test in surface seawater has all been set up test method and the technology of standard both at home and abroad, and the corrosion behavior to metal material in surface seawater and rule have also had more deep understanding, have accumulated the basic data of a large amount of preciousnesses.Yet, due to the complicacy of deep-marine-environment, the material Deep sea corrosion test within the scope of our times carry out also seldom, the deep-sea corrosion data of China is blank substantially.
