Here's an example of galvanic corrosion between carbon steel and aluminum in sea water:
When two different metals are coupled together in atmosphere or water, the likelihood of developing galvanic corrosion can be predicted using a “galvanic series.” In specialized applications, such as when dissimilar metals are embedded in concrete, corrosion data for that specific environment should ...
If they are not compatible, the chance of suffering galvanic corrosion becomes very real. Galvanic corrosion occurs when metals are incorrectly combined and exposed to water and other electrolytes. In this scenario the metal with a lesser nobility will become susceptible to corrosion. For harsh ...
Galvanic corrosion behavior of A 516 steel coupled to alloy C-22 and Ti Gr-12, respectively was evaluated in an acidic brine (pH {approx} 2.75) at 30 C, 60 C and 80 C using zero resistance ammeter method. A limited number of experiments were also performed in a neutral brine involving...
2.Thecouple corrosionof the two metal materials in a completion fluid,a mixed salt water of salinity up to 300 g/L,are investigated experimentally and the proper inhibitor is selected.实验研究了两种钢材在完井液 (盐含量高达 30 %的溶液 )中的电偶腐蚀并筛选了缓蚀剂。
mechanical fatigue, galvanic corrosion, dealloying, etc., are the common types of corrosion by which materials in desalination plants are subject to ... Anees,U.,Malik,... - 《Desalination & Water Treatment》 被引量: 21发表: 2012年 Corrosion investigation of Cu-Ni tube desalination plant Co...
The external corrosion of the top plates is mainly atmospheric corrosion orelectro-chemical corrosioncaused by the waste water. 罐顶外壁主要为大气腐蚀或因废水引起的电化学腐蚀 ,其内壁为因结露而引起的电化学腐蚀 ;罐底内侧沉积水中含有H2 S ,CO2 ,Cl-和泥砂引起点蚀 ;罐底外侧为潮湿环境下引起的电化学...
In your case, the bronze part is smaller, it is attached to a comparative larger CS component, so chance of Galvanic Corrosion is negligible. Also, as the parts will not be submerged in water, possibility of Crevice Corrosion is remote (as some Galvanic Corrosion would still occur in the ...
