Silver water blocks

[Tacoman667]

If you were to use a silver water black with a copper radiator, would you get the galvanic corrosion like with copper/aluminum setups?

 

[phiber]

i think you would but i am not sure

I'm pretty sure that you would.

I am not sure what causes the Al/Cu problem? Well after think I think you may have the problem after all I remember soaking silver in a special container away from the copper container when I was doing metalworking.

good question. I am not too sure. I think there might be a problem but it would be less than that of the Al/Cu problem. Again, some water wetter and antifreeze shall work wonders.

 

[Tacoman667]

Why do you even have this problem with Al/Cu?

 

[William]

some anode cathode current thing going on. Thats all I know. But I do know that bad things can happen from this if you don't have water wetter or antifreeze in your system.

Starting with the most reactive and ending with the most noble. The farther apart the metals are the more they will react.

Mass also has an impact on the speed of corrosion. If there is more anodic material in the series than the noble, the process of corrosion will be slowed. If there is a greater material of noble (passive) material than the anodic the process will be accelerrated.

Thus, in a silver (block) and copper (radiator) series corrosion will take place. Albeit, at a slower rate than other combinations.

Using this little bit of knowledge you can see that potentially the worst combination would be an Aluminum block + Copper radiator.

Using something like zinc to act as a sacrificial anode would help alleviate the danger of the Aluminum from corroding. However, measures would have to be made to keep the zinc particles from clogging the system. A secondary reservoir with microfilters would probably work very well.
