Everything and Anything About Galvanic Corrosion
Today, we will talk about galvanic corrosion, a factor which triggers rusting and which is more likely to occur without ample
rust prevention methods.
To some people, this may be a familiar term but to most, “galvanic corrosion” remains an alien word. So today, we are giving you as much information that you need – everything and anything about “galvanic corrosion.”
What's galvanic corrosion?
It is the process where two metals get in contact with each other – electrochemically in the process of an electrolyte. When this happens, one of the metals which is the anode corrode faster than its normal speed if it were left alone and the other metal, this time the cathode, corrodes slower.
What triggers the formation of galvanic corrosion?
-
A high temperature can cause less resistance to the electrolytes; thus causing galvanic corrosion.
-
The anode size as compared to the cathode – when the anode is larger than the cathode, the lesser the corrosion.
-
An intense electrical contact between the two metals – this increases the risk of galvanic corrosion.
How do you avoid galvanic corrosion?
The first thing to bear in mind is to separate two metals which are in close proximity to each other. To this, you need to separate the metals electrically through either of the following processes:
- - You can separate the metals using plastic.
- You can also separate metals using grease.
- Electroplating using chrome, nickel, silver or gold will also be a big help.
- Protect your metals using a sacrificial cathode.
Keep yourself aware about rust and its triggering factors. It's not enough to find out the best way to remove rust, focusing on prevention is still high encouraged.
