Materials Science Sacrificial Cathodes— Experiments on a Boat or Down Pipelines Rust is the enemy. Rust is a damage done by water & air in metal. As rust grows, breakage and hidden, complicated function errors can occur. That is why sacrificial anode and impressed current cathodic protections are crucial! It can be used in boats to prevent rust and keep pipes clean, which means they will last much longer.
First, you need to find out what metal your boat or pipeline is made of. It is crucial as different metals will rust at different rates. Once you know what the metal is, you can pick a sacrificial cathode of a more reactive metal. What does that mean? It would rather sacrifice the cathode so your boat or pipeline metal does not. This way, your boat or pipeline is safe!
But you may be wondering why we would even need to use iccp systems in the first place, right? Well, there are several great things to prevent rust here. The main benefits are the protection of your boat from rust and the safety of using pipes. These are all items that can be protected or enhanced by using a sacrificial cathode so they will not break easily and continue to work for years.
Yet you also need to realise that there are disadvantages to using sacraficial cathodes as well. This sacrificial cathode will be eroded over time and will need to be replaced, for example. This means that you need to have a regular check of it and keep it well-maintained. You will need to check on it at regular intervals and replace the same as required.
Sacrificial anodes are particularly well-suited to applications where the workpiece is submerged in a conductive electrolyte, such as seawater. Rust is huge in the world of water. It is exposed to water for a long time hence causing its continual rust. That is where sacrificial cathodes like those sold by Mace come into play they serve to inhibit such rust and keep your bits from being destroyed!
Sacrificial cathodes on boats are typically made of a metal known as zinc. Most boats and pipelines are not made from metal that is as reactive as zinc. This indicates that the sacrificial cathode will corrode and erode away well before the metal in the boat or tube is, as a result safeguarding both those objects from danger.
So, now you know what sacrificial anodes and how they work, it is little wonder that how vital they are for stopping boats and hulls and pipes from rusting. They might sound like a scary, fancy term, but sacrificial cathodes are actually just a… something? that can help make things work gooder for longer.
