Why not fastener corrosion all about rust?

Mar 08, 2018

When you are going to buy or use fasteners, you may be worried about corrosion. When your fasteners are eventually corroded, they tend to become difficult to disassemble and may even damage the items you originally fastened. This means that before you even order them, it is wise to devise measures to ensure that you never have to deal with these problems. Some common, including the use of non-corrosive fastener materials, or have gold-plated fasteners. You can also paint with special materials to reduce corrosion.

One thing you need to keep in mind when doing all this is that corrosion is not limited to rust. Although rust is the most common form of corrosion, there are many other types that can have similar effects that you also need to keep in mind. The effect of taking them for granted is the same as letting rust damage your fastener. Other types of corrosion include:

General corrosion

This is a form of corrosion that occurs evenly on the surface of the fastener. It is usually caused by electrochemical processes that eventually lead to rust. One of the main advantages of this form of corrosion is that it is predictable, which means you can use several methods to prevent it. It is also easy to manage; you don't have to spend too much money to control it. Some of the strategies you can use include electroplating fasteners or keeping them away from humidity.

Galvanic corrosion

This is a corrosion that occurs when two different metals of the electrochemical charge are in contact with each other. Over time, there are electrons moving from one metal to another due to the difference in charge. This leads to a chemical reaction similar to rust. This eventually leads to the weakening and damage of the fastener. The best way to prevent this from happening is to use fasteners, which are close to the items fixed on the charge. The best way is to make sure that both are the same charge, although this is not always possible.

Caustic soda Corrosion

In this form of corrosion, gases or liquids dissolve in water to form a compound that has strong oxidation properties, such as hydrogen sulfide. When these compounds come into contact with fasteners, they react and cause damage. The degree of damage usually depends on the duration of the contact, as well as the chemical properties of the corrosive and fastener. For example, fasteners made of aluminum or platinum may not react much to most corrosive agents.

These are just a few types of corrosion; there are many other things to consider when choosing fasteners. The best way to do this is to involve knowledgeable people in the selection process.
