What You Need To Know About Pitting Corrosion

By Christopher Kelly


Certain projects that cost time and energy include acquiring the materials for the job. In the case of building or creating a certain device, one of the most popular items that most experts generally work with is metal due to its stability and flexibility. However, certain cases may test this strength to the core which can lead to safety risks. Here are some interesting facts regarding rust pitting.

The first thing we need to know first is its definition. Pit corrosion refers to damage in a particular area of a metal. Its defining characteristic is the fact that it looks like a collection of holes or pits, thus making the surface look hollow and unsafe. Considering that it starts at a molecular level first, it may be hard for users to detect early signs of damage until it is too late.

There are several factors that can attribute to the cause of this issue. Regardless of how stable or durable your material is, the number one factor that causes pitting is the environment where natural processes can break down the components of your metal. Some examples of items easily susceptible to this phenomenon include stainless steel, stainless alloy, and aluminum alloy to name a few.

To expand on the environmental factor, this includes chemical and mechanical damage to the protective oxide film. For chemical factors, this could either be due to excess acidity, high concentrations of chloride, and low dissolved oxygen concentrations. Since they target at a chemical level, most often find it hard to detect the first signs of damage.

Last is using a combination of both metal and nonmetal materials. Nonmetal components like wood are often fragile to extreme weather conditions which are why they are often combined with more stable materials like stainless steel. However, this does not guarantee overall safety since neither is able to compensate each weakness thus resulting in more cavities to form.

When left ignored for too long, corrosion can lead to a number of safety hazards. For instance corroded roofs can invite harmful air, increased moisture levels, and even rodents to get inside your home, while damaged bridges may lead to vehicular accidents, dents, and even topple over if it is built over a body of water. Some of which have been recorded in history as a precautionary tale.

In order to prevent these instances, users are expected to follow a series of preparatory steps during construction. This includes choosing the right material to work with during your project to ensure the best possible finish. For instance, picking materials with higher alloy reduces the chances of corrosion unlike low alloy materials which have a higher risk.

With this in mind, it is safe to say that users should be extremely careful when preventing corrosion. One way to do so is to select the right materials and look for options that are less susceptible to chemical damage. Additionally, they will need to conduct a thorough research on this so they can choose the best option available.

Pit corrosion can lead to a lot of dangers if not taken care of properly. Considering that most injury occurs beyond surface level, one does not immediately notice some of its early stages of said problem until it is too late to recover from it. To prevent this, clients are expected to follow reliable safety measures while also seeking counsel from an expert contractor.
