Corrosion is the deterioration of a material caused by environmental interactions. One of the common forms of corrosion is rust. Corrosion is converting the reactive metal surface into a more stable form, like its oxide, hydroxide, or sulfide. In corrosion, the reactive metal surface is converted into a more stable form. Corrosion is having a variety of negative effects on metal and it can be a common cause behind accidents.
What are the factors leading to corrosion?
Corrosion is caused by gases, solutions, and electrolytes. It is the chemical attack on a material leading eventually to its destruction. It occurs in different forms depending on the material under corrosive attack. Corrosion, also known as rust, leads to safety problems and it ruins the integrity of the equipment. The deterioration of metal or material is due to the electrochemical reaction occurring on the metal surface. The type and quality of corrosion determine the rate of corrosion on the material.
The electrochemical reaction is appearing in several forms, like chemical corrosion and atmospheric corrosion. As acidic substances come in contact with the metals, like iron or steel, rust begins to form. Depending on the environment, corrosion can happen at any rate. It is advisable to take effective precautionary measures for preventing corrosion and this article will suggest the necessary steps.
How to prevent corrosion?
A very effective way to slow corrosion is to apply anti-corrosion protective coating. It protects the substrate by preventing contact between harsh environments and the vulnerable substrate. It is important to find the right anti-corrosion process for the equipment and here are some of the most corrosion protection services.
Cathodic protection is one of the ways to prevent steel corrosion in that it protects the metal’s surface. The process is used to protect a metal structure, mostly iron. An electrically active alloy or metal is deployed near the structure that needs protection. An anode substance is used as a diversion and oxidized until the metal piece completely corrodes. It is also important to use an easily replaceable piece of metal for help.
This type of anti-corrosion process is used in ship hulls and oil rigs. There are 2 methods of protection namely sacrificial anodes and impressed current. In case of sacrificial anodes, a small piece of the galvanic alloy is attached to the structure in the occurrence of sacrificial anodes. Impressed currents use small DC voltage with a grounded anode connected to a rectifier or potentiost at to ensure cathodic protection.
Coating is used for corrosion protection to prevent weathering. Such coating crates a physical barrier between the corrosive environment and the metal surface. The coatings cover the exterior of the metal surface to protect it from external environmental conditions. Paintings and platinum are two common types of coatings. Chrome plating is a good corrosion protection for steel.
Corrosion inhibitors are well accepted in various industries due to their excellent anti-corrosive properties. The mechanism of the method is one of the preferred ways to prevent corrosion and the environmental conditions slow down corrosion. The process is used to protect equipment by covering both, inside and outside of the metal surface.
The inhibitors are formulas that slow down the rate of corrosion of the metal. A thin layer of the protection film is created in such kinds of equipment like storage tanks, engines, and other materials. Such inhibitors can be added without complete dismantling or operation halting.
Choosing the right corrosion prevention method is not easy and each of the methods comes with its pros & cons. Contact the professionals who provide the expert services to prevent corrosion. The professionals will suggest hassle-free methods that best suits the corrosion requirements. One of the simple ways to prevent corrosion is to use a corrosion resistant metal like aluminum or stainless steel in combination with cathodic protection.
