Q&A with our Corrosion Experts

Fatigue is defined as the damage that occurs in a material due to the repetitive application of loads that may be substantially below its yield point. Most engineering materials contain defects at a...

Refractory metals are a classification of metallic elements that possess properties that make them more durable and resilient than other standard metals. While the definition of this term varies...

Galvanic corrosion is a destructive electrochemical process that occurs when dissimilar metals are in direct or indirect contact with each other with an electrolyte present. During this process, one...

Biofilms are deposits of biological origin that form on surfaces such as the inside walls of pipes, process vessels, storage tanks, condensers and pumps. (Corrosion in process vessels is discussed in...

Corrosion under insulation (CUI), like other forms of corrosion, is electrochemical in nature and therefore is significantly influenced by the temperature of the surrounding environment. The higher...

Microbiologically influenced corrosion (MIC) is a perennial problem for pipelines used to process and transport petroleum products.The challenge for the oil and gas industry is the potential for...

There are several approaches that can be used to identify microbiologically influenced corrosion (MIC) in pipelines.Corrosion monitoring using coupons in a bypass rack is one of the most common...

We need to break this question regarding microbiologically induced corrosion (MIC) into two parts:How do we evaluate the problematic bacterium (including sulfate-reducing bacteria)?How do we...

Microbiologically induced corrosion (MIC) has been identified as a problem in numerous industries where surface water, municipal reclaim water, grey water and even well water is consumed and...

The tool used to measure a polarization current (1 amp = 1 coulomb per second) is called a potentiostat. A potentiostat is an essential device used in corrosion studies to investigate electrochemical...

Firstly, before we answer this question it is important to clear up a common misconception. There is no such thing as a 100% dustless surface preparation method. (For background information on the...

High solids coatings can offer numerous advantages when compared to solvent-based coatings. Some of these advantages include better durability, faster drying times and little to no emission of...

The blast pressure directly determines the velocity of the blast media through the blasting nozzle, and therefore the impact force on the substrate.While there are a wide range of pressures that can...

Plural component protective coatings, as the name suggests, are coatings that are made up of separate elements that are combined prior to application. High solid materials such as polyurethane,...

Wet (vapor) blasting technologies and dry blastingare similar in performance with regards to surface preparation. The shortfalls of older wet blasting technologies have, unfortunately, often been...

A passivator, also known as an anodic inhibitor, is a type of corrosion inhibitor that reduces or blocks reactions at the anode, thus shifting the potential of the metal to a more electropositive...

The white powdery residue produced by zinc rich primers is a corrosion product known as white rust, white corrosion or white storage stain. White rust occurs when a zinc coated surface is exposed to...
