Corrosion testing

What is corrosion?Corrosion Testing

Corrosion is referred to as the deterioration of a material through chemical interaction with the surrounding environment. Corrosion caused by fuels and lubricants can result from a number of parameters which include undesirable sulphur compounds, moisture, dissolved salts and temperature.

Left unchecked, corrosion can cause irreversible damage to engines, pipelines and other assets. Such problems are not only costly to rectify but can lead to equipment failure as well as health and safety risks.

As an example, corrosion damage to the fuel system of aero engines has in the past been clearly attributed to the presence in some Aviation Turbine Fuels (ATF’s) of undesirable sulphur compounds.

Most fuel and lubricant specifications include test methods for corrosion.

Corrosion testing is fundamental in assessing how fuels and lubricants perform under simulated service conditions and helps to support effective control and prevention of problems caused by corrosion. Laboratory tests assist to:

  • Determine whether a fuel sample has been contaminated with potentially corrosive agents such as hydrogen sulphide, mercaptans, elemental sulphur or inorganic acids
  • Rate the effectiveness of copper and silver corrosion inhibitors in preventing corrosion
  • Identify those fuel blend components that may lead to the corrosion of alloys such as brass, bronze and silver, these alloys being often found in fuel system components
