Design Engineering


Definition – Corrosion is a natural process and is a result of the inherent tendency of metals to revert to their more stable compounds, usually through oxides and/or chemical reaction.

Corrosion and Coatings: Component corrosion performance can be greatly improved by the use of corrosion resistant coatings. These specially designed engineered coatings are functional combinations of corrosion inhibitors and other materials, which are designed to extend the corrosion protection beyond the base material ability. Many of these engineered coatings are specifically designed for corrosion control for both galvanic and fretting corrosion applications. This metal corrosion protection can be provided by these engineered coatings at very minimal thicknesses, which aids in both cost and redesign changes.

Types of Corrosion

  • Galvanic Corrosion
  • Atmospheric Corrosion
  • Chemical Corrosion
  • Thermal Corrosion
