Corrosion Analysis

Solving Corrosion Failures

"It failed by corrosion." This is not a complete failure analysis. How does one solve a corrosion failure? For a corrosion failure to be properly solved it isn't enough to just conclude: "It corroded." Metallurgical Failure Analysis uses a more rigorous method of solving corrosion problems. Using these steps will help to avoid future failures.

  1. Know the forms of corrosion. Metallurgical Failure Analysis has expertise in the many forms of corrosion failures. A typical, poor solution to a corrosion failure is to use a stainless steel alloy to hopefully solve the problem. This may not always work as the corrosion of stainless steels may be accelerated in some common environments.

  2. Identify the specific form of corrosion. Years of experience and the use of sophisticated analytical equipment allows Metallurgical Failure Analysis to identify the form of corrosion failure. A complete failure analysis combined with good engineering judgment is the key to the identification of the form of corrosion. If the form of corrosion failure is not properly identified then the assurance of a good solution is not certain.

  3. Have all the facts about the environment, temperatures and service. An understanding, in depth, of the service environment is a must.

  4. Solve the problem. Metallurgical Failure Analysis will make engineering recommendations for the successful solution of the corrosion failure by: materials selection, process changes or design improvements. Practical, real world recommendations for good solutions have satisfied clients needs. Results are available by clear reports, excellent presentations or verbal methods.

Metallurgical Failure Analysis has expertise in identifying and solving all forms of corrosion failures.
