Overview

Corrosion is defined as the deterioration of a material, usually a metal, because of a reaction with its environment and which requires the presence of an anode, a cathode, an electrolyte, and an electrical current. The annual cost of corrosion and corrosion protection in the U.S. is estimated to be in the billions of dollars. Corrosion can be mitigated by five basic methods: coatings, cathodic protection, materials selection, chemical inhibitors, and environmental change. It is important that the engineer understands the causes and forms of corrosion, as well as the available protections, to ensure that the most cost effective corrosion mitigation method is employed for each application.

In this course, the student will study the causes and forms of corrosion and the methods available for providing corrosion protection. The course will cover Chapter 2, "Corrosion Theory and Protection" in the US Army Corps of Engineers document EM 1110-2-3400, "Painting: New Construction and Maintenance".

The student must take a multiple-choice quiz consisting of ten questions at the end of this course to obtain PDH credits.

Specific Knowledge or Skill Attained

This course teaches the following specific knowledge and skills:

  · Causes of corrosion
  · The galvanic series in seawater
  · Forms of corrosion, including galvanic, concentration-cell, pitting, intergranular, stress corrosion, dealloying, and erosion corrosion
  · Corrosion mitigation methods, including design practices, sacrificial anode systems, impressed current systems, corrosion inhibitors, and protective coatings

State Board Acceptance

This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states that mandate continuing education for engineers, it is the individual engineer's responsibility to determine the suitability of activities for PDH credit. The state boards typically accept online* courses that cover technical, managerial** or ethical content and which are relevant to the practice of engineering. The course must have a clear purpose or objective with a content that will maintain, improve or expand the skills and knowledge of the licensee's field of practice. For questions about your mandatory PDH requirements, visit the website of your state licensing board.

*Online courses are accepted by all state licensing boards that mandate continuing education. Other than New York (which limits online courses to 18 PDH) and Iowa (which limits online courses to 6 PDH), there are no limits placed by other states on the number of hours that can be earned through online continuing education. Consult with your state licensing board if you have any questions about the acceptability of online courses.

**The New York State Board of Engineers does not accept general office management courses, but will accept project management courses that are offered by an approved provider and that are technical in nature and contribute to the engineer's professional practice.

Please Note: Continuing Education credits for this course are awarded as PDH (Professional Development Hour Credits).
