Aircraft Corrosion, Theory, Identification, and Treatment
This 16-hour training course provides training that includes theory, causes, and characteristics of corrosion; identification of metals and corrosion products; passivation methods for metal surfaces for corrosion prevention; and the preparation for maintenance coatings. The course addresses corrosion removal by chemical and mechanical techniques, plus a review of nondestructive inspection (NDI) methods.
The electrochemical deterioration of metal used in aircraft construction (commonly known as corrosion) is a continuous problem within the aerospace industry. Also known as metal fatigue, corrosion is a microscopic phenomenon that when left unchecked, can cause millions of dollars in damages and possible tragic results. A simple thumbnail-size corrosion cell can lead to a catastrophic failure in critical components, wings, or fuselages.
The instructor will review case scenarios to provide insight to this natural phenomenon and what aircraft technicians can do to minimize this insidious condition on the aircraft they maintain. Over a 2-day period, interactive teaching and discussion, coupled with photographic examples, will be the foundation to identify corrosion in various types of metal and their alloys and the best practices to protect them to aid in corrosion prevention. The contents and examples from this course go well beyond what is often provided by typical Airframe and Powerplant (A&P) training on this topic.
