Abstract Scope |
In recent years, protection against corrosion, high temperature, and other extreme environmental service conditions is provided by applying different coatings to metal substrates. These materials mainly find applications in aerospace, automobile and commercial industries. Coatings mainly differ depending on the type of application, substrate, deposition technique, and properties desired. It is necessary to remove these coatings during inspection, refurbishment of damaged coating, and remanufacturing of end-of-life materials. Some removal techniques commonly applied are chemical stripping, high-pressure water jet technique, and impacting abrasive media. While selecting a suitable removal technique, it is essential to consider environmental, economic, and safety hazards. This review gives an in-depth review into the existing coating removal techniques and the various factors that must be considered while choosing a removal technique, and provides case studies of currently in-use coated materials. |
