Surface Treatment in Aerospace Industry: A Study on Acid Pickling and Paint Adhesion

Abstract

This paper provides an overview of the essential elements in the design and production of aviation components, namely surface treatment, acid pickling, paint adhesion, and Failure Modes and Effects Analysis (FMEA). These factors are critical in ensuring the dependability and safety of aircraft components. Surface treatment is necessary to ensure that paint and coatings adhere to the substrate, while acid pickling is used to treat surfaces and remove impurities, increasing surface roughness. The paper discusses the factors that affect paint adhesion and the procedures used to assess it. FMEA is a systematic approach used in the aerospace industry to identify potential failure modes and evaluate their severity, probability, detectability, and countermeasures. The authors highlight the importance of each of these criteria and emphasize that significant attention must be given to ensure the reliability and safety of aviation components. Careful regulation of acid application is necessary to prevent surface deterioration. Proper preparation of the surface, coating technique, and application circumstances significantly influence paint adhesion. In summary, the aircraft industry places significant emphasis on dependability and quality, and these essential elements must be considered in the design and production of aviation components.
