Abstract

Based on the hexavalent chromium and non-hexavalent chromium system defined by the MIL-DTL-5541 standard, this paper systematically reviews the research progress of chemical conversion coatings for typical aerospace aluminum alloys. It emphasizes the film-forming mechanisms and microstructural characteristics of chemical conversion coatings and analyzes the impact of such coatings on the environmental suitability of aluminum alloys according to the key performance indicators outlined in relevant standards, particularly corrosion resistance and coating adhesion. On this basis, the current shortcomings in the validation of environmental suitability of chemical conversion coatings for aerospace aluminum alloys are summarized, aiming to offer valuable insights for further research.
