摘要
The blister test was used to assess the effect of various pretreatments, including chromate conversion coatings, non-chromium process conversion coatings, and trivalent chromium process coatings, on the adhesion strength of acetoacetate coatings to aluminum alloy (AA) 2024-T3 (UNS A92024). The effects of cleaning and desmutting prior to conversion coating and improper water rinse temperature after cleaning were also addressed. The results revealed that when properly applied, pretreatments improved the adhesion strength of acetoacetate primer on AA2024-T3. In addition, cleaning and desmutting improved adhesion for all conversion coatings, except for chromate conversion coatings, and the level of adhesion depends on the particular conversion coating used. Process control was found to be of great significance for the performance of acetoacetate coating systems applied on AA2024-T3, as a low rinse water temperature after cleaning resulted in coating blistering.
