Anodized aluminum, due to its inherent porous channels and thin protective layer, exhibits poor corrosion resistance friction performance in severe environments. In this study, an in-situ growth of a NiZnAl-LDH composite coating was developed on the surface aluminum. Sodium molybdate ricinoleic acid were used modify coating, enhancing both performance. Various tests, including SEM, infrared, XPS, XRD, others, conducted analyze structure, composition, properties synthesized coating. The results confirmed successful synthesis with nitrate intercalation, which subsequently converted intercalation through sodium modification. Electrochemical tests revealed that current decreased by factor two compared plain LDH Friction experiments demonstrated co-modified exhibited minimal coefficient 0.23, outperforming original

Aluminum alloys are extensively used to manufacture mechanical components. However, when exposed alkaline environments, like lubricants, refrigerants, or detergents, they can be corroded, reducing their durability. For this reason, the aim of study is investigate influence aggressive solutions (i.e., pH and presence chlorides) on corrosion resistance three aluminum (AA 5083-H111, AA 6082-T6, 7075-T6) with without anodizing treatments. Open circuit potential (EOCP) anodic polarization measurements were carried out typical parameters such as current density (icor) rate (CR) determined. Morphology attack samples microstructure investigated by scanning electron microscope. Results show that behavior influenced (i) aggressiveness testing environments; (ii) thickness treatment; (iii) alloy chemical composition; (iv) distribution intermetallic phases in matrix. Moreover, galvanic series have been built also other metallic commonly applications, i.e., carbon steel (C40), stainless-steel (AISI 304), Cu-based (Cu-Ni CW 617 N, respectively). clearly indicate play a fundamental role it necessary select an for specific environment, highlighting thermodynamic conditions occurrence. On hand, kinetic microstructural studies stress importance surface treatments relevant well effect metal exposure. Future work will involve evaluation acidic environments.
