The tests successfully demonstrated the ability of Zentek’s ZenARMOR™ nano-pigments to inhibit corrosion in aluminium alloy AA2024-T3.
Zentek is pleased to announce the successful completion of its Innovative Solutions Canada (ISC) – Testing Stream contract for ZenARMOR™, a cutting-edge nano-pigment technology designed for military-grade, chromate-free corrosion protection in aerospace paints.
The ISC contract focused on evaluating the performance of ZenARMOR™ nano-pigments in preventing corrosion of aluminium alloy AA2024-T3. The testing programme, conducted by the Aerospace Research Centre’s Aerospace Manufacturing Technologies Centre at the National Research Council of Canada (NRC), involved the application of ZenARMOR™-enhanced coatings to aluminium coupons.
Three batches of AA2024-T3 test coupons, both scribed and non-scribed, were coated with standard paints and paints enhanced with ZenARMOR™. Corrosion resistance was assessed using ASTM B117 and ASTM D5894 protocols. The final test round used the ASTM D5894 cyclic corrosion method, which better replicates real-world exposure.
After 2,016 hours of accelerated corrosion testing, no visible substrate corrosion or coating failures were detected on any of the ZenARMOR™-treated samples. These promising results confirmed the nano-pigment's effectiveness. However, due to comparable performance from control samples, the NRC team has recommended further evaluation in other coating systems or where ZenARMOR™ is the sole corrosion-inhibiting agent, to fully gauge its independent contribution.
