Conductive, Anti-Corrosion, Self-Healing Smart Coating Technology Incorporating Graphene-Based Nanocomposite Matrix

Chromate conversion coatings have been in service for decades providing robust corrosion protection to a wide variety of aluminum alloys. However, it is also known that anti-corrosive containing Cr 6+ contributes DNA damage, cause cancer and are not environmentally friendly. Consequently, regulatory restrictions over the use were established mitigate environmental damage health problems. To answer this hurdle meet emergent need friendly coatings, we successfully developed an innovative coating combines anti-corrosive, low electrical resistance, self-healing properties. First, present two different aim display resistance properties: one only graphene other Zn nanoparticles graphene. Confocal laser imaging SEM microscopy was used observe morphology coatings. The measured using 4-wire connection Kelvin method. We compare anticorrosive response both under neutral salt spray test (NSSt). Raman spectroscopy performed before after understand effect NSSt corrosive species on Then, select with lower program mechanism boost its life service. Finally cyclic voltammetry confirm excellent blocking properties tested All presented work applied AA 2024T351 optimal parameters nanofillers dispersion obtained. Our findings show great potential preventing compatibility fully automated large-scale applications fields such as aerospace, automotive, construction, submarines many more.
