Surface morphology study on aluminum alloy after treated with silicate-based corrosion inhibitor from paddy residue

Aluminum alloys have extensive applications in engineering structures like aircraft due to their high strength-to-weight ratio. However, these alloys are very reactive and prone to corrosion attack. Paddy waste is one of the beneficial natural sources that have a potential contribution on inhibiting...
