Synthesis, Characterization and Corrosion Inhibition Investigation of substituted triazines on aluminium and mild steel in 1M HCl: Experimental and Theoretical approach
Corrosion is the natural process through which refined metals are gradually converted to more chemically stable forms such as oxides, hydroxides, or sulphides. This process occurs because metals tend to return to their natural states. Proper selection and use of corrosion inhibitors can greatly …

Synthesis of 6-Substitutedchromone-2- Carboxamide derivatives as corrosion inhibitors for metals in acidic medium
Corrosion is the gradual deterioration of a metal's properties as a result of its interaction with the surrounding environment. One method of controlling corrosion is to use corrosion inhibitors, substances added to a corrosive environment in trace quantities to reduce the rate of corrosion. In …

Microcapsule-based self-protecting coatings
Corrosion causes enormous damage to products and infrastructure on an annual basis. The most common approach to mitigate corrosion is to apply a protective coating (layer) to the targeted “substrate” well before placing the item in service. The protective coating acts as a passive layer between the …
