Abstract
Corrosion problems in industrial sectors, it is necessary to use corrosion inhibitors, most of the compounds used in the manufacture of inhibitors are very toxic. The use of green corrosion inhibitors has been studied with great intensity for the development of sustainable economies that promote the care of the environment through ecological alternatives and of low cost. Plant extracts are biodegradable and represent a renewable source of chemical compounds. In this work the coffee husk was used as a corrosion inhibitor, the material studied was a stainless steel AISI 440 in 1M H2SO4 medium. EIS tests were performed to compare the inhibitory effect. The results showed that in fact, the addition of coffee extract in the solutions rich in sulfuric acid was able to inhibit pitting and localized corrosion in stainless steel.
