Determining Corrosion Efficiency of a Green Solution Prepared from Extract of Dalbergia Sissoo Leaves in H₂SO₄ and its Characterization

Abstract

Corrosion is one of the major reasons why many industrial machines and machine parts deteriorate throughout their lifetime due to corrosion. In this regard, enormous engineers and industry owners are after the remedy for such corrosion to sustain the lifetime of machines and machine parts. There are two obvious ways to think about the solution, one solution is to replace the material for constructing the machines with superior materials and other solution is to find a corrosion resistance technique. Firstly, using the Stainless Steel (SS) for machines is a viable solution to get ride of the corrosion but it will also boost the price of the machines. Thus machine manufacturers are still relying on Mild Steel (MS) to build the machines for different industries. Secondly, a popular solutions to resist corrosion is the synthetic corrosion inhibitors but the concern is the environmental impact of such inhibitors. Finding alternative of synthetic inhibitors is a hot topic of research now-a-days and a trending alternative is green inhibitor. In the search of such inhibitors, a solution of Dalbergia Sissoo extract and H₂SO₄ is used to examine the change of corrosive behavior of Mild Steel Block in the presence of the solution prepared. The result of corrosion efficiency is the prime question in choosing any inhibitors. The method of determining corrosion efficiency of the proposed green inhibitor is discussed in this article. A promising result of maximum 72.44% of corrosion efficiency has been observed in 1M H₂SO₄ solution. The characterization of the corroded mild steel sample blocks are then examined through Fourier-transform Infrared (FT-IR) Spectroscopy Test and Scanning Electron Microscopy (SEM). Result of FT-IR finds the reason of the inhibition whereas SEM reveals the evidence of corrosion inhibition due to the effect of Dalbergia Sissoo.
