Novel polymeric inhibitor for corrosion of 57S aluminium in 2M NaOH solutions

Abstract

Purpose

The purpose of this paper is to show how to develop inhibition 57S aluminium in 2M NaOH solution.

Design/methodology/approach

The approach is used to measure gravimetric and polarization measurements.

Findings

The results of the paper clearly reveal that the 0.2 M ZnO with 700 ppm polyaniline in N‐methyl‐2‐pyrrolidone solution is found to offer inhibition up to 71.2 per cent.

Originality/value

The paper deals with the development of newer inhibitor based on polyaniline. Gravimetric and galvanostatic methods were employed to evaluate inhibition efficiency.
