“…Synthetic compounds containing multiple bonds and heteroatoms are effective inhibitors, but at the same time the processing time, cost, and their toxic nature have compelled researchers to look for alternatives [6]. The inhibiting effect of some of these synthetic organic compounds on the corrosion of mild steel has been recently reported by several authors [1,5,10,[12][13][14][15][16][17][18][19][20]. However, most of the compounds that constitute these inhibitors are expensive and toxic to human and the environment.…”

Traditionally, reduction of corrosion has been managed by various methods including cathodic protection, process control, reduction of the metal impurity content, and application of surface treatment techniques, as well as incorporation of suitable alloys. However, the use of corrosion inhibitors has proven to be the easiest and cheapest method for corrosion protection and prevention in acidic media. These inhibitors slow down the corrosion rate and thus prevent monetary losses due to metallic corrosion on industrial vessels, equipment, or surfaces. Inorganic and organic inhibitors are toxic and costly and thus recent focus has been turned to develop environmentally benign methods for corrosion retardation. Many researchers have recently focused on corrosion prevention methods using green inhibitors for mild steel in acidic solutions to mimic industrial processes. This paper provides an overview of types of corrosion, corrosion process, and mainly recent work done on the application of natural plant extracts as corrosion inhibitors for mild steel.

“…effected both anodic and cathodic sites in tafel plot with E corr value towards more noble values and it suggest that inhibitor behaved as mixed-type inhibitor [15]. Table 4 shows that corrosion rate (CR) decreases when the values of current density (I corr ) become smaller due to the lower temperature and presence of henna extract.…”

Abstract. The investigation of coating incorporated with various percentages of henna has been conducted by means of weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy method. Mild steel has been studied at ambient temperature and 50°C in order to examine the effect of temperature. The potentiodynamic polarization measurements indicate that henna extract acts as a mixed inhibitor while the corrosion rate (CR) value decreases as the current density (I corr ) decreases in the presence of 10% henna extract for both temperatures. Surface and protective film analysis have been carried out using Fourier transform infrared (FTIR) and scanning electron microscopy (SEM).The inhibition activity is mainly correlated with the major active functional groups of lawsone. The main components can be found in lawsone structures are phenols O-H, carboxylic acid C=O and alkenes C=C. The morphology of the uninhibited sample showsa rough surface of mild steel as a result of corrosion process and severe damage can be seen. In the presence of henna, a smooth surface of mild steel anda uniform deposition of henna were observed.

“…Polymers are magnificent consumption inhibitors for metallic antiques in corrosive condition. Nearness of a little amount of polymers might be powerful in hindering the consumption of metals in fluid acidic condition (22)(23)(24)(25)(26). Time is a champion factor while describing the corrosion inhibitor.…”

As corrosion inhibitors for mild steel in acidic media, polymers are emerging materials due to its larger surface coverage area. This paper focuses on the characteristic of water-soluble solvent polyvinyl alcohol (PVA) at interface of mild steel under 0.5 M HCl, examined using electrochemical impedance spectroscopy, Tafel polarization, and weight reduction techniques. The findings of the study revealed that water-soluble polyvinyl alcohol as polymer inhibitor has restraint abilities, up to 93.7 percent for 3 hours in 0.5 M hydrochloric acid. An advanced form of high spatial resolution imaging of surface of mild steel at different stages was found by using scanning electron microscopy which shows that the sample immersed for 3 hrs in 0.5 M HCl with 100 ppm of water soulble PVA inhibitor provides good inhibition quality to corrosion on mild steel surface.
