Henna is identified as an excellent corrosion inhibitor and due to this reason, a research project was conducted in order to investigate the ability of henna extracts to act as an anticorrosive agent with the compatible composition for paint systems. The paint composition consisted of colophony (WW types), plasticiser (oleic acid), pigment (calcium carbonate), solvent (mixture of xylene/white spirit) and additives (zinc oxide and henna leaf extract). These ingredients were mixed until they were soluble and stirred using a high-speed disperser. In order to measure the effectiveness of the new paint system, several nondestructive tests were conducted to investigate the inhibitive properties of henna extract including measurement of substrate mass loss. The inhibition efficiency (IE) increased with the increasing amounts of inhibitor. The highest IE (%) was 77.63% and this was produced by the paint with 8% inhibitor (P3). However, the IE value started to decrease when 12% of henna extract was incorporated into the paint matrix (P4: 58.40%). Thus, P3 acted as an optimum paint with respect to its performance on the corrosion inhibition efficiency based on mass loss measurement and electrochemical studies. Surface analyses were carried out using infrared thermography and scanning electron microscopy. These surface analysis test was carried out to support mass loss and electrochemical study. Based on the results, the performance of henna extract as a corrosion inhibitor on aluminium surface showed a great impact with the 8% of henna extract presence in the paint formulation.

Metallic materials are the most applicable materials in various industries. They are useful due to their excellent mechanical properties. However, they are exposed to corrosion because the environment contains oxygen, humidity and some other factors. This paper describes about a paint incorporated with organic inhibitor, i.e., henna extract. This paint was produced to enhance its anticorrosive property. Henna extract was chosen as the corrosion inhibitor as it is organic, environmentally acceptable, readily available and a renewable source of material for a wide range of corrosion problems. The extractions were characterised by using Fourier Transform Infrared. Meanwhile, the inhibitive action of henna extract was investigated through an electrochemical technique. The inhibitive effects of henna extract were investigated with percentages of 0%, 4%, 8% and 10% incorporated into a rosin (epoxy)-based matrix. The specimens were characterised by electrochemical impedance spectroscopy measurement. The morphology study was investigated through surface analysis by using scanning electron microscopy. The inhibition efficiency increased as the concentration of henna extract was increased. The results showed that Paint 3 has the lowest corrosion rate of 0.001767 mm/yr as compared to Paint 1 with 0.005148 mm/yr. The inhibitive action of the henna extract is discussed. Paint 3 was proposed as the most effective paint that contains a natural inhibitor for aluminium alloy.

“…In this case, the use of bee wax propolis (BWP) as inhibitors has shown to inhibit the corrosion rate on 304SS in H2SO4 solution. In the inhibition of corrosion rate mixed type of polarization occurs [11].

“…Inhibition efficiency (IE %) decreased as the temperature increased. The mechanism of inhibition of extract BWP on the 304SS was physisorption, following Temkin isothermal equation [11]. Linear polarization studies have been conducted to estimate the corrosion rate or to analyze the passivation of metals, corrosion protection using inhibitors, sacrificial barrier properties, and coating on metal [12][13][14].…”

Corrosion in the reservoir and transport vessel often causes a leak that leads to disaster. Data prediction and experimental corrosion in storage technology is very important to prevent damage and reduce maintenance costs. Theoretically, steel tank corrosion by sulfuric acid working medium can be minimized with the formation of sediments oxide by oxidation-reduction reaction. Behavioral inhibition of bee wax propolis on the 304SS in 0.5 M sulfuric acid was carried by potentiodynamic polarization. Based on the polarization testing the corrosion rate of the 304SS in a solution of 0.5 M H2SO4 is at 0.349 g/m 2 d with the missing mass amounted 5.21 x10 -9 g/s. In experiments, the inhibitor causing less mass loss is equal to 2.28 x 10 -11 g/s. Mass lost without and with inhibitor in this study is also known by theoretical calculations. The mass losses can be used to determine the inhibition efficiency. The calculation of the efficiency theoretically and experimentally gives the same result.
