Anticorrosion Capacity of Ailanthus altissima (Mill.) Swingle Honey
Tree of heaven (Ailanthus altissima (Mill.) Swingle) is a fast-growing, very aggressive and invasive deciduous tree and the unifloral honey from this plant is rare. Due to its biodegradability, eco- friendliness and low cost, a natural honey fulfils the requirements for a non-toxic green corrosion inhibitor. Several studies confirmed the honey potential application as the corrosion inhibitor of different metals and alloys, but there are no reports on the anticorrosion capacity of this honey type. In the present study the ability of the honey to protect reactive surfaces of Fe and Sn, the main constituent of tinplate, against corrosion in a saline solution, pH 3.0, was tested using dc electrochemical methods and electrochemical impedance spectroscopy (EIS). The nondestructive EIS method was used at the open- circuit potential (EOCP) under static conditions. EIS parameters obtained in situ in a wide frequency range were correlated to the phenomena that occur simultaneously at different time scales: the charge- transfer resistance, capacitance and resistance of the surface film, and the resistance to the transport of metal species through the film. From dc and ac measurements the corrosion kinetic parameters were derived. Results show that Ailanthus altissima (Mill.) Swingle honey in investigated concentration range inhibits corrosion of Sn while the inhibitory activity on Fe was not established.
