“…Due to its reducing properties, tannins can also reduce Fe2O3 to Fe^(3+) ions. Ferro-tannate can undergo direct reduction upon contact with O2 and H2O, resulting in ferri-tannate [19]. The addition of corrosion inhibitors has proven to be an efficient approach in effectively controlling corrosion.…”

The release of ions is the initial stage of the corrosion process in an orthodontic wire. Continuous release of ions can reduce the effectiveness and performance of the orthodontic wire. Continuous release of ions in CuNiTi orthodontic wire can change the properties of the wire and trigger hypersensitivity reactions, also in stainless steel orthodontic wire which experiences continuous release of ions can reduce its stiffness. The tannin in avocado seeds is useful as a corrosion inhibitor it can inhibit the release of ions because they are able to bind with metal ions and form a passive layer also able to bind with Fe ions in stainless steel orthodontic wires to form a passive surface layer which is able to inhibit the release of ions when the corrosion process occurs. The aim of this research is to determine the effect of avocado seed extract as a corrosion inhibitor on the release of metal ions from CuNiTi and stainless steel orthodontic wires. Rectangular CuNiTi and stainless steel orthodontic wires measuring 0.017 x 0.025 inches were taken in 3 groups (1 control group soaked in artificial saliva and 2 treatment groups soaked in avocado seed extract). The samples were soaked in avocado seed extract with a concentration of 1.5 g/L and 2 g/L for 7 days. To see the release of ions, an X-Ray Fluorescence test is carried out. In CuNiTi orthodontic wire from the one way ANOVA test showed that there was a significant difference between the control group and all treatment groups on Cu, Ni and Ti ions. The Post Hoc LSD test showed that there were significant differences between the control group, treatment group 1 and treatment group 2 in Cu, Ni and Ti ions with a p value. In stainless steel orthodontic wire, the one way ANOVA test showed that there was a significant difference between the control group and all treatment groups in Fe and Ni ions but not significant in Cr ions in the ion release test with a p value <0.05. The Post Hoc LSD test showed that there were significant differences between the control group, treatment group 1 and treatment group 2 in Fe and Ni ions with a p value <0.05. Providing avocado seed extract with tannin content at concentrations of 1.5 g/L and 2 g/L can inhibit the rate of ion release in CuNiTi and stainless steel orthodontic wires due to the corrosion process.

The investigation about determining the efficiency of inhibition of johar flower ethanol extract in the corrosion reaction of A36 steel (ASTM)/SS400 (JIS) in 3% NaCl solution has been done. This research aims to determine the immersion time and concentration of johar flower ethanol extract in inhibiting the rate of corrosion on steel plates with the highest value of inhibition efficiency. Making the inhibitor is done by extracting the johar flowers using the maceration method. The extract was mixed into the 3% NaCl corroding media with variations in concentrations of 0, 1000; 2000; 3000 and 4000 ppm, then immersed steel plate samples with a size of 50 × 20 × 3 mm for the variation of immersion time 5; 10; 15 and 20 days. Corrosion testing is carried out using the weight loss method. The test results showed that secondary metabolite compounds in johar flower ethanol extract could function as a corrosion inhibitor by inhibiting the rate of corrosion on the steel plate. The inhibition efficiency for johar flower ethanol extract was found in the concentration of 3000 ppm with immersion time for 15 days, amounting to 33.49%.
