Camellia Sinensis were well-known natural product containing phenolic and flavonoid
compounds, which reveals a significant advantage for corrosion inhibition purpose. In
this study, the active compound in Camellia Sinensis were extracted and further
characterized with FTIR to identify the functional group in it including their abundancy.
Corrosion experiment using JR235 mild steel grade was conducted where these
specimens were immersed in the flowing system models in control condition for 60
days. Corrosion performance were investigate using weight-loss method and analysed
using mathematical equation to determine the weight different, thus determining the
corrosion rate. In addition, SEM was used in order to monitor the surface morphology
of mild steel. Results reveal that corrosive layer formation is being inhibited correspond
to extract usage. This research found that the inhibition properties increase with
increasing extract concentration used. Therefore, tea leaves extract serves as an
effective and non-toxic corrosion inhibitor for mild steel in dynamic saline condition.
