This research paper is about Dendrobium Crumenatum (pigeon orchid) as green
inhibitor to protect the mild steel coupon from the corrosive effect since it’s abundantly
available in Malaysia and reasonably low-cost. The elements contain in the stem of
the Dendrobium Crumenatum which are saponin, phenolic, alkaloid, tannin and
flavonoid being the main properties for Dendrobium Crumenatum to act as green
corrosion inhibitor. The extract of the Dendrobium Crumenatum blend with the Bluel,
high quality fast drying alkyd paint will be coated to the mild steel by using dip
coating method. The properties of the Dendrobium Crumenatum will be investigated
through EIS, FTIR and SEM. The coated mild steel being studied in different seawater
velocity as to investigate the fluid velocity as disturbance factor to the corrosion
inhibition process. This experiment will be investigated through weight loss method.
