ʻOku fakafotunga ʻe he ngaahi maama ʻo e fakamoʻoni ʻa e loto vilitaki ki he vai, efu, mo corrosion. Ko hono fakaʻaongaʻi ʻo e ngaahi naunau pau ʻo e oxidation mo e kau ʻAnitai-corrosion fakataha mo e ngaahi meʻa fakamaʻu, ʻoku nau fakahoko stringent tuʻunga maluʻi. ʻOku fakanaunau ʻa e ngaahi maama ko ʻeni ʻaki ʻa e corrosion-matuʻuaki, ʻikai ke ʻi ai ha vai, mo e ngaahi papa ʻoku ne puleʻi e oxidation. ʻOku fakaʻaongaʻi ʻa e circuits ʻoku puleʻi ʻe he ʻea ke fakasiʻisiʻi ʻa e malohi ʻo e ʻea, ʻi hono fakamavaheʻi ʻe he ngaahi meʻa fakaʻuhila mo e insulated connectors, guaranteeing e angatonu mo e falalaʻanga.

Predominantly palangi ʻi he ngaahi feituʻu lalahi ʻoku fakahehema ke corrosion, efu, mo e ne tafea — hangē ko e ʻakau mālohí, ngaue ʻa e kau ngaue, ngaahi feituʻu petrochemical, vaka, mo e ngaahi fale tauʻanga meʻalele — ʻoku fakataumuʻa ʻa e ngaahi maama fakamoʻoniʻi ʻo e Tulai ke katakiʻi ʻa e ngaahi tuʻunga faingataʻa, ʻo fakalōloaʻi ai ʻenau moʻui tokoní.
ʻOku ʻi heʻenau taumuʻa ʻa e sipinga divergence: ʻOku fakatapui ʻa e ngaahi maama ʻo e fakamoʻoni ki he malu ʻo e ʻatakai, ka ʻoku tukupa ʻa e ngaahi maama fakamoʻoniʻi ʻo e Tulai ke fakatolonga ʻenau ngaue informant. TATAKI e ngaahi mama, ʻi he taimi ʻoku fakamoʻulaloaʻi ai ki he dustproofing, waterproofing, mo e fakaʻauha-proofing (fakafepaki ki he corrosion) ngaahi faitoʻo, ʻe lava ke ngaue lelei ko ha ngaahi founga ke fakaleleiʻi ʻaki e mama.
