ʻO ka corrosione he phenomenon i kahi o kahi mea e hana ai i kahi mea e pono ai a iʻole ka hopena electrochemical a me nā mea e pili ana i nā mea e pili ana. Inā i loko o kā mākou ola i kēlā me kēia lā, a iʻole ma ka hanaʻoihana, metal "Rust" eʻikeʻia i nā wahi nui, nā mea kanu manu, nā mea kanu manu, nā mea kanu a me nā alaloa. ʻAʻole e loaʻa wale nō ka corrosion i nā poho waiwai, a alakaʻiʻia i nā pilikia palekana
I ka palena palena palena o ka substrate, e hoʻonuiʻia ka mea hana mua mua. Ma muli o ka heleʻana o ka oxygen i ka lewa, e noho ana keʻano o ka hopena ma keʻano o kahi oxide aʻo ia hoʻi he prik mua loa. ʻO ka papale ka mea nui loa a me ka mea mua e pale i nā corrosione hou aʻe.
Ma luna o ka papa kuhikuhi o ka heluʻana, nā mea i hōʻiliʻili i nā mea i hoʻohuiʻia i nā papa hana adsorbed. ʻO ka mea maʻamau ka wai mua,ʻo ia, ma muli o keʻano amphteric o nā mode metala o ka nui, e hoʻopiliʻia ai nā mea hou aku. ʻO kēia'āpana kahi mea e pono ai keʻano o ka mokuahi,ʻo ia ka mea ikaika a paʻakikī i ka hoʻokaʻawaleʻana. Hoʻopiliʻia ka papa hana o ke Kemika e ka papa inoa o ka adsorption kino,ʻo ia ka mea i loaʻa i ka blecular maikaʻi a ke hoʻololi maʻalahi.
ʻO ka kiʻiʻoniʻoniʻo Oxideʻo ia ka mea nui loa o ka paleʻana o ka corrosione Ma nā hua'ōlelo'ē aʻe, e hoʻomaka ka pale o ka corrosionion i ka wā o ka hoʻokumuʻana a me ke kūpaʻaʻana o ka kiʻiʻoniʻoniʻo Oxide Mobile (Pof). Ke hilinaʻi nei i nā mea kilokilo, hoʻohuihui (eg i nā mea he nui, remox adit). Hoʻomaka pinepineʻiaʻo Corrosionion me ka decomposition o ka kiʻiʻoniʻoniʻo Oxide,ʻo ia ka mea e kū pono ana i nā mea kilokilo o ka alling
ʻO keʻano maʻamau o ke ola i ke ola heʻano likeʻole o nāʻanoʻano likeʻole, e nānā i nāʻano likeʻole o nāʻano heʻehiku.
1. Erosion Corrosion:Hoʻokomoʻia ka metala i ka erosion kokoke i keʻano o kaʻili. ʻO ia kaʻano maʻamau maʻamau o ka corrosio a ua hana pinepineʻia e ka wai a iʻole ka ea lepo.
2. Crevice Corrosioni:Hiki i nā mea hana ma waena o nā metala a iʻole nā lālā i hiki ke alakaʻi i ka corrosio no ka mea e paʻa ai ka electrolyte e ka hana capillary a hiki ke hana i nāʻokoʻa nui. Hiki i kēia ke pale i ka hoʻolālāʻana i nā hana koho.
3ʻO ka corrosile electrOchemical e hopena maiʻelua mau metalaʻelua e hoʻopili pū me kekahi me kekahi i ka manawa like, me kekahi o nā mea pili i ka nui. Hiki ke paleʻia ma ke kohoʻana i nā mea kūpono a iʻole e hoʻopili ai i keʻano o keʻano ma waena o nā lako.
4.Nā hua kiʻi nui i ka hoʻopiliʻana, e kāʻei ana a iʻole ka piko. ʻO ia ka mea i hanaʻia e ka pohō i ka pōʻino i ka pale pale, e like me nā pona i loko o ka coating a iʻole chloride erosion ma keʻano he nui.
5.ʻO ka pahu or orr norrite crris a me crni austetitic ma loko o nā palena palaoa, e hoʻokaʻawale i ka paʻa o nā hua ma waena o nā pale i waena o nā pale. Hiki i ka corrosition interterar i hiki ke hana i ka ikaika o ka ikaika a me ka distislity, crcumbling ma lalo o ka ukana maʻamau
6.ʻO ka corrosiot dew-point corrosion:E pili ana i ka corrosition dew-point i ka steam saturated ma muli o ka hōʻoluʻolu a me ka hoʻoponoponoʻana i nā mea kanu, a me nā kinikini croil.
