Ma keʻano laulā, hiki ke hoʻokaʻawale ʻia nā ʻano hana pale corrosion i ʻelua mau ʻāpana nui:
1. ʻO ke koho pololei ʻana i nā mea e pale ai i ka corrosion a me nā hana pale ʻē aʻe
2. Ke koho ʻana i nā kaʻina hana kūpono a me nā hale hana.
ʻO ka mālama pono ʻana i nā loina kaʻina hana i ka hana kemika hiki ke hoʻopau i nā hanana corrosion pono ʻole. Eia nō naʻe, ʻoiai inā hoʻohana ʻia nā mea kūʻē i ka corrosion kiʻekiʻe, hiki i nā kaʻina hana kūpono ʻole ke alakaʻi i ka ʻino nui.
1. Nā mea pale ʻino ʻole,
ʻO ka maʻamau, hiki i ka hoʻohui ʻana i kahi liʻiliʻi o nā mea hoʻopaneʻe corrosion i kahi kaiapuni corrosive hiki ke hoʻolōʻihi i ka ʻino metala. Hoʻokaʻawale ʻia kēia mau mea paʻa i ʻekolu ʻano: inorganic, organic, a me vapor-phase inhibitors, kēlā me kēia me nā mīkini ʻokoʻa.
• Anodic Inhibitors (hoʻolohi i ke kaʻina hana anodic):
Hoʻopili kēia i nā mea oxidizer (chromates, nitrites, iron iron, etc.) e hoʻoikaika ana i ka passivation anodic a i ʻole nā mea kiʻi kiʻi anodic (alkalis, phosphates, silicates, benzoates, etc.) Hoʻopili mua lākou i ka ʻāina anodic, hoʻonui i ka polarization anodic. ʻO ka mea maʻamau, hana nā mea hoʻopale anodic i kahi kiʻiʻoniʻoni pale ma ka ʻili anode, ʻoi aku ka maikaʻi akā loaʻa kekahi pilikia - ʻaʻole lawa ka nui o ke ʻano i hiki ke hopena i ka uhi kiʻiʻoniʻoni piha ʻole, e waiho ana i nā wahi metala liʻiliʻi i ʻike ʻole ʻia me ke kiʻekiʻe o ke au anodic kiʻekiʻe.
• Nā Kāohi Cathodic (hana ma ka hopena cathodic):
ʻO nā laʻana e like me ka calcium, zinc, magnesium, copper, a me nā ion manganese, e hoʻopili me nā ion hydroxide i hana ʻia ma ka cathode e hana i nā hydroxides insoluble. Hoʻokumu kēia i nā kiʻiʻoniʻoni mānoanoa ma ka ʻili cathode, e ālai ana i ka hoʻoheheʻe ʻana o ka oxygen a me ka hoʻonui ʻana i ka polarization.
• Nā mea ho'ōki i hui pū ʻia (hoʻopaʻa i nā hopena anodic a me ka cathodic):
Pono kēia mau mea i ka hoʻoholo hoʻokolohua o ka dosage kūpono.

2. ʻO nā mea hoʻomāinoino kino
Ke hana nei nā mea hoʻokoloʻi organik ma o ka adsorption, e hana ana i kahi kiʻiʻoniʻoni ʻike ʻole ʻia, molecular-mānoanoa ma ka ʻili metala i ka manawa like e hoʻopau i nā hopena anodic a me ka cathodic (ʻoiai me nā ʻano like ʻole). ʻO nā mea hoʻopaneʻe organik maʻamau, ʻo ia nā pūhui nitrogen-, sulfur-, oxygen-, a me ka phosphorus. ʻO kā lākou mau hana adsorption e pili ana i ka molecular structure a hiki ke hoʻokaʻawale ʻia e like me:
· Electrostatic adsorption
· Kemimi adsorption
· π-bond (delocalized electron) adsorption
Hoʻohana nui ʻia nā mea hoʻokae organik a ulu wikiwiki, akā loaʻa iā lākou nā drawbacks, e like me:
· ʻO ka hoʻohaumia ʻana o ka huahana (ʻoi loa i nā noi pili i ka meaʻai) - ʻoiai e pōmaikaʻi ana i hoʻokahi pro
ka pae hoʻoiho, hiki ke lilo i mea pōʻino i kekahi.
· Kaohi ʻana i nā hopena i makemake ʻia (e laʻa, hoʻolohi i ka wehe ʻana i ke kiʻiʻoniʻoni i ka wā o ka pickling acid).

3. Nā mea hoʻopaʻapaʻa ʻino-Phase,
He mau mea hoʻoheheʻe loa kēia i loaʻa nā pūʻulu hana corrosion-inhibiting, i hoʻohana mua ʻia e pale i nā ʻāpana metala i ka wā o ka mālama ʻana a me ka lawe ʻana (pinepine i ke ʻano paʻa). Hoʻokuʻu ko lākou mau mahu i nā pūʻulu hoʻopaʻapaʻa ikaika i ka makū o ka lewa, a laila hoʻopili i ka ʻili metala e hoʻolōʻihi i ka ʻino.
Hoʻohui ʻia, he mau adsorptive inhibitors lākou, ʻo ia hoʻi, ʻaʻole pono ka ʻili metala i pale ʻia i ka wehe ʻana ma mua.
