I ka wā o ka hoʻohana ʻana, pili nā ʻāpana kila i ka corrosion electrochemical a me ka corrosion kemika ma muli o ka mana o ke kaiapuni hana. He mea maʻamau i nā noi ʻoihana e hoʻomaikaʻi i nā waiwai o ka ʻili o nā mea hana ma o ka ʻenehana lapaʻau ʻili a hoʻonui i nā waiwai anti-corrosion o nā mea hana. Hoʻopuka kēia pukana i ʻelua ʻenehana ʻili me nā waiwai anti-corrosion maikaʻi loa: ʻenehana lapaʻau ʻili Dacromet

ʻO ka ʻenehana lapaʻau ʻāina ʻo Dacromet kahi ʻenehana anti-corrosion coating, i hoʻohana nui ʻia no ka pale ʻana o nā huahana metala. Hoʻohana ʻo ia i ke ʻano hoʻoheheʻe electroless e uhi pono i ka ʻili metala me kahi ʻāpana o ka uhi inorganic me nā waiwai anti-corrosion. ʻO ka mahana hana maʻamau ma kahi o 300°C. Hoʻokumu nui ʻia kēia uhi me ka zinc flaky ultrafine, aluminika a me chromium, hiki ke hoʻomaikaʻi maikaʻi i ka pale ʻana o nā huahana metala a hoʻolōʻihi i ko lākou ola lawelawe. Hiki i ke kaʻina hana Dacromet ke hana i kahi papa kiʻiʻoniʻoni o 4 ~ 8 μm ma ka ʻili o ka mea hana. Ma muli o nā ʻāpana o ka flake zinc a me ka alumini, pale ia i ka media corrosive e like me ka wai a me ka oxygen mai ka hoʻopili ʻana i nā ʻāpana kila. I ka manawa like, i ka wā o ka hana ʻana o Dacromet, hoʻopili kemika chromic acid me ka zinc, ka pauka alumini a me ka metala kumu e hana ai i kahi kiʻiʻoniʻoni passivation paʻa, nona ka pale corrosion maikaʻi.

ʻO ka maʻamau, ʻo ka ʻenehana lapaʻau ʻili o Dacromet kahi ʻano hana lapaʻau maʻamau. Hoʻohana nui ʻia ka ʻenehana Dacromet no ka pale anti-corrosion, ʻoi aku hoʻi no nā screws a me nā mea paʻa. Hoʻohana nui ia e hoʻomaikaʻi i ka paʻakikī a me ka lōʻihi o nā huahana metala. Abrasiveness a me ka corrosion kū'ē. No nā mea hana me ka paʻakikī a me nā koi anti-corrosion, ʻoi aku ka pili o ka ʻenehana Crow. Ke koho ʻana i ka ʻenehana lapaʻau ili kūpono, pono e koho ʻia e like me nā koi noi kikoʻī.
