Ma hope o kapepa kila kilake kiʻi uea nei, e paʻa mau ana ia i ka pale ʻana i ka corrosion a me nā hopena pale pale.Eia naʻe, ke hoʻohālikelike ʻia me nā ʻāpana kila kila ʻaʻole i hana i ke kaha kiʻi uea, hiki ke emi iki ka hana.
I kēia manawa, ʻo nā lāʻau lapaʻau maʻamau maʻamau no nā ʻili kila kuhili ʻana he ʻili ʻālohilohi a me ka ʻili matte.ʻOi aku ke kūpaʻa o ka ʻaʻahu ʻana ma mua o nā ʻāpana kila kila ma hope o ka hoʻohana ʻana i ka uea.Eia naʻe, hiki ke emi mai ka hana ʻino a me ka pale ʻana i ka ʻōpala o nā ʻāpana kila ma hope o ka hoʻopaʻa ʻana i ka uea.ʻO ka mālama pono ʻole ʻana i ka wā hiki ke alakaʻi i ka ʻōpala mua i hoʻohālikelike ʻia me ka ʻili māmānā ʻili ʻili kila.
Kila kohu ʻoleʻO ia kekahi o nā kila kuhili ʻole austenitic, i haku nui ʻia me nā mea e like me carbon, nickel, a me chromium.Hiki i ka Chromium ke hana i kahi kiʻiʻoniʻoni pale waiwai nui o ka chromium ma luna o ka ʻili o nā ʻāpana kila kila, e pale ana i ka hoʻoneʻe ʻana a me ka corrosion.Hiki ke hoʻopōʻino i ke kiʻi ʻoniʻoni pale chromium ma ka ʻili o ke kaha kiʻi uea, e alakaʻi ana i ka emi ʻana o ka pale ʻana i ka corrosion a me ka hana pale ʻana i ka hana ʻana o nā ʻāpana kila kila.Ma nā wahi paʻakikī me ka ʻike ʻana i ka makani, ka lā, a me ka ua, hiki ke maʻalahi ka pala a me ka ʻōpala.
Ma mua o ka hana ʻana i ka lāʻau kiʻi uea ma nā ʻāpana kila kuhili ʻole, pono ia e hoʻopili i ka lapaʻau pale passivation rust.Hoʻokumu ʻia ka lapaʻau ʻana i ka passivation ma luna o ke kumumanaʻo kiʻiʻoniʻoni lahilahi, e hōʻike ana i ka hele ʻana o ka passivation i ka wā e launa pū ai ke metala me ka mea waena, a laila e hoʻokumu ʻia kahi kiʻiʻoniʻoni passivation ʻoi loa, paʻa, uhi maikaʻi ma ka ʻili metala.Ke hana nei kēia kiʻiʻoniʻoni ma ke ʻano he mea pale, pale i ka pilina pololei ma waena o ka metala a me ka corrosive medium a me ka pale ʻana i ka metala mai ka corrosion.
