ʻO ke kila kūikawā,ʻo ia hoʻi, ke kila kūikawā,ʻo ia keʻano nui o ke kila i hoʻohanaʻia i ka nui o nāʻoihana o ka hoʻokele waiwai o ka'āina, e like me nā mīkini, nā kaʻa, nāʻoihana koa, nā mea kemika, nā mea hana hale, nā moku, ka laweʻana, nā kaʻaahi a me nāʻoihana e ulu nei.He hōʻailona koʻikoʻi ke kila kūikawā e ana inā hiki i kahi ʻāina ke lilo i hale mana kila.
ʻO ke kila kūikawā e pili ana i nā mea'ē aʻe e hana ana ma lalo o nā kūlana kūikawā a loaʻa nā koi kūikawā no ke kila, e like me ke kino, kemika, ka mechanical a me nā mea'ē aʻe.
ʻO nā kila hana kūikawā hoʻi nā kila kila kūikawā.ʻO kēia mau mea kila e pili ana i nā kila me nā hana electromagnetic, optical, acoustic, thermal a electrochemical a me nā hana.ʻO ka mea maʻamau, ʻo ke kila kila, ke kila wela, ke kila silikoni uila, ka hao maʻemaʻe uila a me nā ʻāpana ʻokoʻa like ʻole (nā ʻāpana magnetic palupalu, e like me nā alloys magnetic, nā ʻāpana elastic, nā ʻāpana hoʻonui, nā ʻāpana pālua wela, nā ʻāpana kūʻē, nā mea pākaukau mua, etc. .)..
Ua kapa ʻia ke kila kila no kona kūpaʻa ʻino maikaʻi, a ʻo kāna mau mea hoʻohui nui he chromium a me nickel.Loaʻa i ka Chromium ke kūpaʻa kemika kiʻekiʻe a hiki ke hana i kahi kiʻiʻoniʻoni hoʻomaʻemaʻe paʻakikī a paʻakikī i loko o kahi mea hoʻoheheʻe;Eia kekahi, i ka wā i ʻoi aku ka nui o ka chromium ma mua o 11.7%, hiki ke hoʻonui nui ʻia ka mana electrode o ka huila, a laila e pale pono ai i ka oxidation hou o ka alloy.ʻO Nickel kekahi mea kōkua.ʻO ka hoʻohui ʻana o ka nickel i ke kila chromium hiki ke hoʻomaikaʻi i ke kūpaʻa corrosion o ka alloy i ka media non-oxidizing.Ke mau ka maʻiʻo o ka chromium a me ka nickel, ʻoi aku ka haʻahaʻa o ke kalapona i loko o ke kila, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.
ʻO ke kūpaʻa corrosion o ke kila kila e pili pū ana me ka kūlike o ka hoʻolālā matrix.Ke hoʻokumu ʻia kahi hoʻonā paʻa paʻa like ʻole, hiki ke hoʻemi maikaʻi ʻia ka nui o ka corrosion o ke kila i loko o ka electrolyte.
ʻO ke kila kila Austenitic he kila chromium-nickel moʻo kila me ka hale austenitic hoʻokahi.Loaʻa iā ia ke kūpaʻa corrosion maikaʻi, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, kaomi hana a me ka hana kuʻi ʻana, non-magnetic, a hoʻohana nui ʻia e like me ke kila wela haʻahaʻa a me ke kila wela haʻahaʻa e hana ana i ka media corrosive.ʻO ke kila kilaʻole;ʻO ke kila kila ferritic ka nui o ka chromium, ka mea e hoʻololi ʻia i ka wā o ka hoʻomehana ʻana a me ka hoʻoluʻu ʻana, a he mea hoʻohana maʻamau i ka ʻaʻahu kūʻokoʻa i ka ʻoihana nitric acid a me ka nitrogen fertilizer;martensitic kuhiliʻole kila he kiʻekiʻe kalapona maʻiʻo a me ka maikai hardenability.Loaʻa kahi ʻano martensitic.ʻO kēia kila ka paʻakikī maikaʻi a me ke kalapona haʻahaʻa haʻahaʻa, a hiki ke hoʻohana ʻia e hana i nā ʻāpana kū i ka hopena e hana ana i ka media corrosive;hoʻohana ʻia ke kalapona kiʻekiʻe e hana i nā pūnāwai, nā bearings, nā ʻokiʻoki, etc.;Loaʻa iā ia kahi ʻano hui ʻelua o ka austenite a me ka ferrite.ʻO ke kila kila o ka matrix he duplex stainless steel, nona nā pono o ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, a me ke kū'ē i ka intergranular corrosion.Ma waena o lākou, hoʻohana nuiʻia ke kila 00Cr18Ni5Mo3Si2 i ka hanaʻana i nā mea hoʻololi wela a me nā condensers i ka hoʻomaʻemaʻeʻana i kaʻaila, ka mea hoʻomomona, ka pepa, kaʻaila, kemika a me nāʻoihana'ē aʻe, a ua hoʻohanaʻiaʻo 0Cr26Ni5Mo2 i ka hanaʻana i nā mea hanaʻino o ke kai;molybdenum, niobium, alakaʻi, keleawe a me nā mea ʻē aʻe i ka wā paʻakikī e hana iā lākou Ma hope o ke kinai ʻana a me ka mālama ʻana i ka wā kahiko, he ikaika kiʻekiʻe a paʻakikī, a hoʻohana nui ʻia e hana i nā pūnāwai, nā mea holoi, bellows, etc.
ʻO ke kila uila, ʻike ʻia hoʻi ʻo ke kila silika, he hao-silikona binary alloy me kahi kalapona ma lalo o 0.05%.Loaʻa iā ia nā hiʻohiʻona o ka hao liʻiliʻi liʻiliʻi, liʻiliʻi coercive ikaika, kiʻekiʻe magnetic permeability a me ka magnetic induction ikaika, a ʻo ia kekahi o nā mea maʻamau maʻamau i hoʻohana ʻia (no ka manawa pōkole a i ʻole ka hoʻonui pinepine ʻana).ʻO nā kumu nui e pili ana i ka hana ʻana o ke kila uila ʻo ia ka hoʻohui ʻana a me ke ʻano.ʻO ka silikoni ka mana nui loa i nā waiwai magnetic o ke kila uila.Ke hoʻohui ʻia ka 3.0% Si i ka hao maʻemaʻe, hoʻonui ʻia ka permeability magnetic e 1.6-2 mau manawa, hoʻemi ʻia ka nalowale o ka hysteresis e 40%, hoʻonui ʻia ka resistivity e 4 mau manawa (hiki ke hōʻemi i ka nalowale o kēia manawa), a me ka huina. emi ka hao.Pālua, akā, ua hoʻonui nui ʻia ka paʻakikī a me ka ikaika.ʻO ka maʻamau, ʻaʻole ʻoi aku ka nui o ka ʻike silika ma mua o 4.5%, inā ʻaʻole paʻakikī a paʻakikī ke hana.ʻO ka loaʻa ʻana o nā mea haumia ʻino (N, C, S, O, a me nā mea ʻē aʻe) e hoʻoneʻe i ka lattice distortion o ke kila, hoʻonui i ke koʻikoʻi, a keʻakeʻa i ke kaʻina hana magnetization, no laila e mālama pono ʻia ka ʻike o nā haumia.
Hoʻohana nui ʻia ke kila Silicon i nā ʻoihana uila e like me nā kaʻa, nā mea hoʻololi, nā mea uila, a me nā mea uila.Hoʻopili ʻia ka hapa nui i nā ʻāpana 0.3, 0.35, 0.5, me ka ʻōwili wela a me ke anu.ʻōwili anu
