ʻO ka Super Stainless Steel a me ka nickel-based alloys nā ʻano kūikawā o ke kila kila.ʻO ka mea mua, ʻokoʻa kemika mai ke kila kuhili ʻole maʻamau.E pili ana i ke kila kila kila kila kiʻekiʻe me ka nickel kiʻekiʻe, ka chromium kiʻekiʻe, ka molybdenum kiʻekiʻe.
Wahi a nā hiʻohiʻona microstructure o nā mea kila kila, ua hoʻokaʻawale ʻia ke kila kila kila super ferritic stainless steel, super austenitic stainless steel, super martensitic stainless steel, super duplex stainless steel a me nā ʻano ʻē aʻe.
He kila kuhili ʻole austenitic
Ma ke kumu o ke kila kila austenitic maʻamau, ma ka hoʻomaikaʻi ʻana i ka maʻemaʻe o ka alloy, ka hoʻonui ʻana i ka nui o nā mea pono, e hōʻemi ana i ka ʻike o C, e pale i ka ua o Cr23C6 i hoʻokumu ʻia e ka intergranular corrosion, loaʻa nā waiwai mechanical maikaʻi, nā waiwai kaʻina a me ke kūpaʻa corrosion kūloko. , e pani i ke kila kila kuʻeʻe Ti.
He kila kuhiliʻole super ferritic
Loaʻa iā ia nā hiʻohiʻona o ka ikaika kiʻekiʻe, ke kūpaʻa oxidation maikaʻi a me ke kūpaʻa koʻikoʻi koʻikoʻi koʻikoʻi o ke kila kila ferritic maʻamau.I ka manawa like, hoʻomaikaʻi ia i nā palena o ka ferrite stainless steel i ke kūlana kuʻi ʻana o ka brittle transition, sensitive i ka intergranular corrosion a me ka haʻahaʻa haʻahaʻa.Hiki ke kiʻi ʻia ke kila kila ultra-ferritic me ka Cr kiʻekiʻe, Mo a me ka ultra haʻahaʻa C a me N ma o ka hoʻomaʻemaʻe ʻana i ka ʻenehana, e hōʻemi ana i ka ʻike o C a me N, me ka hoʻohui ʻana a me ka hoʻohui ʻana i nā mea hoʻoikaika metala.ʻO ka hoʻohana ʻana i ke kila kila ferritic i ka pale ʻana i ka corrosion a me ka pale ʻana o ka chloride corrosion ua komo i kahi pae hou.
He kila kuhiliʻole super duplex
Ua kūkulu ʻia ke kila i ka hopena o 1980s.ʻO nā hōʻailona nuiʻo SAF2507, UR52N, Zeron100, a me nā mea'ē aʻe, iʻikeʻia e ka haʻahaʻa C haʻahaʻa, kiʻekiʻe Mo kiʻekiʻe a me N kiʻekiʻe.ʻO ka maʻiʻo ferritic phase i loko o ke kila he 40% ~ 45%., me ka pale ʻana i ka corrosion maikaʻi loa.
He kila kuhiliʻole super martensitic
He kila kuhiliʻole paʻakikī me ka paʻakikī kiʻekiʻe, ka ikaika a me ke kūpaʻa ʻana, akā ʻilihune ka paʻakikī a me ka weldability.ʻAʻole lawa ka ductility martensitic maʻamau, pili loa i ke koʻikoʻi i ka wā deformed, a paʻakikī ke hana ʻia i ka hana anu.Ma ka hōʻemi ʻana i ka ʻike kalapona a me ka hoʻonui ʻana i ka nickel content, hiki ke loaʻa ke kila kila kila super martensitic.I nā makahiki i hala iho nei, ua hoʻolilo nā ʻāina i ke kālā he nui i ka hoʻomohala ʻana i ke kalapona haʻahaʻa a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa super martensitic kila, a hoʻomohala i kahi pūʻulu kila super martensitic no nā kumu like ʻole.Ua hoʻohana nui ʻia ke kila super martensitic i ka hoʻohana ʻana i ka aila a me ke kinoea, ka mālama ʻana a me ka lawe ʻana i nā lako, hydropower, ʻoihana kemika, nā mea hana pulp kiʻekiʻe wela a me nā māla ʻē aʻe.
He kila kuhiliʻole hana
Me ka hoʻololiʻana o ka makemake o ka mākeke, e hoʻomauʻia ana keʻano o ke kila kila me nā hoʻohana kūikawā a me nā hana kūikawā.E like me ka nickel hou manuahi austenitic kuhiliʻole kila mea nui Cr-Ni austenitic kuhiliʻole kila, he maikaʻi biocompatibility, i loko o Ni 13% ~ 15%.ʻO Nickel kahi ʻano mea sensitizing, he teratogenic a he carcinogenic i nā meaola.ʻO ka hoʻohana lōʻihi ʻana i ka nickel-containing stainless steel e hoʻopau mālie a hoʻokuʻu i nā ion Ni.Ke hoʻonui ʻia nā Ni ion i loko o nā ʻiʻo kokoke i ke kanu ʻana, hiki ke hoʻoulu ʻia nā hopena ʻawaʻawa a hiki i nā hopena ʻino e like me ka luku ʻana i nā cell a me ka mumū.ʻO ka Cr-Mn-N medical nickel-free austenitic stainless steel i hoʻomohala ʻia e Institute of Metal Research, Chinese Academy of Sciences ua hoʻāʻo ʻia no ka biocompatibility, a ʻoi aku ka maikaʻi o kāna hana ma mua o ka Cr-Ni austenitic stainless steel i ka hoʻohana lāʻau lapaʻau.ʻO kekahi laʻana he kila kuhiliʻole antibacterial.Me ka hoʻomaikaʻi ʻana i ke kūlana ola o nā kānaka, ʻoi aku ka nui o ka nānā ʻana o ka poʻe i ke kaiapuni a me ko lākou olakino ponoʻī, e hāpai ana i ka noiʻi a me ka hoʻomohala ʻana i nā mea antibacterial.Mai ka makahiki 1980, ua hoʻomaka nā ʻāina hoʻomohala i hōʻike ʻia e Iapana e aʻo a hoʻopili i nā mea antibacterial i nā mea pono hale, nā meaʻai, nā mea e pono ai i kēlā me kēia lā, nā mea ʻauʻau a me nā mea ʻē aʻe.Ua hoʻomohala ʻo Nissin Steel a me Kawasaki Steel i ke kila kuhiliʻole antibacterial i loaʻa ka cu a me ka ag.Copper antibacterial kuhiliʻole kila ua hoʻohui 'ia i ka kuhiliʻole kila 0.5% ~ 1.0% keleawe, ma hope o kūikawā wela lapaʻau, no laila, i ka kuhiliʻole kila mai ka ili i loko o ka lole.ʻO ka hoʻopuehu ε-Cu precipitates he hana antibacterial.ʻO kēia keleawe i loaʻa ke kila stainless antibacterial e kūpono i nā ʻano huahana e like me nā lako kīhini premium, a me nā huahana ʻē aʻe me nā koi kiʻekiʻe no ka hana ʻana i nā waiwai a me nā waiwai antibacterial.
