Kiato konukōreko me ētahi atu āhuatanga. ore konukōreko

Konukōreko (Ni) - ko te āhuatanga matū o te wā pūnaha o Mendeleev, ngā nei i roto i te topu- Fe, Co, Ni. Nika ko te whakarewa o te tae ma ki te takatu ai hiriwa kite. haere te reira i pai ki ētahi atu konganuku ki te hanga i alloys i te wa ano.

Ko te huranga o te nika

i tuatahi kitea nika ore e te kēmihi i Sweden A. Cronstedt i 1751. Roa i mua i mohio pai ona kaikeri whakatuwhera i ore Saxony e waho titiro rite te parahi. I whakamahia te reira ki te hanga i te matomato hua steklovarami. Pinepine steelmakers o taua wa e ngana ana ki te tiki i roto o tenei koranu o parahi, engari kua kore to ratou nganatanga katoa. Na reira, i te mutunga o te rau tau XVII. ka nika whakarewa tona ingoa tuatahi - ". rewera ore" "kupfernikel", i iritihia tikanga tonu te whakahaere Mineralogist Cronstedt ki te tiki i te waikura matomato, a na te whakaiti o te muri i whiwhi e te nika iho.

tūhuratanga atu o te whakarewa wāhi pūtaiao Bergman. Te fariiraa i roto i tona ahua parakore, he mea e taea ki te whakapumautia e nga āhuatanga o konukoreko tata ki te āhuatanga o te rino. I roto i te taipitopito ake, ako tenei konganuku e te tahi atu kairangahau, mai Proust. Āta kimi i to ratou ngā āhuatanga, tae atu te mātotoru o te nika. I roto i te meka, te kupu "Nikkel" Ko te kaikeri kupu paru. mai te reira i i te Niccolaus faahuru ê, a mahi īngoa haavare, iwi tinihanga. Ko te tikanga tuarua o te kupu, ko "he wairua, he he," "mangere".

kiato konukōreko me ētahi atu āhuatanga

He āhuatanga pērā i te ukanga me te kōngohe sēniti. Ēnei āhuatanga hanga reira ngāwari ki te maka atu tona utu. Mai i te pepa whakarewa whiwhi me ngongo. Nika - he rauemi kaua roa. Ko tōna kaha kurut ko 450 MPa. Ko te kupu vysokoplastichen reira, a hoki he ātete te waikura nui. Ko te kawe ia waiariki o te nika ko 90,1 W / (m · K) (i te 25 ° C).

tokahuke keri uru o kanoirite pūmau rima. whakarōpūtia Konukōreko te rite konganuku taimaha. Nika kiato Ko 8902 kg / m ^3. Ko reira rua neke atu i taua o te Titanium, engari he rite ki te kiato o te parahi tona uara ā-tau.

Kei te hipoki nika waikura?

he ātete ki te pāmahana teitei sēniti. Ki te whakamahia i tēnei whakarewa i roto i te taiao ahumahi, kei te maha taupokina ai a reira ki te waikura kiriata, me te mohimohiraa moka iti. e kore e hipokina hoki te reira ki te waikura. e kore e mahi ki runga ki taua mea, me te waikawa - rānei organic inorganic ranei. e kore e Rust hipokina tenei whakarewa noa i roto i te waipiro wera. Na reira, Kei te maha whakamahia nika i roto i te ahumahi kai.

Hea kia ngohengohe ki te waikura nika?

I roto i te katoa i reira e te tahi mau taiao te wahi e ngaro ai te whakarewa. Tuatahi, ko reira wai moana. I tua atu, i te reira kino pānga te otinga pēhau kawakore. ai hoki te pūngāwhā te waikura, rongoā tote, te wai haukini.

alloys konukōreko

Tenei whakarewa Ko te tāpiri pai mō te maitai. faarahi te reira i tona ukanga me te kaha. Addition o konukoreko me chromium alloys whakarato ātete te waikura nui o steels. Whānui e whakamahia ana i roto i te ahumahi chromium-nika he kowiri tira, i te kupu i te taumata tiketike o te thermostability.

He matū mohiotia alloys te wahi nika ko te huānga matua. Kiato Konukōreko taea tona whakamahi i roto i alloys ki rino, te konumohe, konupora, chromium me te takawai. E whakamahia taua alloys mō te hanga hatete. E ratou he taumata tiketike o te uruhanga autō. whakamahia hoki i roto i te maka engineering rino, i roto i nei te tapiritia sēniti. production ahumahi o tenei whakarewa timata e pā ana ki te rau tau ki muri. Ko te kupu te whakamahia e pā ana ki 80% o te nika mo te whakaputa rino me te konukōreko alloys.

Ētahi atu mara o tono o whakarewa

Konukōreko me ona alloys e whakamahia mo te hanga o steels kowiri kore anake. Konganuku me alloys whakamahia ki tana whai wāhitanga i roto i te hanga o te taputapu matū, te pahi. Konumāmura me chromel he āhuatanga wāhanga o taputapu whare: toasters, rino, me hatete wāhi. E whakamahia Ētahi alloys i te hanga o oko moana. He whakapaipai maha coatings sēniti.

tāoke whakarewa

Ko te nui o te nika kia whai paanga kino i runga i te tinana. Nui haere tona ihirangi i roto i te kai e taea te kōrero e pā ana ki te riri tika ki te hauora. Ko te putanga tino auau o te whakapā nui ki te tinana konukōreko - ko reira he mate pāwera. reira ai hoki Bronchitis, mate tākihi, me pukupuku pūkahukahu. Ko faaite nika tāoke iho anake, ki te he te reira i roto i te tinana i roto i ngā rahinga nui.
