Mmalite nke igwe anaghị agba nchara

Brearley chepụtara igwe anaghị agba nchara na 1916 nwetara patent nke Britain wee malite imepụta oke, ka ọ dị ugbu a, igwe anaghị agba nchara na mberede a chọtara n'ime mkpofu ghọrọ ewu ewu n'ụwa niile, Henry Brearley na-akpọkwa "nna nke igwe anaghị agba nchara".N'oge Agha Ụwa Mbụ, a na-ezigara égbè Britain n'ọgbọ agha mgbe niile n'azụ n'ihi na ụlọ ahụ na-eyi ya ma ghara iji ya eme ihe.Ngalaba mmepụta ndị agha nyere iwu ka mmepe nke ike dị elu na-eguzogide alloy steel Breer Li, ọkachamara na-edozi nsogbu nke eyi.Brearley na onye inyeaka ya chịkọtara ụdị nchara dị iche iche na-emepụta n'ụlọ na mba ọzọ, ụdị dị iche iche dị iche iche nke alloy steel, n'ụdị ụdị ọrụ dị iche iche nke nnwale arụmọrụ, wee họrọ nchara dabara adaba n'ime egbe.Otu ụbọchị, ha nwalere ụdị nchara ụlọ nwere ọtụtụ chromium.Ka e mechara ule na-eguzogide iyi, achọpụtara na alloy a anaghị egbochi uwe, na-egosi na a pụghị iji ya mee egbe.Ya mere, ha dekọtara nsonaazụ nnwale ahụ wee tụba ha n'otu akụkụ.Otu ụbọchị, ọnwa ole na ole ka e mesịrị, otu onye inyeaka ji ígwè na-egbuke egbuke gbagara Brearley."Nna anyị ukwu," ka o kwuru, "Achọtara m alloy n'aka Mr. Mullah mgbe m na-ehichapụ ụlọ nkwakọba ihe. Ọ ga-amasị gị ịnwale ya iji hụ ihe pụrụ iche eji ya eme!""Ọ dị mma!"Brearley kwuru obi ụtọ, na-ele nchara na-egbuke egbuke.

Nsonaazụ nnwale na-egosi na ọ naghị atụ egwu acid, alkali, nnu igwe anaghị agba nchara.Onye German mullah chepụtara igwe anaghị agba nchara na 1912, mana mullah amaghị ihe ọ bụ.

Brearley nọ na-eche, sị: "Enwere ike iji ụdị ígwè a, nke na-adịghị egbochi ya ma na-eguzogide corrosion, maka tableware, ọ bụghị maka egbe?"O kwuru na akọrọ nkụ, malite ime mma mkpụrụ osisi anaghị agba nchara, ndụdụ, ngaji, efere mkpụrụ osisi na mma mpịachi.

Ugbu a ngwa ngwa nke igwe anaghị agba nchara na-arịwanye elu, ihe a na-achọsi ike na-arịwanye elu, mgbe ahụ nke na-esote bụ ikwu maka nhazi na ntinye nke igwe anaghị agba nchara.

Ọla niile na-emeghachi omume na ikuku oxygen na ikuku iji mepụta ihe nkiri oxide n'elu.N'ụzọ dị mwute, ígwè oxide nke na-etolite na ígwè carbon nkịtị na-aga n'ihu oxidize, na-ekwe ka corrosion gbasaa ma mesịa mepụta oghere.Enwere ike idobe elu igwe carbon site na iji agba ma ọ bụ ọla na-eguzogide oxidization dị ka zinc, nickel na chromium, ma, dị ka a maara, nchebe a bụ naanị ihe nkiri dị mkpa.Ọ bụrụ na agbajikwa mkpuchi nchebe, nchara dị n'okpuru na-amalite nchara.

Na-eguzogide ikuku, uzuoku, mmiri na ndị ọzọ na-adịghị ike corrosive ọkara na acid, alkali, nnu na ndị ọzọ chemical corrosive ọkara corrosion nke ígwè.A makwaara dị ka igwe anaghị agba nchara - ígwè na-eguzogide ọgwụ.Na ngwa bara uru, a na-akpọkarị igwe anaghị agba nchara nchara na-adịghị ike, a na-akpọkwa ígwè na-eguzogide ọgwụ na-eguzogide ọgwụ acid.N'ihi ọdịiche dị na ihe mejupụtara kemịkalụ, nke mbụ abụghị ihe na-eguzogide ọgwụ mgbochi corrosion, ebe nke ikpeazụ na-eguzogide nchara n'ozuzu.Nguzogide corrosion nke igwe anaghị agba nchara 2 na-adabere na ihe ndị na-emepụta ihe dị na ígwè.Chromium bụ isi ihe na-eme ka igwe anaghị agba nchara nguzogide corrosion.Mgbe ọdịnaya chromium dị na nchara ruru ihe dịka 12%, chromium na oxygen na ihe na-emebi emebi na-emeghachi ihe nkiri oxide dị ezigbo mkpa (ihe nkiri na-eme onwe ya) n'elu nchara, nke nwere ike igbochi corrosion ọzọ nke matrix ígwè.Na mgbakwunye na chromium, ihe alloy na-ejikarị na nickel, molybdenum, titanium, niobium, ọla kọpa, nitrogen, wdg, iji mezuo ihe achọrọ dị iche iche nke usoro igwe anaghị agba nchara na arụmọrụ.

Abụọ, nhazi nke igwe anaghị agba nchara na-ekewakarị n'ime:

1. Ferritic igwe anaghị agba nchara.Chromium 12% ~ 30%Nguzogide corrosion ya, ike siri ike na weldability na-abawanye site na mmụba nke ọdịnaya chromium, yana nguzogide nrụgide chloride dị mma karịa igwe anaghị agba nchara ndị ọzọ.
2. Austenitic igwe anaghị agba nchara.O nwere ihe karịrị 18% chromium, 8% nickel na obere molybdenum, titanium, nitrogen na ihe ndị ọzọ.Ezigbo arụmọrụ zuru oke, nwere ike iguzogide corrosion nke mgbasa ozi dị iche iche.
3. Austenitic ferrite duplex igwe anaghị agba nchara.Ọ nwere uru nke austenitic na ferritic igwe anaghị agba nchara, na nwere superplasticity.
4. Martensitic igwe anaghị agba nchara.Ike dị elu, mana plasticity adịghị mma na weldability.

Atọ, njirimara na ojiji nke igwe anaghị agba nchara.

Anọ, igwe anaghị agba nchara usoro elu.
