Indima ye-Chromium kwi-Stainless Steel

Ukuthi stainless steel ingena emvelweni kungenxa yokuba uphela kakhulu nge-chromium. I-Chromium iyisilinda esibonakalayo esithinte oksijeni ukwenza ubushesha obuvikelayo kwinhloso yesilinda, okuyindlela yokuba iphumele.

Ukwenza kwe-Passive Layer : Xa stainless steel inamanye amakhromiyamu kakhulu (okungenani 10.5% okudingekayo ukungena emvelweni), ikhromiyamu ithinte oksijeni kuhlangothini noma kamanzi ukwenza ubushesha obutinye obungangekho ukubona obunqumayo okuthiwa ngokuthi chromium oxide (Cr₂O₃). Le mithwana ngokuthiwa yi-“passive layer” ngisho naye yenza isilinda singene emvelweni, okuthi yenza ukuthi sibeke ukuthinte nenhawu.
Inkorekisa yokuthula : Uma umbane wesilika uma kuchithwa noma kugcinwe (isb., ngekuchaza noma kugcwala), ikhromiyamu kwiingceke imithi iyahlukisa kancinca ne-oksijeni futhi ukwenze umbane kabusha. Qaphela ukuthi kune oksijeni nangokwengekhromiyamu, umbane wesilika uphinde ukuhlelwe, ukunika amathuba okungena. Le ndawo yokulungisa ngokwakhe yindlela ecacileyo yomoya wesilika kwaye inikeza ukuphepha okudala.
Ikhromiyamu Eningi Iyakunika Ukukhululeka Okuningi : Iindlela zesilika zokuba nekhromiyamu enkulu (isb., 18% noma ngaphezulu) zenza umbane wesilika uphawu, okuyinkinga. Le ndlela isetshenziselwa kizindawo eziphazamisa kakhulu, njengokwemadolobha nezindawo zokwenza izinhlelo, lapho kudingeka ukuphepha okuningi.

Ilaya yesilika yekhromiyamu iyinkimbinkimbi yokukhululeka kwezilika, yenza ukuthi kube yimali kakhulu kuno-carbon steel lapho kunezimo ezithile noma ezimbonde.

Ezinye Iindlela Zokwenza Ukukhululeka Okuningi

Noma ukuthi i-chromium yinkomba esikhundleni, amanye amaloyi esiSteni yesiliva sasemgangeni kwehlela ukulingana kwayo nezinhloso zokusebenza kuzo nezimo ezithile.

I-nickel : Ukudibanisa i-nickel (kutholakale kakhulu kumagrade esiSteni yesiliva se-austenitic njenge-304 ne-316) isekela umqondo wesiSteni, kuyenza kube yimali futhi kuyahlukahluka. I-nickel nakho isenza ubungqina baleli qhuma ukulingana kwayo kuzo nezimo eziphambene ne-acidic noma alkaline, lokhu kwenza lezi grade ziphumelele kuzo zindlela zokubhantsha noma amatanki esiManzini.
I-Molybdenum : I-Molybdenum idibaniselwa esiSteni yesiliva (isb., i-grade 316) ukulehla ukulingana kwayo kuzo ukuphunzwa, lo msebenzi we-localized owakhiwe yi-chloride ions esiManzini, esiGqamane, noma kuzo izinhlelo zokwenza izimpahla. Lokhu kwenza i-stainless steel enezi-Molybdenum iphumelele kuzo amasipho esiNtshonalanga, amasipho esibhakabhaka, noma izinhlelo zokubona okuthintana nezinto zokudla.
I-Titanium noma i-Niobium : Lezi zinto ukuvikela ukwenyenzelwa, into lapho i-chromium carbides ikhiwe kuzo ezinsukwini zokugqoka, ukwenza i-chromium ephakathi kwezinsukwi ingaphansi futhi yenza ukungcola okungahlanjiswa. Iindlela ze-stainless steel zenziwe nge-titanium noma niobium (isb., 321) zihlala kusetshenziselwa kuzo ezinhlotyeni zokugqoka njengoba amathambu noma amatanki, ukuthi ilaye elibhakabhake i-passive iyahlala yekhona noma ngemva kokuqhubeka ngokusheshayo.
Initirojjeni : Initirojjeni iyenza amandla esi-stainless steel futhi iyenza ukungcola kwayo kwezindlela eziningi nezindlela zokungcola, zisetshenziselwa kakhulu kuzo izingxenye ezinamandla kuzo zokusebenza kwezokulayishwa kwezimali ezingenakuphansi.

Lezi zinto zokudityanisa zisebenza ngokwengeza nge-chromium ukulungiselela ukungcola kwe-stainless steel ukuze ikhankanye izidingo eziyisikali, kusukela ekusebenzeni ngokwesikhathi sizoqobo kuzo zokusebenza kwezimali eziningi.
