Insimbi engagqwali idume ngokuqina kwayo, ukumelana nokugqwala, kanye nokukhanga kobuhle. Kodwa-ke, akuzona zonke izinsimbi ezingabiza isiqalo esihloniphekile "esingenasici". Isici esisodwa esibalulekile esinquma ukuthi insimbi iyafaneleka yini njengokungenabala okuqukethwe kwe-chromium.
I-Chromium idlala indima ebalulekile ekuguquleni insimbi evamile ibe yinsimbi engagqwali. Ukuze uthole isihloko esingenasici, insimbi kufanele ibe nephesenti elincane le-chromium. Ezimweni eziningi, insimbi engagqwali idinga okungenani i-chromium engu-10.5% ukuze ivimbele ukwakheka kokugqwala ngempumelelo. Lo mngcele usungula isisekelo sezakhiwo zensimbi ezingagqwali, okuyenza ifanelekele ukusetshenziswa okuhlukahlukene.
Ukwengezwa kwe-chromium ensimbi kudala isendlalelo se-oxide esivikelayo endaweni, eyaziwa ngokuthi ungqimba lwe-passive. Lesi singqimba sisebenza njengesivikelo ezintweni ezibolayo njengomswakama nomoya-mpilo. Ngaphandle kwalesi sithiyo esivikelayo, insimbi ijwayele ukugqwala futhi yonakale. Ngokuhlanganisa i-chromium, insimbi engagqwali izuza ukumelana okuphakeme nokungcoliswa, ukungcolisa, nokufaka imigodi, iqinisekisa ukuphila isikhathi eside nokuthembeka ezindaweni ezihlukahlukene.
Ngaphezu kwalokho, ukuba khona kwe-chromium kuthuthukisa amandla nokuqina kwensimbi. Le ngxenye ye-alloying ithuthukisa izakhiwo zensimbi, iyenze ibe namandla futhi iqine uma iqhathaniswa namabanga ensimbi avamile. I-synergy phakathi kwe-chromium nezinye izici ze-alloying icolisa i-microstructure yensimbi engagqwali, okuholela ezicini zokusebenza ezithuthukisiwe.
Ezimbonini ezisukela ekucutshungulweni kokudla kuye ezakhiweni, izimfanelo ezihlukile zensimbi engagqwali zikwenza kube ukukhetha okuncanyelwayo kwezinhlelo zokusebenza ezibucayi. Ikhono lokumelana nezimo ezinzima, ukugcina izindinganiso zokuhlanzeka, nokumelana nokuchayeka kumakhemikhali kugcizelela ukubaluleka kwe-chromium ekukhiqizweni kwensimbi engagqwali. Kungakhathaliseki ukuthi isetshenziswa ku-cutlery, amathuluzi ezokwelapha, izakhiwo zezakhiwo, noma izingxenye ze-aerospace, ukuguquguquka kwensimbi engagqwali kusuka ekwakhiweni kwayo okunothiswe yi-chromium.
Sengiphetha, ukufakwa kokuqukethwe kwe-chromium okungenani okungu-10.5% kuhlukanisa insimbi engagqwali kozakwabo abavamile. Le ngxenye ye-alloying inika amandla insimbi ukumelana nokugqwala, ukuqina, namandla, iyibeka eceleni njengento ephambili ngezinjongo ezahlukahlukene zezimboni nezasekhaya. Ukuhlanganiswa kwesayensi nensimbi ekukhiqizweni kwensimbi engagqwali kugcizelela indima ebalulekile ye-chromium ekulolongeni ubunjiniyela besimanje nezinqubo zokuklama.
