I-Cobalt iyinsimbi ecwebezelayo empunga, eqinile futhi eshwabene, i-ferromagnetic, futhi efana nensimbi ne-nickel ngobulukhuni, amandla aqinile, izakhiwo zemishini, izakhiwo ze-thermodynamic, nokuziphatha kwe-electrochemical.I-magnetism iyanyamalala lapho ishiselwa ku-1150 ℃.I-metallic cobalt powder enhle ekhiqizwa inqubo yokunciphisa i-hydrogen ingathungela ngokuzenzekelayo ibe yi-cobalt oxide emoyeni.I-oxidation ivela emazingeni okushisa aphezulu.Uma ishiswa, i-cobalt isabela ngobudlova ne-oxygen, isulfure, i-chlorine, i-bromine, njll., ukuze yakhe izinhlanganisela ezihambisanayo.I-cobalt iyancibilika kuma-asidi acwebileyo futhi idluliswa ekufutheni kwe-nitric acid ngokwenza ifilimu ye-oxide.I-Cobalt ifakwe kancane kancane yi-hydrofluoric acid, i-ammonia ne-sodium hydroxide.I-Cobalt iyinto ebalulekile yokukhiqiza ama-alloys angavimbeli ukushisa, ama-alloys aqinile, ama-anti-corrosion alloys, ama-alloys magnetic kanye nosawoti ohlukahlukene we-cobalt.I-Cobalt iyinsimbi ye-amphoteric.

Izakhiwo ezingokwenyama namakhemikhali e-cobalt zinquma ukuthi iyimpahla ebalulekile yokukhiqiza ama-alloys ukumelana nokushisa, i-carbide enosimende, ama-anti-corrosion alloys, ama-alloys magnetic kanye nosawoti ohlukahlukene we-cobalt.I-cobalt-based alloy noma i-cobalt-containing alloy steel isetshenziswa njengama-blade, ama-impeller, ama-conduits, izinjini ze-jet, izinjini ze-rocket, izingxenye ze-missile kanye nezingxenye ezihlukahlukene ezithwala ukushisa okuphezulu emishini yamakhemikhali nezinto ezibalulekile zensimbi embonini yamandla e-athomu.I-cobalt njenge-binder ku-powder metallurgy ingaqinisekisa ukuthi i-carbide enosimende inokuqina okuthile.Ama-alloys kazibuthe ayizinto ezibalulekile ezimbonini zesimanje ze-elekthronikhi kanye ne-electromechanical, ezisetshenziselwa ukwakha izingxenye ezihlukahlukene zemishini ye-acoustic, optical, kagesi kanye nekazibuthe.I-Cobalt nayo iyingxenye ebalulekile yama-alloys magnetic unomphela.Embonini yamakhemikhali, i-cobalt isetshenziswa ngaphezu kwama-superalloys nama-anti-corrosion alloys, kodwa futhi ingilazi enemibala, izingulube, koqweqwe lwawo kanye nama-catalysts, i-desiccant nokunye.Ngaphezu kwalokho, ukusetshenziswa kwe-cobalt kunezinga eliphezulu lokukhula emkhakheni webhethri.

I-cobalt yensimbi isetshenziswa ngokuyinhloko ukwenza ama-alloys.I-cobalt base alloy yigama elijwayelekile lengxubevange eyodwa noma eminingana eyenziwe nge-cobalt ne-chromium, i-tungsten, insimbi ne-nickel.Insimbi yensimbi equkethe inani elithile le-cobalt ingathuthukisa kakhulu ukumelana nokugqoka nokusebenza kokusika kwensimbi.I-Starlite carbide equkethe i-cobalt engaphezu kuka-50% ngeke ilahlekelwe ubulukhuni bayo bangempela ngisho noma ishisa ku-1000 ° C, futhi manje le carbide isiyinto ebaluleke kakhulu esetshenziswa phakathi kwamathuluzi okusika anegolide ne-aluminium.Kulesi sihloko, i-cobalt ihlanganisa ezinye izinhlamvu zensimbi ze-carbide ekubunjweni kwe-alloy, ukuze ingxube ibe nokuqina okuphezulu futhi inciphise ukuzwela komthelela.Le alloy ihlanganiswe futhi ishiselwe ebusweni bezingxenye, ezingandisa impilo yezingxenye izikhathi ezi-3 kuya kweziyi-7.Ama-alloys asetshenziswa kakhulu kubuchwepheshe be-aerospace ama-alloys asekelwe ku-nickel, futhi ama-alloys asekelwe ku-cobalt angasetshenziswa, kodwa "indlela yamandla" yama-alloys amabili ihlukile.Amandla ama-alloys asekelwe ku-nickel aqukethe i-titanium ne-aluminium aphezulu ngenxa yokwakheka kwe-ejenti eqinisa isigaba esakhiwe i-NiAl(Ti), lapho izinga lokushisa lokusebenza liphezulu, izinhlayiya ze-agent eqinisa isigaba zidluliselwa kwisisombululo esiqinile, bese ingxubevange ilahlekelwa amandla ngokushesha.Ukumelana nokushisa kwama-alloys asekelwe ku-cobalt kubangelwa ukwakheka kwe-carbides ephikisayo, okungelula ukuphenduka izixazululo eziqinile, futhi umsebenzi wokusabalalisa uncane.Lapho izinga lokushisa lingaphezu kuka-1038 ° C, izinzuzo zama-alloys asekelwe ku-cobalt ziboniswa ngokugcwele.Ngokusebenza kahle kakhulu, izinjini zokushisa okuphezulu, ama-alloys asekelwe ku-cobalt alungile.
