I-Cobalt yintsimbi ecwebezelayo-engwevu, iqinile kwaye i-brittle, i-ferromagnetic, kwaye ifana nentsimbi kunye ne-nickel kubunzima, amandla okuqina, iimpawu zomatshini, iipropati ze-thermodynamic, kunye nokuziphatha kwe-electrochemical.Imagnethi iyanyamalala xa ishushubezelelwa kwi-1150 ℃.Umgubo ocolekileyo wesinyithi we-cobalt oveliswe yinkqubo yokunciphisa i-hydrogen unokuvutha ngokuzenzekelayo kwi-cobalt oxide emoyeni.I-oxidation iyenzeka kumaqondo obushushu aphezulu.Xa ishushu, i-cobalt iphendula ngokukhawuleza nge-oksijeni, isulfure, i-chlorine, i-bromine, njl., ukwenza iikhompawundi ezihambelanayo.I-Cobalt iyanyibilika kwi-acids edibeneyo kwaye igqithiswa kwi-asidi ye-nitric evuthayo ngokwenza ifilimu ye-oxide.I-Cobalt ifakwe kancinci yi-hydrofluoric acid, i-ammonia kunye ne-sodium hydroxide.I-Cobalt yinto ebalulekileyo ekrwada kwimveliso ye-alloys ekwazi ukumelana nokushisa, i-alloys eqinile, i-anti-corrosion alloys, i-alloys magnetic kunye neetyuwa ezahlukeneyo ze-cobalt.I-Cobalt yintsimbi ye-amphoteric.

Iimpawu ezibonakalayo kunye neekhemikhali ze-cobalt zinquma ukuba yinto ebalulekileyo ekrwada kwimveliso ye-alloys enganyangeki ukushisa, i-carbide ene-cemented, i-anti-corrosion alloys, i-alloys magnetic kunye neetyuwa ezahlukeneyo ze-cobalt.I-alloy esekelwe kwi-cobalt okanye i-cobalt-containing alloy steel isetyenziswe njengama-blades, i-impellers, i-conduits, ii-jet injini, iinjini ze-rocket, i-missile components kunye ne-high-load-high-load-resistant-resistant components kwi-chemical equipment kunye nezixhobo ezibalulekileyo zetsimbi kwishishini lamandla e-athomu.I-Cobalt njenge-binder kwi-powder metallurgy inokuqinisekisa ukuba i-carbide enesamente inobunzima obuthile.I-Magnetic alloys zizinto eziyimfuneko kumashishini anamhlanje e-elektroniki kunye ne-electromechanical, esetyenziselwa ukuvelisa izinto ezahlukeneyo ze-acoustic, i-optical, umbane kunye nezixhobo zemagneti.I-Cobalt nayo iyinxalenye ebalulekileyo ye-alloys esisigxina yamagnetic.Kwishishini lemichiza, i-cobalt isetyenziselwa ukongeza kwi-superalloys kunye ne-anti-corrosion alloys, kodwa kunye neglasi enemibala, i-pigments, i-enamel kunye ne-catalysts, i-desiccant kunye nokunye.Ukongeza, ukusetyenziswa kwe-cobalt kunelona zinga lokukhula okuphezulu kwicandelo lebhetri.

I-cobalt yensimbi isetyenziselwa kakhulu ukwenza i-alloys.I-Cobalt base alloy ligama eliqhelekileyo kwi-alloys enye okanye ezininzi ezenziwe nge-cobalt kunye ne-chromium, i-tungsten, isinyithi kunye ne-nickel.Isixhobo sensimbi esinexabiso elithile le-cobalt sinokuphucula kakhulu ukuxhatshazwa kokugqoka kunye nokusika ukusebenza kwentsimbi.I-Starlite carbide equkethe ngaphezu kwe-50% ye-cobalt ayiyi kulahlekelwa ubunzima bayo bokuqala nangona ishushu kwi-1000 ° C, kwaye ngoku le carbide ibe yinto ebaluleke kakhulu esetyenziswa phakathi kwezixhobo zokusika ezinegolide kunye ne-aluminium.Kulo mbandela, i-cobalt idibanisa ezinye iinkozo ze-carbide zensimbi kwi-alloy composition, ukwenzela ukuba i-alloy ibe nobunzima obuphezulu kunye nokunciphisa uvakalelo kwimpembelelo.Le alloy ixutywe kwaye idityaniswe kumphezulu wamacandelo, anokunyusa ubomi bamalungu ngama-3 ukuya ku-7 amaxesha.Ezona zixhobo zisetyenziswa kakhulu kwitekhnoloji ye-aerospace zi-alloys ezisekelwe kwi-nickel, kunye ne-alloys esekwe kwi-cobalt nayo ingasetyenziswa, kodwa "indlela yamandla" yee-alloys ezimbini yahlukile.Amandla e-alloys esekelwe kwi-nickel equkethe i-titanium kunye ne-aluminium iphezulu ngenxa yokubunjwa kwe-agent ye-agent eqiniweyo eyenziwe yi-NiAl (Ti), xa ubushushu bokusebenza buphezulu, iinqununu ze-agent ye-agent idluliselwe kwisisombululo esiqinileyo, emva koko i-alloy ngokukhawuleza ilahlekelwa amandla.Ukumelana nokushisa kwee-alloys ezisekelwe kwi-cobalt kubangelwa ukubunjwa kwe-carbides ephikisayo, akulula ukuyijika ibe yizisombululo eziqinileyo, kwaye umsebenzi wokusabalalisa uncinci.Xa iqondo lokushisa lingaphezulu kwe-1038 ° C, izibonelelo ze-cobalt-based alloys ziboniswa ngokupheleleyo.Ukusebenza okuphezulu, iinjini zobushushu obuphezulu, i-cobalt-based alloys ilungile.
