Cobalt isimbi inopenya-grey simbi, yakaoma uye ine brittle, ferromagnetic, uye yakafanana nesimbi uye nickel mukuoma, kusimba kwesimba, mechanical properties, thermodynamic properties, uye electrochemical maitiro.Iyo magnetism inonyangarika kana ichipisa kusvika 1150 ℃.Iyo yakanaka simbi cobalt poda inogadzirwa nehydrogen yekudzikisa maitiro inogona kungoerekana yabatidza mucobalt oxide mumhepo.Oxidation inoitika pakupisa kwakanyanya.Kana inopisa, cobalt inopindirana nechisimba neokisijeni, sulfuri, chlorine, bromine, nezvimwewo, kuti iite makemikari anoenderana.Cobalt inonyungudika mu dilute acids uye inopfuudzwa mukupfuta nitric acid nekugadzira firimu reoxide.Cobalt inodzika zvishoma nezvishoma nehydrofluoric acid, ammonia uye sodium hydroxide.Cobalt chinhu chakakosha mbishi kugadzirwa kwearoyi anodzivirira kupisa, ma alloys akaomarara, anti-corrosion alloys, magineti alloys uye akasiyana cobalt munyu.Cobalt isimbi amphoteric.

Iyo yemuviri uye yemakemikari zvimiro zvecobalt inoona kuti yakakosha mbishi pakugadzirwa kweasingapi kupisa alloys, simende carbide, anti-corrosion alloys, magineti alloys uye akasiyana cobalt munyu.Cobalt-based alloy kana cobalt-ine alloy simbi inoshandiswa semashizha, impellers, conduits, jet engines, rocket engines, missile components uye zvakasiyana-siyana zvepamusoro-mutoro zvinodzivirira kupisa mumichina yemakemikari uye zvinhu zvinokosha zvesimbi muindasitiri yesimba reatomu.Cobalt sebhainda muupfu metallurgy inogona kuve nechokwadi chekuti simende carbide ine kumwe kuoma.Magnetic alloys zvinhu zvakakosha mumaindasitiri emazuva ano emagetsi uye emagetsi, anoshandiswa kugadzira zvakasiyana siyana zveacoustic, optical, magetsi uye magineti michina.Cobalt zvakare chikamu chakakosha chekusingaperi magineti alloys.Muindasitiri yemakemikari, cobalt inoshandiswa kuwedzera kune superalloys uye anti-corrosion alloys, asiwo yemavara egirazi, pigments, enamel uye catalysts, desiccant uye zvichingodaro.Uye zvakare, kushandiswa kwecobalt kune yakanyanya kukura mwero muchikamu chebhatiri.

Iyo cobalt yesimbi inonyanya kushandiswa kugadzira alloys.Cobalt base alloy ishoko rakajairwa kune imwechete kana akati wandei alloys akagadzirwa necobalt uye chromium, tungsten, iron uye nickel.Iyo simbi yemidziyo ine imwe huwandu hwecobalt inogona kuvandudza zvakanyanya kupfeka kuramba uye kucheka kuita kwesimbi.Starlite carbide ine inodarika 50% cobalt haizorasikirwe nekuoma kwayo kwepakutanga kunyangwe ichipisa kusvika 1000 ° C, uye ikozvino iyi carbide yave chinhu chakakosha zvikuru chinoshandiswa pakati pegoridhe-ine midziyo yekucheka nealuminium.Mune ichi chinyorwa, cobalt inosanganisa imwe simbi carbide zviyo mu alloy kuumbwa, kuitira kuti alloy ive nepamusoro kuoma uye inoderedza kunzwisiswa kwekukanganisa.Iyi alloy inosanganiswa uye yakasungirirwa pamusoro pezvikamu, izvo zvinogona kuwedzera hupenyu hwezvikamu ne3 kusvika ku7 nguva.Iyo inonyanya kushandiswa alloys mune aerospace tekinoroji ndeye nickel-based alloys, uye cobalt-based alloys inogona kushandiswa zvakare, asi "simba remagetsi" rearoyi maviri akasiyana.Simba renickel-based alloys rine titanium nealuminium rakakwira nekuda kwekuumbwa kwechikamu chekuomesa chinoumbwa neNiAl (Ti), kana tembiricha yekushanda yakakwira, chikamu chekuomesa mumiriri chinoendeswa kune yakasimba mhinduro, ipapo alloy inokurumidza kupera simba.Kupisa kwekupisa kwe-cobalt-based alloys kunokonzerwa nekuumbwa kwerefractory carbides, iyo isiri nyore kushanduka kuva mhinduro dzakasimba, uye basa rekupararira idiki.Kana tembiricha iri pamusoro pe1038 ° C, zvakanakira cobalt-based alloys zvinoratidzwa zvizere.Nokuda kwepamusoro-soro, injini yekupisa, cobalt-based alloys yakarurama.
