Ibisobanuro:
Co 21, inkoni yambaye ishingiye kuri cobalt ikora alloy ya austenitic ifite ubushobozi bwo gukomera, ifite imbaraga nyinshi mu bushyuhe kandi irinda ingaruka. Co 21 deposits irahoraho mu gihe cy'ubushyuhe, bigatuma iba amahitamo meza ku bikoresho bishyushye. Ikoreshwa ku byuma bigenzura umwuka n'amazi n'intebe. Ishobora gukoreshwa ku byuma byose bishobora gusukurwa, harimo n'ibyuma bitarangirika. Ingana na: Stellite 21, Polystel 21.
IBIKORESHO:
Valves z'umuyaga. Ibikoresho bishyushye. Imashini zikora ibikoresho byo gucura. Amamashini acukura. Valves z'ubutabire n'iza peteroli.

Cobalt 6
ECoCr-A electrodes zirangwa n'imiterere idahinduka, igizwe n'urusobe rwa karubide ya chromium eutectic igera kuri 13% ikwirakwijwe muri matrix ya cobalt-chromium-tungsten solid solution. Umusaruro ni ibikoresho bifite uruvange rw'ubudahangarwa rusange bwo kwangirika gukomeye, hamwe n'ubukomere bukenewe kugira ngo birwanye ingaruka runaka. Cobalt alloys nazo ni nziza mu kurwanya kwangirika kw'icyuma kuva ku cyuma kugera ku cyuma, cyane cyane mu bihe by'umutwaro mwinshi bishobora gutera ubushuhe. Ingano y'ingufu nyinshi muri matrix inatanga ubudahangarwa bwiza bwo kwangirika, oxidation, no kugumana ubushyuhe bwinshi kugeza kuri 1200°F (650°C). Izi alloys ntizihinduka allotropic bityo ntizitakaza imiterere yazo niba icyuma cy'ibanze gishyushye nyuma.
Colbalt #6 irasabwa mu bihe byo kwangirika kw'imodoka n'ubushyuhe bwinshi ndetse n'aho ingese iterwa n'ingufu, cyangwa byombi. Bimwe mu bikorwa bisanzwe ni valve z'imodoka n'iz'amazi, chain saw guides, hot punches, shear blades, na extruder vis.

Cobalt 12
Elektrode na EcoCr-B electrode na rod zisa mu buryo busa n'ibice byakozwe hakoreshejwe ECoCr-A (Cobalt 6) electrode na rod, usibye ijanisha riri hejuru gato (hafi 16%) rya karubide. Ifumbire ifite kandi ubukana buri hejuru gato kandi irwanya kwangirika no kwangirika neza hagati y’icyuma n’icyuma. Kurwanya kwangirika no kwangirika biragabanuka gato. Ibice byakagombye gucukurwa hakoreshejwe ibikoresho bya karubide.
Elektrode za ECoCr-B (Cobalt 12) zikoreshwa mu buryo bumwe na ECoCr-A (Cobalt 6). Amahitamo azaterwa n'ikoreshwa ryihariye.

Cobalt 1
ECoCr-C ifite igipimo kiri hejuru (hafi 19%) cya karubide ugereranyije n'ibicuruzwa byakozwe hakoreshejwe ECoCr-A (Cobalt 6) cyangwa ECoCr-B (Cobalt 12). Mu by'ukuri, imiterere yayo ni uko karubide z'ibanze ziboneka mu miterere mito. Iyi miterere ituma karubide irushaho kwangirika hamwe no kugabanuka kw'ingaruka no kudakomera. Ubukana bwinshi bunasobanura ko ubushake bunini bushobora kugabanuka binyuze mu gukurikirana neza uburyo bwo gushyushya mbere, ubushyuhe bwo hagati, n'uburyo bwo gushyushya nyuma yo gushyushya.
Nubwo imiterere ya cobalt-chromium yoroha gato iyo ubushyuhe buri hejuru, ubusanzwe ifatwa nk'idahinduka. Electrode za ECoCr-C zikoreshwa mu kubaka ibintu nk'ibivangavanga, rotors cyangwa aho hose hagaragaye ubukana bukomeye n'ingaruka nke.

Cobalt 21
Elektrode za ECoCr-E zifite imbaraga n'ubushobozi bwo kugenda neza cyane mu bushyuhe bugera kuri 1600°F (871°C). Ibice byazo birwanya ubushyuhe, ogisijeni, no kugabanya ikirere. Ikoreshwa rya mbere ry'ubu bwoko bw'ibyuma byabonetse mu bice bya moteri ya jet nka turbine blades na vanes.
Iyi aloyi ni aloyi ikomeye kandi igororotse ifite uburemere buke bwa karubide mu miterere yayo. Bityo, iyo aloyi ni ikomeye cyane kandi izakora neza. Iyo aloyi ifite ubushobozi bwo guhangana n'ubushyuhe kandi irwanya cyane isuri.
Elektrode za ECoCr-E zikoreshwa aho kurwanya ubushyuhe ari ingenzi. Ikoreshwa risanzwe; nk'iry'ibice byakoreshejwe hakoreshejwe Elektrode za ECoCr-A (Cobalt 6); imigozi y'ubuyobozi, imashini zishyushye zo gusohora no gucura, ibyuma bishyushye byo gukata, uduce tw'icyuma, n'udupira tw'amashanyarazi.
