Ni gute ingano ya Cr na C igira ingaruka ku kudashira kw'amasahani adashira?

Karuboni ni cyo kintu cy'ingenzi mu gukora karuboni. Iyo Cr ihari, karuboni ihuzwa na chromium igakora karuboni (Cr₇C₃, Cr₃C₂, nibindi). Uko karuboni iba nyinshi, niko karuboni iba nyinshi, bityo bikanongera ubukana bw'ibikoresho no kudashira.

Chromium ni ingenzi mu gukora carbides zikomeye zihamye, kandi ifite ubushobozi bwo kudahinduka mu bushyuhe bwinshi no kurwanya ogisijeni. Muri sisitemu ya Cr nyinshi, kristu za chromium carbide zikura mu buryo bugororotse kandi zigashyirwa ku murongo ugororotse ugana ku cyerekezo cyo kwangirika, bifasha kurwanya gushwanyagurika no kwangirika. Byongeye kandi, Cr ishobora kandi kugira uruhare mu gutunganya ibinyampeke mu gusuka no kunoza ubucucike bw'ikigo.

Mu gishushanyo, ubusanzwe ingano ya Cr igenzurwa kuri 18% ~ 30%, naho ingano ya C iri hagati ya 3% ~ 5%. Iki gipimo gishobora gukora umubare munini wa karubide zo mu bwoko bwa Cr₇C₃ zikwirakwizwa ku buryo bungana zifite ubukana bwinshi n'ubushobozi buke bwo gukururana, bigatuma ubuzima bw'ibikoresho burushaho kuba bwiza mu gihe cy'umuvuduko mwinshi n'ingaruka nyinshi.
