Impeta yo gusya ku cyuma

Ubudahangarwa bw'ibikoresho by'inganda ni ingenzi. Muri rusange, abantu benshi babona ko uko ibicuruzwa bikomeye, ari nako byoroshye kwambara, bityo, inganda nyinshi zikora uruganda zitangaza ko ibikoresho byazo birimo chromium, ingano igera kuri 30%, naho ubukana bwa HRC bugera kuri 63-65. Ariko, uko ikwirakwizwa ry'ibikoresho rikwirakwira cyane, ni ko amahirwe yo gukora utwobo duto n'uduce duto ku gice kiri hagati ya matrix na carbides aba menshi, kandi amahirwe yo kuvunika azaba menshi. Kandi uko ikintu gikomeye, ni ko bigorana gukata. Kubwibyo, gukora impeta yo gusya idashira kandi iramba ntabwo byoroshye. Gusya impeta ahanini hakoreshejwe ubwoko bubiri bw'ibikoresho bikurikira.

65Mn (65 manganese): iyi mashini ishobora kongera cyane uburambe bw'impeta isya. Ifite imiterere yo gukomera cyane, idapfa kwangirika neza kandi irwanya ingufu za rukuruzi, ikoreshwa cyane cyane mu ifu itunganywa aho icyuma gikenera gukuraho icyuma. Ubudapfa kwangirika no gukomera bishobora kongerwa cyane binyuze mu kuvugurura no gushyushya ubushyuhe.

Mn13 (13 manganese): gukomera kw'imashini isya impeta ikoresheje Mn13 kwarushijeho kuba kwiza ugereranije na Mn 65. Imashini isya iyi mashini ivurwa n'ubukana bw'amazi nyuma yo gusukwa, imashini isya ifite imbaraga zo gukurura, ubukana, ubuziranenge n'ubushobozi butari ubw'ingufu nyuma yo gukomereka kw'amazi, bigatuma imashini isya ikomera. Iyo ihuye n'ingaruka zikomeye n'ihindagurika rikomeye ry'umuvuduko mu gihe cyo kuyikoresha, ubuso buzakomera kandi bugahinduka martensite, bityo bugakora urwego rw'ubuso rudashira cyane, urwego rw'imbere rugumana ubukana bwiza cyane, nubwo rwambarwa ku buso buto cyane, imashini isya ishobora kwihanganira imitwaro myinshi.
