Ibicuruzwa byacu
Gusya Impeta
Ibyiza bya tekiniki
Kurwanya kwambara ibikoresho byurusyo ni ngombwa.Mubisanzwe, abantu benshi batekereza ko uko ibicuruzwa bigoye, niko birushaho kwambara, kubwibyo, ibigo byinshi byamamaza ko casting zabo zirimo chromium, amafaranga agera kuri 30%, naho ubukana bwa HRC bugera kuri 63-65.Nyamara, uko gutatanya gukwirakwizwa, niko bishoboka cyane ko habaho micro-umwobo na micro-crack kuri interineti hagati ya matrix na karbide, kandi amahirwe yo kuvunika nayo azaba manini.Kandi nikintu gikomeye, nikintu gikomeye.Kubwibyo, gukora impeta idashobora kwihanganira kandi biramba gusya ntabwo byoroshye.Gusya impeta ukoresheje ubwoko bubiri bwibikoresho bikurikira.
65Mn (65 manganese): ibi bikoresho birashobora kuzamura cyane kuramba kwimpeta.Ifite ibiranga ubukana bwinshi, kwihanganira kwambara neza no kurwanya magnetisme nziza, ikoreshwa cyane mumurima utunganya ifu aho ibicuruzwa bigomba gukuramo ibyuma.Kurwanya kwambara no gukomera birashobora kunozwa cyane muguhindura ubushyuhe no kugabanya ubushyuhe.
Mn13 (13 manganese): igihe kirekire cyo gusya impeta yo gusya hamwe na Mn13 cyatejwe imbere ugereranije na 65Mn.Gutera iki gicuruzwa bivurwa no gukomera kwamazi nyuma yo gusuka, guterana bifite imbaraga zingana, gukomera, plastike hamwe nuburyo butari magnetique nyuma yo gukomera kwamazi, bigatuma impeta yo gusya iramba.Iyo bikorewe ingaruka zikomeye hamwe no guhindagurika gukomeye mugihe cyo kwiruka, ubuso buzakorwa nakazi gakomeye kandi bugire martensite, bityo bigire urwego rwo hejuru rwihanganira kwambara, urwego rwimbere rugumana ubukana buhebuje, kabone niyo rwaba rwambarwa hejuru cyane, gusya uruziga rushobora kwihanganira imitwaro myinshi.
