Hariho ibyiciro bitatu byo gupima ibipimo bikomeye byitanura, aribyo bikabije, Rockwell no hejuru ya Rockwell Gukomera Indangagaciro. Dukurikije uburyo bwo kuvura ubushyuhe, uburyo bwo kwipimisha bukomeye bwo kuzimya hejuru no gukaranga igihanga cyo kuvura ubushyuhe hamwe nigitanda cya chimique gitandukanye nacyo.
Ibipimo nyamukuru bya tekiniki byabakozi bashinzwe kuvura imiti byinangiye ubujyakuzimu no gukomera hejuru. Ubujyakuzimu bukomeye bugomba kugeragezwa hamwe na vickers gukomera. Gerageza intera kuva kumurimo ukorera hejuru kugeza aho hatonyanga hatonyanga 50hrc. Ubu ni ubujyakuzimu bukomeye.
Guvura ubushyuhe bwa chimique ni ugutwara hejuru yumurimo hamwe na atome yibintu bimwe cyangwa byinshi, bityo bihindura imiti, imiterere numutungo wubuso bwakazi. Nyuma yo kumara kandi hasi - ubushyuhe bubabaza, ubuso bwakazi bufite ubukana, bambara imbaraga no kuvugana na faruguece, mugihe ishingiro ryumunani rifite ubunini.
Ikizamini cyo hejuru cyo gukomera kumurimo wimikorere yumubiri wamatanura imiti yimiti irasa nubushakashatsi bukomeye bwumukozi ucuruza ubushyuhe. Byombi birashobora kugeragezwa na vickers gukomera tester, hejuru ya rockwell gukomera tester cyangwa rockwell gukomera. Ariko, ubunini bwikibyimba nitrid nibworoshye, muri rusange ntabwo birenga 0.7mm, nuko rero Urutare rwagati ntigikoreshwa.
Niba ibisabwa muriho bisabwa nibice ni byinshi, byaho bigabanya ubushyuhe bushobora gukorwa no kwishyuza hamwe nubundi buryo. Ibice nkibi mubisanzwe bikeneye kuranga aho hamwe nubushobozi bukomeye bwaho bwimiterere yaho igabanya ubushyuhe ku gishushanyo. Ikigeragezo gikomeye cyibice bigomba gukorwa mukarere kagenwe. Igikoresho cyo kwipimisha kitoroshye gishobora gukoresha gukomera gukomeye tester kugirango ugerageze agaciro ka HRC. Niba kuvura ubushyuhe birushijeho kurengana ni bike, hejuru ya rockwell gukomera tester irashobora gukoreshwa mugupima agaciro ka hrn.
Ubuso bwo kwizirika no gukesha ubushyuhe bwitanura ryibiti mubisanzwe bikorwa no kwishyuza cyangwa gushyushya. Ibipimo nyamukuru bya tekiniki ni ugukomera, gukomera kwaho hamwe nubujyakuzimu bukomeye. Ikizamini gikomeye gishobora gukorwa na vickers gukomeza tester, rockwell cyangwa hejuru ya rockwell gukomera. Guhitamo imbaraga zibizamini (igipimo) bifitanye isano nubujyakuzimu bukomeye hamwe nubuso bwubuso bwakazi. Hariho ubwoko butatu bwo gufata ibyemezo binini.
Abashutse Hardness Tester nuburyo bwingenzi bwo kugerageza ubushyuhe bwubushyuhe - abakozi bafashwe bafashwe. Irashobora gukoresha imbaraga za 0.5 kugeza 100 kanda hejuru yubuso bunini cyane nka mm 0.05. Ifite ukuri kwisumbuye kandi irashobora gutandukanya ikintu gito mubuso bwakazi. Byongeye kandi, ubujyakuzimu bukomeye urwego rugomba kandi gukurwa nabasuka gukomera. Kubwibyo, birakenewe guha ibikoresho bya vicline gukomera kubice bikora ubushyuhe bwo hejuru cyangwa bugakoresha umubare munini wubushyuhe {{8} abakozi bafashwe bafashwe.
Ubuso bwa rockwell gukomera tester nanone birakwiriye cyane kugerageza gukomera kwakazi. Hejuru ya rockwell gukomera tester ifite umunzani itatu kugirango uhitemo. Irashobora kugerageza ibintu bitandukanye bigoramye hamwe nimbaraga nziza zirenga 0.1 mm. Nubwo ari ukuri kwukuri gukomera testerne ntabwo ari hejuru nkibya vickers bikomeye, birashobora kubahiriza ibisabwa nkubuyobozi bwujuje ubuziranenge bwibihingwa bivura ubushyuhe. Byongeye kandi, ifite ibiranga imikorere yoroshye, ikoreshwa ryoroshye, igiciro gito, gupima vuba, no gusoma neza agaciro. Ubuso bwa rockwell gukomera tester birashobora gukoreshwa vuba kandi atari -} isengeramo ibizamini byubuso bwubutaka -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} س Ibi bifite akamaro gakomeye kumikorere yicyuma no gutunganya imashini.
Iyo ubushyuhe bukabije bwo kuvura urwego rwitanura ryimyobo nibyimbye, Rockwell Ikizamini cyo gukomeretsa nacyo. Iyo ubunini bukomeye bunini ari 0.4-0.8mm, igipimo cya HRA kirashobora gukoreshwa, kandi mugihe ubunini bukomeye burenze 0.8mm, igipimo cya HRC gishobora gukoreshwa.
Indangagaciro eshatu zikomeye za vickers, Rockwell na Shotwell irashobora guhinduka byoroshye kandi ihinduka agaciro gakomeye isabwa nibipimo, ibishushanyo cyangwa abakoresha. Imbonerahamwe ijyanye no guhinduka itangwa mumahanga mpuzamahanga iso, Astm y'Abanyamerika n'Igishinwa gisanzwe GB / T.
