Igipimo gikomeye cya Rockwell cyavumbuwe na Stanley Rockwell mu 1919 kugirango gisuzume vuba ubukana bwibikoresho byicyuma.
(1) HRA
Method Uburyo bwikizamini nihame: · Ikizamini gikomeye cya HRA gikoresha indimu ya diyama kugirango ikande hejuru yibintu munsi yumutwaro wa kg 60, kandi igena agaciro k’ibikoresho mu gupima ubujyakuzimu. Type Ubwoko bwibikoresho bikoreshwa: · Ahanini bikwiranye nibikoresho bikomeye cyane nka karbide ya sima, ceramika nicyuma gikomeye, hamwe no gupima ubukana bwibikoresho byoroshye kandi bipfutse. Ibisanzwe bikoreshwa: · Gukora no kugenzura ibikoresho nububiko. · Kugerageza gukomera ibikoresho byo gukata. · Kugenzura ubuziranenge bwo gutwikira hamwe nibikoresho byoroshye. Ibiranga ibyiza: · Gupima byihuse: Ikizamini cya HRA gishobora kubona ibisubizo mugihe gito kandi kirakwiriye kumenyekana byihuse kumurongo wibyakozwe. · Ubusobanuro buhanitse: Bitewe no gukoresha indimu ya diyama, ibisubizo byikizamini bifite isubiramo ryinshi kandi ryukuri. · Guhinduranya: Ashoboye kugerageza ibikoresho byuburyo butandukanye, harimo amasahani mato hamwe na kote. . Icyitonderwa cyangwa imbogamizi: · Gutegura icyitegererezo: Ubuso bw'icyitegererezo bugomba kuba buringaniye kandi busukuye kugirango harebwe ibisubizo by'ibipimo. · Kubuza ibikoresho: Ntibikwiye kubikoresho byoroshye cyane kuko indenter irashobora gukanda hejuru yicyitegererezo, bikavamo ibisubizo byo gupima bidakwiye. Kubungabunga ibikoresho: Ibikoresho byipimisha bigomba guhindurwa no kubungabungwa buri gihe kugirango ibipimo bipime neza kandi bihamye.
(2) HRB
Method Uburyo bwikizamini nihame: · Ikizamini gikomeye cya HRB gikoresha icyuma cyumupira wa 1/16 cya santimetero kugirango ukande hejuru yumutwaro munsi yumutwaro wa kg 100, kandi agaciro k’ibikoresho kugenwa no gupima ubujyakuzimu. Type Ubwoko bwibikoresho bikoreshwa: · Bikoreshwa mubikoresho bifite ubukana buciriritse, nk'umuringa wumuringa, aluminiyumu ya aluminiyumu nicyuma cyoroheje, kimwe nibyuma byoroshye nibikoresho bitari ibyuma. Applices Ibisanzwe bikoreshwa: · Kugenzura ubuziranenge bw'amabati n'imiyoboro. · Kugerageza gukomera kwibyuma bidafite fer na alloys. · Kwipimisha ibikoresho mubikorwa byubwubatsi n’imodoka. Ibiranga ibyiza: · Ikizamini cyoroshye: Inzira yikizamini iroroshye kandi yihuse, ibereye kwipimisha byihuse kumurongo wibyakozwe. · Ibisubizo bihamye: Bitewe no gukoresha umupira wibyuma, ibisubizo byikizamini bifite umutekano uhamye kandi bisubirwamo. . Icyitonderwa cyangwa imbogamizi: · Gutegura icyitegererezo: Ubuso bwikitegererezo bugomba kuba bworoshye kandi buringaniye kugirango hamenyekane neza ibisubizo byapimwe. · Kugabanya imipaka igoye: Ntabwo ikoreshwa mubikoresho bikomeye cyangwa byoroshye cyane, kubera ko indenter idashobora gupima neza ubukana bwibi bikoresho. · Kubungabunga ibikoresho: Ibikoresho byikizamini bigomba guhindurwa no kubungabungwa buri gihe kugirango harebwe niba ibipimo bifatika.
(3) HRC
Method Uburyo bwikizamini nihame: · Ikizamini gikomeye cya HRC gikoresha indimu ya diyama kugirango ikande hejuru yibintu munsi yumutwaro wa kg 150, kandi agaciro k’ibikoresho kugenwa no gupima ubujyakuzimu. Types Ubwoko bwibikoresho bikoreshwa: · Ahanini bikwiranye nibikoresho bikomeye, nkibyuma bikomeye, karbide ya sima, ibyuma byabikoresho nibindi bikoresho bikomeye cyane. Porogaramu isanzwe ikoreshwa: · Gukora no kugenzura ubuziranenge bwibikoresho byo gutema. · Kugerageza gukomera kwicyuma gikomeye. · Kugenzura ibikoresho, ibyuma nibindi bikoresho bikomeye byo gukanika. ④ Ibiranga ibyiza: · Ibipimo byihuse: Ibisubizo by'ibizamini birashobora kuboneka mugihe gito, bikwiriye kugenzurwa byihuse kumurongo wibyakozwe. · Porogaramu yagutse: Irakoreshwa mugupima ibikoresho bitandukanye bikomereye cyane, cyane cyane ibyuma bikoreshwa nubushyuhe hamwe nicyuma cyibikoresho. Es Icyitonderwa cyangwa imbogamizi: · Gutegura icyitegererezo: Ubuso bw'icyitegererezo bugomba kuba buringaniye kandi busukuye kugirango harebwe ibisubizo by'ibipimo. Imipaka ntarengwa: Ntibikwiye kubikoresho byoroshye cyane, kuko cone ya diyama irashobora gukanda cyane murugero, bikavamo ibisubizo byo gupima bidakwiye. Kubungabunga ibikoresho: Ibikoresho byipimisha bisaba kalibrasi isanzwe no kuyitaho kugirango harebwe niba ibipimo bifatika.
(4) HRD
Method Uburyo bwikizamini nihame: · Ikizamini gikomeye cya HRD gikoresha indimu ya diyama kugirango ikande hejuru yumutwaro munsi yumutwaro wa kg 100, kandi agaciro k’ibikoresho kugenwa no gupima ubujyakuzimu. Type Ubwoko bwibikoresho bikoreshwa: · Ahanini bikwiranye nibikoresho bifite ubukana burenze ariko munsi yurwego rwa HRC, nkibyuma bimwe na bimwe bikomeye. Appar Ibisanzwe bikoreshwa: · Kugenzura ubuziranenge no kugerageza ibyuma. · Kugerageza ubukana bwikigereranyo cyo hagati kugeza hejuru. Kugerageza ibikoresho no kubumba, cyane cyane kubikoresho bifite urwego ruciriritse rukomeye. Ibiranga ibyiza: · Gusubiramo cyane: Indente ya diamant itanga ibisubizo bihamye kandi bisubirwamo cyane. · Porogaramu yoroheje: Irakoreshwa mugupima ubukana bwibikoresho bitandukanye, cyane cyane hagati ya HRA na HRC. . Icyitonderwa cyangwa imbogamizi: · Gutegura icyitegererezo: Ubuso bw'icyitegererezo bugomba kuba buringaniye kandi busukuye kugirango harebwe ibisubizo by'ibipimo. Imipaka ntarengwa: Kubikoresho bikomeye cyangwa byoroshye, HRD ntishobora kuba amahitamo akwiye. Kubungabunga ibikoresho: Ibikoresho byipimisha bisaba kalibrasi isanzwe no kuyitaho kugirango ibipime neza kandi byizewe.
