Byakoreshejwe cyane mu musaruro ni ugukomera kwuburyo bwamakuru, nka brunell hardness, gukomera gukomera, gukomera no gukomera no gukomera. Abafite ubukana bwabonetse mubyukuri byerekana imyigaragambyo yubutaka kugeza kuri plastike biterwa no kwinjira mubintu byamahanga.
Ibikurikira ni intangiriro ngufi mubice bitandukanye bikomeye:
1. Brinell Hardness (HB)
Kanda umupira ukomeye wubunini bumwe (mubisanzwe 10mm muri diameter) hejuru yibikoresho hamwe numutwaro runaka (muri rusange 3000kg) hanyuma ubikomeze mugihe runaka. Umutwaro umaze gukurwaho, igipimo cyumutwaro ahantu ho kugana ni agaciro ka Brinell (HB), kurupapuro rwa Kilo / MM2 (n / mm2).
2. Gukomera gukomera (HR)
Iyo HB> 450 cyangwa icyitegererezo ni gito cyane, Ikizamini gikomeye cya Brinell ntigishobora gukoreshwa no gupima gupima gukomeye bigomba gukoreshwa aho. Ikoresha Diamond Cone hamwe na Vortex inguni ya 120 ° cyangwa umupira wicyuma hamwe na diameter ya 1.59mm na 3.18m kugirango uhagarike hejuru yibikoresho, kandi gukomera kw'ibikoresho biboneka ku myambarire. Ukurikije ubukana bwibikoresho byikizamini, birashobora kugaragarira muminzani itatu itandukanye:
HRA: Birakomeye byabonetse ukoresheje umutwaro wa 60kg hamwe na diyama ya diyama, kandi ikoreshwa mubikoresho bifite ubukana buhebuje (nko guhambira karbite, nibindi).
HRB: Nugukomera byabonetse ukoresheje umutwaro wa 100kg numuraba unangiye ufite diameter ya 1.58mm. Ikoreshwa kubikoresho hamwe no gukomera hasi (nko kubyuma bishaje, bitera icyuma, nibindi).
HRC: Ni ngombwa ko uboneka ukoresheje umutwaro wa 150kg hamwe na Diamond Cone itangwamo, kandi ikoreshwa mubikoresho hamwe no gukomera kwinshi (nka steel ikomeye, nibindi).
3 ba dickers ubukana (hv)
Koresha Ikibanza cya Diamond COne hamwe numutwaro uri munsi ya 120kg na vertex ya 136 kugirango ukande ahantu h'ibikoresho, hanyuma ukagabanya ahantu h'ibikoresho by'umutwaro ku buryo bwa Agaciro HV (KGF / MM2).
Ugereranije na bristell kandi yuzuye ibizamini bikomeye, ibizamini bikomeye bipima bifite ibyiza byinshi. Ntabwo ifite inzitizi yibintu byagenwe byerekana p na indenter diameter d kimwe na brinell, nikibazo cyo guhindura itarondoguriwe; Nta nubwo ufite ikibazo ko agaciro ka Rocwell kidashobora guhuzwa. Kandi irashobora kugerageza ibikoresho byoroshye kandi bikomeye nka rock, kandi birashobora kugerageza ubukana bwibice bitoroshye (cyangwa ibice bito) biruta rocwell, bishobora gukorwa gusa na rockwell hejuru. Ariko nubwo mubihe nkibi, birashobora kugereranwa gusa nigipimo cya rockwell, kandi ntigishobora guhuza izindi nzego zikomeye. Byongeye kandi, kubera ko Rockwell ikoresha indentation yimbitse nkigipimo cyo gupima, kandi ubujyakuzimu bwa indentation buri gihe ni gito kuruta ubugari bwa indentation, bityo ikosa ryayo naryo rinini. Kubwibyo, amakuru akomeye ya rockswell ntabwo ahamye nka Brinell na Vickers, kandi birumvikana ko bidahagaze nkabashitsi.
Hariho umubano wo guhinduka hagati ya brunell, urutare na vickers, kandi hariho ameza yumubano wo guhindura ashobora kubazwa.
