Ku muntu utamenyereye, icyuma gizunguruka gishobora kumera nk'icyuma cyoroshye. Ariko, imikorere yacyo ni umusaruro utaziguye w'ubumenyi bw'ibikoresho buhambaye. Ijambo "tungsten carbide" ubwaryo ryerekeza ku bikoresho bivanze, cermet, aho uduce twa tungsten carbide dukomeye cyane duhuzwa hamwe n'icyuma gifunga icyuma, akenshi cobalt. Ingano yihariye, nka YG8, niyo resept y'ibanga igena imikorere y'igikoresho.
YG8 igaragaza imiterere ya karubine ya tungsten 92% na kobalti 8% ukurikije uburemere. Iki gipimo ntabwo ari ikintu gishingiye ku bipimo. Karubine ya tungsten itanga ubukana bukabije—akenshi bupima hafi 90 HRA ku gipimo cya Rockwell—ibi bikaba ari ingenzi mu gukura no gukata ibindi bikoresho bikomeye. Ubu bukana ni bwo butuma umuntuagace k'inyandiko ka carbide burr gakora nezagusya icyuma kidashonga neza no gusya icyuma gishongeshejwe bidahita bihinduka umubyimba.
Ariko, gukomera byonyine ntibihagije. Igikoresho gikomeye cyane gishobora kwangirika no gucika intege cyangwa kwangirika bikomeye bitewe n'igitutu cyo ku ruhande rw'icyuma gisya. Aha niho cobalt ifata. Cobalt yongera imbaraga n'ubudahangarwa, bigatuma umutwe w'icyuma gisya winjira mu ngaruka n'imitingito y'imikorere y'icyuma udacitse. 8% bya cobalt muri YG8 ni uburyo bwiza bwagenewe kuringaniza neza; butanga ubudahangarwa bwiza bwo kwangirika (nubwo buri munsi gato ya cobalt yo hasi nka YG6) mu gihe butanga imbaraga n'ubudahangarwa bwiza cyane, bigatuma kiba cyiza cyane.
Iyi miterere y'umutungo iringaniye ni yo mpamvu icyuma cya YG8 tungstenumutwe wo gusyaishobora kuvuga ko ifite ubushobozi bwinshi cyane. Biragoye bihagije guhangana n'ihungabana riterwa no gukora ku byuma bishongeshejwe cyangwa ahantu hatangana. Muri icyo gihe, biragoye cyane gukomeza gukoresha uburyo buhanitse mu gihe kirekire hakoreshejwe ibikoresho bisya nk'icyuma kidashonga, bigakora cyane mu gihe cyo gukora.
Gusobanukirwa ubu bumenyi bifasha abakoresha guhitamo igikoresho gikwiye akazi. Kugira ngo hakorwe neza ibikoresho bimwe aho ubushobozi bwo kwangirika bugarukira cyane, hashobora gutorwa urwego rwo hasi rwa cobalt. Ariko ku bwinshi bw'ibikorwa rusange, harimo no gutunganya icyuma, icyuma, umuringa, na aluminiyumu, YG8 ihagarariye urugero rwa zahabu rw'imikorere no kuramba. Ni ubu buryo bushya bwo guhindura igikoresho cyoroshye mo igikoresho gikwiye gukora ibintu byose kuva ku bukorikori bw'inganda kugeza ku gushushanya amabuye n'amagufwa neza.
Incamake y'ibicuruzwa: Irebere uburyo butunganye bwo gukomera no gukomera hamwe n'ibyuma byacu bizunguruka, bikozwe mu cyuma cya YG8 tungsten. Iyi dosiye izunguruka ishobora gutunganya icyuma, icyuma gishongeshejwe, icyuma gitanga umuvuduko mwinshi, icyuma cya alloy, icyuma kitagira umuvuduko, umuringa, aluminiyumu, ndetse n'ibindi bitari ibyuma nka marble, jade, na foromaje.
