Igice cya diyama numubiri ukora wa diyama wabonye icyuma. Umutwe ukata diyama wabonye icyuma kigizwe na diyama na matrix binder. Diamond ni ibikoresho bihebuje bikora nkibice. Matrix binder ifite uruhare rwo gutunganya diyama. Igizwe nifu yicyuma cyoroshye cyangwa ifu ya alloy powder Ifumbire, ibihimbano bitandukanye byitwa formula, naho formula zitandukanye na diyama ukurikije imikoreshereze itandukanye.

1. Guhitamo ingano ya diyama

Iyo ingano ya diyama ari ntoya kandi ifite ubunini bumwe, umutwe wicyuma urakara kandi imikorere yo kubona irakabije, ariko imbaraga zo kugonda za diyama zigabanuka; iyo ingano ya diyama ari nziza cyangwa ingano nini nini nini ivanze, umutwe wicyuma uba ufite igihe kirekire, ariko ntigikora neza. Urebye ibintu byavuzwe haruguru, birakwiye cyane guhitamo ingano ya diyama ingana na 50/60 mesh.

2. Guhitamo gukwirakwiza diyama

Mu ntera runaka, iyo intumbero ya diyama ihindutse kuva hasi kugeza hejuru, ubukana no kugabanya imikorere yicyuma bizagenda bigabanuka buhoro buhoro, mugihe ubuzima bwa serivisi buzagenda bwiyongera buhoro buhoro; ariko niba kwibumbira hamwe ari byinshi, icyuma kibonye kizahinduka. Kandi gukoresha imikoreshereze mike, ingano ntoya, imikorere izanozwa. Gukoresha imirimo itandukanye ya buri gice cyumutwe wumutwe mugihe cyo kubona, hakoreshwa ibitekerezo bitandukanye (nukuvuga, intumbero yo hasi irashobora gukoreshwa murwego rwo hagati murwego rwibice bitatu cyangwa byinshi byubatswe), hanyuma hagashyirwaho igikoni cyo hagati gukata umutwe mugihe cyo kubona, bifite ingaruka runaka. Nibyiza gukumira icyuma kibisi kidahinduka, bityo bikazamura ubwiza bwo gutunganya amabuye.

3. Guhitamo imbaraga za diyama

Imbaraga za diyama nikimenyetso cyingenzi kugirango igabanye imikorere. Imbaraga nyinshi cyane zizatuma kristu itoroha kumeneka, ibinyampeke byangiza bizahanagurwa mugihe cyo gukoresha, kandi ubukana buzagabanuka, bivamo kwangirika kwimikorere yibikoresho; iyo imbaraga za diyama zidahagije, izavunika byoroshye nyuma yo gukorerwa, kandi biragoye kwikorera inshingano zikomeye zo gutema. Kubwibyo, imbaraga zigomba gutoranywa kuri 130-140N

4. Guhitamo icyiciro cya binder

Imikorere yicyuma ntigishobora guterwa na diyama gusa, ahubwo nigikorwa rusange cyibikoresho bigize diyama yibiti hamwe numutwe wogukata byakozwe nubufatanye bukwiye bwa binder. Kubikoresho byoroshye byamabuye nka marble, imiterere yubukanishi bwumutwe ukata irasabwa kuba muke, kandi imiringoti ishingiye kumuringa irashobora gukoreshwa. Nyamara, ubushyuhe bwa sinteri yumuringa ushingiye kumuringa ni muke, imbaraga nubukomere biri hasi, ubukana buri hejuru, kandi imbaraga zo guhuza na diyama ni nke. Iyo karubide ya tungsten (WC) yongeyeho, WC cyangwa W2C ikoreshwa nkicyuma cya skeleton, hamwe na cobalt ikwiye kugirango itezimbere imbaraga, ubukana nibiranga isano, hamwe na Cu, Sn, Zn nibindi byuma bifite bike gushonga ingingo hamwe nubukomezi buke byongeweho guhuza Mugenzi. Ingano yubunini bwibintu byingenzi igomba kuba nziza kurenza mesh 200, naho ingano yingingo yongeweho igomba kuba nziza kuruta mesh 300

5. Guhitamo inzira yo gucumura

Mugihe ubushyuhe bwiyongereye, urwego rwo kwiyegereza umurambo rwiyongera, kandi imbaraga za flexural nazo ziriyongera, kandi hamwe no kwagura igihe cyo gufata, imbaraga zihindagurika zintumbi zambaye ubusa na agglomerate ya diyama zabanje kwiyongera hanyuma zikagabanuka. Gucumita kuri 800 ° C kuri 120 kugirango wuzuze ibisabwa.
