Nkumuntu uhagarariye karbide ikunze gukoreshwa cyane, tungsten cobalt ciment cbide (YG ubwoko bwa karbide ya sima) bivuga amavuta agizwe na karubide ya tungsten nkicyiciro gikomeye na cobalt nkicyiciro cya sima, izina ryicyongereza ni tungsten cobalt ciment cbide, kandi, izina ryikirango rigizwe na YG hamwe nijanisha ryibipimo bya cobalt.Izina ryikirango rigizwe na "YG" nijanisha ryibintu bisanzwe bya cobalt, nka YG6, YG8 nibindi.
Ku bijyanye n’imikorere, YG yashimangiye karbide ikomatanya ibyiza bya karubide ya tungsten na cobalt, bigaragarira cyane cyane mubukomere bukabije, imiyoboro myiza yumuriro, gukomera kwingaruka nziza, imbaraga zo guhindagurika no kurwanya gukata neza.Ariko, twakagombye kumenya ko ibipimo bifatika byibyiciro bitandukanye bya YG sima ya karbide bitandukanye, nkubucucike bwa YG6 ni 14,6 ~ 15.0g / cm3, ubukana 89.5HRA, imbaraga zidasanzwe 1400MPa, ubukana bwingaruka 2.6J / cm2, guhatira 9.6 ~ 12.8KA / m, imbaraga zo kwikuramo 4600MPa;ubucucike bwa YG8 ni 14.5 ~ 14.9g / cm3;ubucucike bwa YG8 ni 14.5 ~ 14.9g / cm3;n'ubucucike bwa YG8 ni 14.5 ~ 14.9g / cm3.YG8 ifite ubucucike bwa 14.5 ~ 14.9g / cm3, ubukana bwa 89HRA, imbaraga zidasanzwe za 1500MPa, ubukana bwingaruka bwa 2.5J / cm2, agahato ka 11.2 ~ 12.8KA / m, nimbaraga zo kwikuramo 4600MPa.Muri rusange, hamwe no kwiyongera kwa cobalt muburyo runaka, imbaraga za alloy's flexural and compressive imbaraga hamwe no gukomera nibyiza, mugihe ubucucike nubukomezi biri hasi.
Kurwanya kwambara no gukomera byubwoko bwa YG bwa sima ya karbide mubisanzwe ni imibiri ivuguruzanya, igaragara cyane muri ibi bikurikira: mubihe bimwe na bimwe, hamwe no kwiyongera kwa cobalt cyangwa kugabanuka kwibintu bya tungsten, ubukana bwumuti ni byiza kandi birwanya kwambara birakennye;muburyo bunyuranye, hamwe no kwiyongera kwa tungsten cyangwa kugabanuka kwibintu bya cobalt, imitungo yangiza ya alloy ni nziza kandi gukomera ni bibi.Mu rwego rwo gukemura ikibazo cyo guhangana n’imyenda itavuguruzanya no gukomera kwa karubide yo mu bwoko bwa YG ya sima, umushakashatsi wa Patent No CN1234894C atanga uburyo bushya bwo kubyaza umusaruro, ibyiza by’ikoranabuhanga ribyara umusaruro ni: 1) Kubera imiterere idahuje Ibinyampeke bya WC, imitunganyirize ya karbide ya sima iratera imbere (WC yegeranye n’ingano iragabanuka, Co icyiciro cyo gukwirakwiza ni kimwe, porotike iragabanuka, kandi inkomoko iragabanuka cyane), bityo rero kwihanganira kwambara no gukomera byuruvange ni byiza kuruta ibyo kimwe cobalt coarser-ibinyamisogwe;2) Gukoresha ifu nziza ya cobalt nibyiza kuruta gukoresha ifu ya cobalt isanzwe (2-3μm), kandi ubukana bwiyi mavuta bwongerwaho 5 kugeza 10%, mugihe hiyongereyeho (0.3-0.6wt%) TaC yiyongera ubukana bwayo (HRA) kuri 0.2 kugeza 0.3, ni ukuvuga ko kwambara kwayo nabyo byongerewe.~ 10%, kandi nyuma yo kongeramo (0.3-0.6wt%) TaC, ubukana bwayo (HRA) bwiyongereyeho 0.2-0.3, ni ukuvuga ko imyambarire yayo nayo yiyongera.
Ukurikije ubwoko bwubwoko, ukurikije ibirimo bitandukanye bya cobalt, karbide ya tungsten-cobalt isima karbide irashobora kugabanywamo cobalt nkeya, cobalt yo hagati na cobalt nyinshi;ukurikije ibinyampeke bitandukanye bya tungsten karbide, irashobora kugabanywamo ingano nto, ingano nziza, ingano yo hagati hamwe nimbuto zoroshye;ukurikije imikoreshereze itandukanye, irashobora kugabanywamo ibikoresho byo gutema, ibikoresho byo gucukura amabuye y'agaciro n'ibikoresho bidashobora kwambara.
Urebye uburyo bwo kubyaza umusaruro, intambwe zo gutegura karubide YG ya sima zirimo ifu ya karubide ya tungsten hamwe nifu ya cobalt binyuze mu gukata, gusya neza, kumisha, guhunika, gukanda no gukora, gukora de-form, gucumura nibindi.Icyitonderwa: Ubwoko bubiri bubi kandi bwiza bwifu ya WC bikoreshwa mugukata, aho ingano yubunini bwa poro ya WC ifu ya (20-30) μ m, naho ingano yubunini bwifu ya WC ni (1.2-1.8) μm.
Urebye kubisabwa, karubide ya tungsten na cobalt isima irashobora gukoreshwa mugukata ibyuma, ibyuma bidafite fer hamwe nibikoresho bitari ibyuma, hiyongereyeho no gukora ibikoresho byuruhande, gushushanya ibishushanyo, imbeho ikonje, nozzles, umuzingo, inyundo zo hejuru nibindi bikoresho birwanya kwambara nibikoresho byo gucukura.
