Ibikorwa biranga ibikoresho byo gukata karbide

Hard Gukomera cyane: ibikoresho bya sima ya sima bikozwe muri karbide ifite ubukana bwinshi hamwe no gushonga (byitwa icyiciro gikomeye) hamwe nicyuma gihuza (bita fonction bond) hakoreshejwe ifu ya metallurgie, ubukana bwayo bugera kuri 89 ~ 93HRA, hejuru cyane yicyuma cyihuta, kuri 5400C, ubukana burashobora kugera kuri 82 ~ 87HRA, kandi ibyuma byihuta byihuta mubushyuhe bwicyumba (83 ~ 86HRA) kimwe.Agaciro gakomeye ka karbide ya sima iratandukanye na kamere, ubwinshi, ingano yingirakamaro hamwe nibiri murwego rwo guhuza ibyuma, kandi muri rusange bigabanuka hamwe no kwiyongera kwibiri mubyiciro byicyuma.Ubukomezi bwa YT alloy burenze ubwa YG alloy mugihe ibikubiye murwego rwo guhuza ari bimwe, kandi ibivanze hamwe na TaC (NbC) bifite ubushyuhe bwo hejuru cyane.

Imbaraga zo kunama no gukomera: imbaraga zo kugonda za karbide zikoreshwa cyane muri sima iri hagati ya 900 ~ 1500MPa.Iyo ibintu byinshi biri murwego rwo guhuza ibyuma, niko imbaraga zunama.Iyo ibikubiye muri adhesive ari bimwe, imbaraga za YG (WC-Co) zivanze zirenze iz'umusemburo wa YT (WC-TiC-Co), kandi imbaraga zigabanuka hamwe no kwiyongera kwa TiC.Tungsten karbide ni ibintu byoroshye, kandi ingaruka zabyo mubushyuhe bwicyumba ni 1/30 kugeza 1/8 cyibyuma byihuta.

(3) Gukoresha ibikoresho bya karbide bisanzwe

Amavuta ya YG akoreshwa cyane mugutunganya ibyuma, ibyuma bidafite fer nibikoresho bitari ibyuma.Carbide nziza-nziza (nka YG3X, YG6X) mubwinshi bwa cobalt kurenza ubukana bwimbuto no kwihanganira kwambara ni byinshi, bikwiriye gutunganyirizwa ibyuma bidasanzwe bidasanzwe, ibyuma bitagira umuyonga wa austenitis, ibyuma birwanya ubushyuhe, amavuta ya titanium, umuringa ukomeye n'ibikoresho byo kwihanganira kwambara.

Ibyiza byingenzi bya YT urwego rwa sima ya karbide ni ubukana bwinshi, kurwanya ubushyuhe bwiza, ubukonje bukabije hamwe nimbaraga zo kwikuramo kurusha YG icyiciro, kurwanya okiside nziza.Kubwibyo, mugihe icyuma gisabwa kugira ubushyuhe bwinshi no kwihanganira kwambara, ikirango kirimo TiC kiri hejuru kigomba guhitamo.YT alloy ikwiranye no gutunganya ibikoresho bya pulasitike nkibyuma, ariko ntibikwiriye gutunganyirizwa titanium, silicon aluminium.

Amavuta ya YW afite imiterere ya YG na YT, kandi afite ibintu byiza byuzuye.Irashobora gukoreshwa mugutunganya ibyuma, ibyuma hamwe nibyuma bidafite fer.Amavuta nk'aya, niba yongerewe neza ibirimo cobalt, birashobora gukomera cyane kandi birashobora gukoreshwa mugukora imashini no gukata rimwe na rimwe ibikoresho bitandukanye bigoye.
