Ibyiza, ibibi, nibitandukaniro hagati yicyuma cyihuta na karbide ya sima
1. Icyuma cyihuta:
Icyuma cyihuta cyane ni karubone nyinshi kandi nicyuma kinini. Ukurikije imiterere yimiti, irashobora kugabanywamo urukurikirane rwa tungsten hamwe nicyuma cya molybdenum, kandi ukurikije imikorere yo guca, irashobora kugabanywamo ibyuma bisanzwe byihuta kandi byihuta cyane. Ibyuma byihuta bigomba gushimangirwa no kuvura ubushyuhe. Mugihe kizimye, icyuma, chromium, igice cya tungsten, na karubone mubyuma byihuta bikora karbide zikomeye, zishobora kunoza imyambarire yicyuma (gukomera birashobora kugera kuri HRC64-68).
Ikindi gice cya tungsten gishonga muri matrix kandi cyongera ubukana bwumutuku wibyuma. Ubukomezi butukura bwibyuma byihuta birashobora kugera kuri dogere 650. Icyuma cyihuta cyane gifite imbaraga nubukomere. Nyuma yo gukarisha, gukata birakaze kandi ubuziranenge burahagaze. Mubisanzwe bikoreshwa mugukora ibikoresho bito, bigoye.
2. Carbide ya sima:
Carbide ya sima ni micron-order retractory high-hard-metal powder ya karbide, ikorwa no kurasa ku bushyuhe bwinshi hamwe n’umuvuduko mwinshi hamwe na cobalt, molybdenum, nikel, nibindi nkibihuza. Ibiri muri karbide yubushyuhe bwo hejuru muri sima ya sima irenze iyibyuma byihuta, hamwe no gukomera (HRC75-94) hamwe no kwihanganira kwambara neza.
Gukomera gukomeye gutukura birashobora kugera kuri dogere 800-1000. Umuvuduko wo kugabanya karbide ya sima wikubye inshuro 4-7 ugereranije nicyuma cyihuta. Gukata neza.
Carbide ya sima ifite ubukana bwinshi, imbaraga, kurwanya-kwambara, no kwangirika kwangirika, kandi bizwi nka "amenyo yinganda". Ikoreshwa mugukora ibikoresho byo gutema, ibyuma, ibikoresho bya cobalt, nibice bidashobora kwambara, kandi bikoreshwa cyane mubisirikare, mu kirere no mu ndege, gutunganya imashini, metallurgjiya, gucukura peteroli, ibikoresho byo gucukura amabuye y'agaciro, itumanaho rya elegitoroniki, ubwubatsi, n'indi mirima, hamwe niterambere ryinganda zimanuka, isoko ryisoko rya karbide ya sima ikomeje kwiyongera. Kandi mu bihe biri imbere, gukora intwaro n’ibikoresho byo mu rwego rwo hejuru, guteza imbere ubumenyi n’ikoranabuhanga bigezweho, hamwe n’iterambere ryihuse ry’ingufu za kirimbuzi bizongera cyane icyifuzo cy’ibikoresho byo mu rwego rwo hejuru byujuje ubuziranenge, kandi bihamye bya sima ya sima. .
