Incamake
UMURIMO: ubucukuzi bw'ibyuma.
IBIKORESHO: Ubuvumbuzi bujyanye n'ubutaka bw'icyuma gikozwe mu ifu. Cyane cyane bujyanye no kwakira aloyi ikomeye ikozwe mu buryo bwa sintered hashingiwe kuri tungsten carbide. Ishobora gukoreshwa mu gukora imashini zikata, imashini zikoresha imashini zisya. Aloyi ikomeye irimo 80.0-82.0 wt % tungsten carbide na 18.0-20.0 wt % yo gufatana. Gufatana birimo, %: molybdenum 48.0-50.0; niobium 1.0-2.0; rhenium 10.0-12.0; cobalt 36.0-41.0.
INGARUKA: kwakira ifu y'icyuma gikomeye cyane.
Ibisobanuro
Ubu buvumbuzi bujyanye n'urwego rw'ubuhanga mu by'ibyuma biva mu ifu no gukora imashini zikomeye zikozwe muri tungsten carbide, zishobora gukoreshwa mu gukora imashini zikata, imashini zitobora, inganda n'ibindi bikoresho.
Karubide izwi ikoze mu buryo bwa sintered ishingiye kuri karubide ya tungsten, irimo ubunini bwa 3.0 kugeza kuri 20.0%. Ingano irimo ubunini bwa %: Cobalt 20.0-75.0; molybdenum - kugeza kuri 5.0; niobium - kugeza kuri 3.0 [1].
Intego y'ubu buvumbuzi ni ukongera imbaraga z'icyuma gikoze mu byuma.
Umusaruro wa tekiniki uboneka kuko mu cyuma gikomeye gikozwe muri tungsten carbide kirimo 80.0-82.0 wt. % Tungsten carbide na 18.0-20.0 wt. % Binder, icyo cyuma gikubiyemo, wt.%: Molybdenum 48 0-50.0; niobium 1.0-2.0, rhenium 10.0-12.0; cobalt 36.0-41.0.
Muri iyi mbonerahamwe. 1 igaragaza imiterere y'icyuma gikoze mu ruganda, ndetse n'imbaraga zikomeye mu kugonda. Muri iyi mbonerahamwe. 2 igaragaza imiterere y'umugozi.
Imbonerahamwe ya 1 Ibice bigize, uburemere%: kimwe 2 3 Wolfram carbide 80.0 81.0 82.0 Itsinda 20.0 19.0 18.0 Ingufu zo gupfunyika, MPa ~ 1950 ~ 1950 ~ 1950
Imbonerahamwe ya 2. Ibice bigize, uburemere%: kimwe 2 3 Molybdenum 48.0 49.0 50,0 Niobium 1,0 1,5 2.0 Rhenium 10.0 11.0 12.0 Cobalt 41.0 38.5 36.0
Ifu y'ibice by'aloyi ivangwa mu rugero rwagaragajwe, uruvange rushyirwa ku gitutu cya 4.5-4.8 t / cm 2 hanyuma rugacukurwa mu itanura ry'amashanyarazi ku bushyuhe bwa 1300-1330 ° C mu cyuma gishyuha amasaha 7-9. Mu gihe cyo gucukura, icyuma gishonga igice cya karubide ya tungsten kigashonga. Umusaruro uba ibikoresho byinshi bifite imiterere igizwe n'uduce twa karubide ya tungsten duhujwe n'icyuma gifunga.
