Ibisobanuro
FIELD: metallurgie.
SUBSTANCE: guhimba bifitanye isano na powder metallurgie yumurima.By'umwihariko bifitanye isano no kwakira ibinini byacumuye bishingiye kuri tungsten karbide.Irashobora gukoreshwa mugukora imashini, imyitozo no gusya.Amavuta akomeye arimo 80.0-82.0 wt% tungsten karbide na 18.0-20.0 wt% yo guhambira.Guhambira birimo, wt%: molybdenum 48.0-50.0;niobium 1.0-2.0;rhenium 10.0-12.0;cobalt 36.0-41.0.
INGARUKA: kwakira imbaraga zikomeye.
Ibisobanuro
Ivumburwa rijyanye n'umurima w'ifu ya metallurgie no gukora ibicuruzwa bivanze cyane bishingiye kuri karubide ya tungsten, ishobora gukoreshwa mu gukora imashini, imyitozo, urusyo n'ibindi bikoresho.
Azwiho gucumura karbide ishingiye kuri karubide ya tungsten, irimo 3.0 kugeza 20.0 wt.% Amavuta ya binder arimo, wt.%: Cobalt 20.0-75.0;molybdenum - kugeza 5.0;niobium - kugeza kuri 3.0 [1].
Intego yo guhanga ni ukongera imbaraga za alloy.
Igisubizo cya tekiniki kigerwaho muburyo bwo gucumura gukomeye gushingiye kuri karubide ya tungsten irimo 80.0-82.0 wt.% Carbide ya Tungsten na 18.0-20.0 wt.% Binder, binder irimo, wt.%: Molybdenum 48 0-50.0;niobium 1.0-2.0, rhenium 10.0-12.0;cobalt 36.0-41.0.
Imbonerahamwe.1 yerekana ibigize amavuta, kimwe nimbaraga zanyuma mukunama.Imbonerahamwe.2 yerekana ibice bigize ligament.
Imbonerahamwe 1 Ibigize Ibigize, wt.
Imbonerahamwe 2. Ibigize Ibigize, wt.%: Umwe 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 yibigize ibivangwa bivangwa nuburinganire bwerekanwe, imvange ikanda kotswa igitutu cya 4.5-4.8 t / cm 2 hanyuma ikayungurura mu itanura ryamashanyarazi ku bushyuhe bwa 1300-1330 ° C muri vacuum mumasaha 7-9.Mugihe cyo gucumura, binder ishonga igice cya karubide ya tungsten igashonga.Igisubizo ni ibintu byuzuye bifite imiterere igizwe na tungsten karbide ibice bihujwe na binder.
