Uburyo bubiri bwo gucumura

Ibicuruzwa bya karubide ya Tungsten bigizwe na tungsten karbide nibindi bikoresho byitsinda ryicyuma nka cobalt nka binder. Ibicuruzwa bya karubide ya Tungsten birashobora gukoreshwa cyane mugukata ibyuma, gucukura amavuta, hamwe no gukora ibyuma bipfa.

Tungsten carbide sintering igomba kugenzurwa neza kugirango ubone microstructure nziza hamwe nibigize imiti. Mubikorwa byinshi, tungsten karbide ikorwa na powder metallurgie, ikubiyemo gucumura. Tungsten carbide ibicuruzwa akenshi birwanya kwambara no guhindagurika mubidukikije bikaze. Mubice byinshi byo gukata ibyuma, tungsten karbide ikata imyenda irenga mm 0.2-0.4 mm isuzumwa. Kubwibyo, imiterere ya karubide ya tungsten ni ngombwa.

Hariho uburyo bubiri bwingenzi bwo gucumura tungsten carbide ibicuruzwa. Imwe ni gucumura hydrogène, indi ni gucumura. Guhindura hydrogène ni ukugenzura ibice byicyiciro cya reaction reaction ya hydrogène nigitutu; gucumura vacuum ni ukugenzura ibice bya karubide ya tungsten mukugabanya umuvuduko wibikorwa bya vacuum cyangwa ikirere cyumuyaga muke.

Vacuum sintering ifite intera nini yinganda zikoreshwa. Rimwe na rimwe, abakozi barashobora gukoresha imashini isotatike ishyushye, nayo ni ngombwa mu gukora ibicuruzwa bya tungsten karbide.

Mugihe cyo gucumura hydrogène, hydrogen nikirere kigabanya. Hydrogen irashobora kwitwara hamwe nurukuta rw'itanura cyangwa grafite hanyuma igahindura ibindi bice.

Ugereranije no gucana hydrogène, gucumura vacuum bifite ibyiza bikurikira.

Mbere ya byose, gucumura vacuum birashobora kugenzura neza ibicuruzwa neza. Kumuvuduko wa 1.3 ~ 133pa, igipimo cyo kuvunja karubone na ogisijeni hagati yikirere na alloy ni gito cyane. Ikintu nyamukuru kigira ingaruka kubigize ni ogisijeni iri mu bice bya karubide, bityo gucumura vacuum bifite inyungu nini mu nganda zikora inganda za karubide ya tungsten.

Icya kabiri, mugihe cyo gucumura vacuum, biroroshye cyane kugenzura sisitemu yo gucumura, cyane cyane igipimo cyo gushyushya, kugirango ibikenerwa byumusaruro. Gucumura Vacuum nigikorwa cyicyiciro, cyoroshye kuruta hydrogène.

Iyo gucumura ibicuruzwa bya tungsten, karbide ya tungsten igomba guhura nibyiciro bikurikira:

1. Kuvanaho imashini ikora mbere yo gutwika;

Muri ubu buryo, ubushyuhe bugomba kwiyongera buhoro buhoro, kandi iki cyiciro kiba munsi ya 1800 ℃.

2. Icyiciro gikomeye cyo gucumura

Mugihe ubushyuhe bugenda bwiyongera buhoro buhoro, gucumura birakomeza. Iki cyiciro kibaho hagati ya 1800 ℃ nubushyuhe bwa eutectic.

3. Icyiciro cyamazi yo gucumura

Kuri iki cyiciro, ubushyuhe bukomeza kwiyongera kugeza bugeze ku bushyuhe bwo hejuru murwego rwo gucumura, ubushyuhe bwo gucumura.

4. Icyiciro gikonje

Carbide ya sima, nyuma yo gucumura, irashobora gukurwa mu itanura ryacumuye hanyuma igakonja kugeza ubushyuhe bwicyumba.

Niba ushimishijwe nibicuruzwa bya tungsten ukaba ushaka amakuru arambuye, urashobora kutwandikira ukoresheje terefone cyangwa amabaruwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
