ʻElua mau ʻano o ka Sintering

ʻO nā huahana Tungsten carbide i hui pū ʻia me ka tungsten carbide a me nā mea hui hao ʻē aʻe e like me ka cobalt ma ke ʻano he binder. Hiki ke hoʻohana nui ʻia nā huahana tungsten carbide i ka ʻoki ʻana i nā metala, nā ʻāpana ʻaila hinu, a me ka make metala.

Pono e mālama pono ʻia ka sintering tungsten carbide e kiʻi i ka microstructure kūpono a me ka hoʻohui ʻana. I nā noi he nui, hana ʻia ka tungsten carbide e ka pauka metallurgy, e komo pū ana me ka sintering. ʻO nā huahana tungsten carbide e kū pinepine i ka lole a me ka tensile i nā wahi paʻakikī. I ka hapa nui o nā noi metala, ua ʻoki ʻia nā mea ʻoki tungsten carbide me ka ʻaʻahu ma mua o 0.2-0.4 mm. No laila, koʻikoʻi nā waiwai o ka tungsten carbide.

ʻElua mau ala nui no ka sinter tungsten carbide huahana. ʻO kekahi ka hoʻoheheʻe hydrogen, a ʻo ka mea ʻē aʻe ʻo ka sintering vacuum. Ke hoʻomalu nei ʻo Hydrogen sintering i ka haku ʻana o nā ʻāpana e nā kinetics reaction reaction ma ka hydrogen a me ke kaomi; ʻO ka sintering vacuum ke hoʻomalu nei i ka composite o ka tungsten carbide ma o ka hoʻolohi ʻana i nā kinetics hopena ma lalo o kahi ʻōpala a haʻahaʻa haʻahaʻa.

ʻOi aku ka nui o ka hoʻohana ʻana i nā ʻoihana ʻenehana. I kekahi manawa, hiki i nā limahana ke hoʻohana i ka paʻi isostatic wela, he mea nui hoʻi ia no ka hana ʻana i nā huahana tungsten carbide.

I ka wā hoʻoheheʻe hydrogen, he lewa hoʻohaʻahaʻa ka hydrogen. Hiki i ka hydrogen ke hana me ka paia kapuahi sintering a i ʻole graphite a hoʻololi i nā mea ʻē aʻe.

Ke hoʻohālikelike ʻia me ka hydrogen sintering, ʻo ka vacuum sintering ka mea e pono ai.

ʻO ka mea mua, hiki i ka vacuum sintering ke hoʻomalu maikaʻi i ka haku mele ʻana o ka huahana. Ma lalo o ke kaomi o 1.3 ~ 133pa, he haʻahaʻa loa ke kumukūʻai o ke kalapona a me ka oxygen ma waena o ka lewa a me ka alloy. ʻO ka mea nui e pili ana i ka hoʻohui ʻana ʻo ia ka ʻike oxygen i nā ʻāpana carbide, no laila ʻoi aku ka maikaʻi o ka sintering vacuum i ka hana ʻoihana o ka tungsten carbide sintered.

ʻO ka lua, i ka wā o ka vacuum sintering, ʻoi aku ka maʻalahi o ka mālama ʻana i ka ʻōnaehana sintering, ʻoi aku ka nui o ka hoʻomehana ʻana, e hoʻokō i nā pono o ka hana. ʻO ka sintering vacuum he hana pūʻulu, ʻoi aku ka maʻalahi ma mua o ka sintering hydrogen.

I ka sintering tungsten carbide huahana, tungsten carbide pono e ʻike i nā pae aʻe:

1. Ka wehe ʻana i ka mea hoʻoheheʻe ʻia a me ka pae mua o ke ahi;

Ma kēia kaʻina hana, pono e hoʻonui mālie ʻia ka mahana, a hiki i kēia pae ma lalo o 1800 ℃.

2. Paʻa-ʻāpana sintering pae

Ke piʻi mālie nei ka mahana, hoʻomau ka sintering. Aia kēia pae ma waena o 1800 ℃ a me ka mahana eutectic.

3. ʻO ka pae wai sintering pae

I kēia pae, hoʻomau ka piʻi ʻana o ka mahana a hiki i ka wela kiʻekiʻe loa i ka hana sintering, ka mahana o ka sintering.

4. Ke kahua hooluolu

ʻO ka carbide i hoʻopaʻa ʻia, ma hope o ka sintering, hiki ke hoʻoneʻe ʻia mai ka umu hoʻoheheʻe ʻia a hoʻomaha ʻia i ka lumi wela.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
