Hua'ōlelo o ka Alloy Paʻa (2)

Decarbonization

Ma hope o ka sintering i ka cemented carbide, ʻaʻole lawa ka ʻike kalapona.

Ke hoʻopau ʻia ka huahana, hoʻololi ka ʻiʻo mai WC-Co a i W2CCo2 a i ʻole W3CCo3. ʻO ka maʻiʻo kalapona maikaʻi loa o ka tungsten carbide i ka cemented carbide (WC) he 6.13% ma ke kaumaha. Ke haʻahaʻa loa ka maʻiʻo kalapona, e ʻike ʻia kahi ʻano kalapona-deficient i loko o ka huahana. Hoʻemi nui ka Decarburization i ka ikaika o ka tungsten carbide sima a ʻoi aku ka palupalu.

Carburization

E pili ana ia i ka nui o ke kalapona ma hope o ka sintering i ka carbide cemented. ʻO ka maʻiʻo kalapona maikaʻi loa o ka tungsten carbide i ka cemented carbide (WC) he 6.13% ma ke kaumaha. Ke kiʻekiʻe loa ka ʻike kalapona, e ʻike ʻia kahi ʻano carburized i ʻōlelo ʻia i loko o ka huahana. E nui ana ke kalapona manuahi i loko o ka huahana. Hoʻemi nui ke kalapona manuahi i ka ikaika a me ka pale ʻana o ka tungsten carbide. Hōʻike nā pores C-type i ka ʻike ʻana i ke ʻano o ka carburization.

ʻO ka hoʻomakeʻe

ʻO ka ikaika koʻikoʻi ke koena o ka mana magnetic i ana ʻia ma ka hoʻopaneʻe ʻana i ka mea magnetic i loko o ka carbide cemented i kahi kūlana saturated a laila demagnetizing ia. Aia kahi pilina pololei ma waena o ka nui o ka nui o ka nui o ka māhele carbide cemented a me ka coercivity. ʻO ka ʻoi aku ka maikaʻi o ka nui o ka ʻāpana magnetized, ʻoi aku ka kiʻekiʻe o ka waiwai coercivity.

Saturation magnetic

ʻO ka Cobalt (Co) he magnetic, ʻoiai ʻo ka tungsten carbide (WC), titanium carbide (TiC), a me ka tantalum carbide (TaC) ʻaʻole ia he magnetic. No laila, ma ke ana mua ʻana i ka waiwai hoʻohui magnetic o ka cobalt i loko o kahi mea a laila hoʻohālikelike ʻia me ka waiwai kūpono o kahi hāpana cobalt maʻemaʻe, no ka mea, ua hoʻopili ʻia ka saturation magnetic e nā mea hoʻohuihui, hiki ke loaʻa ke kiʻekiʻe alloying o ka māhele paʻa kobalt. . Hiki ke ana ʻia nā hoʻololi ʻana o ka māhele binder. No ka mea he koʻikoʻi ke kalapona i ka mana haku mele, hiki ke hoʻohana ʻia kēia ʻano no ka hoʻoholo ʻana i nā ʻokoʻa mai ka maʻi kalapona kūpono. Hōʻike ʻia nā waiwai saturation magnetic haʻahaʻa haʻahaʻa a hiki i ka decarburization. Hōʻike nā waiwai saturation magnetic kiʻekiʻe i ka loaʻa ʻana o ke kalapona manuahi a me ka carburization.

Pool Cobalt

Ma hope o ka hoʻopaʻa ʻana i ka mea hoʻopaʻa metala cobalt (Co) a me ka tungsten carbide, hiki ke hoʻokumu ʻia ka cobalt keu, kahi mea i kapa ʻia ʻo "kobalt pooling". ʻO ka mea nui kēia ma muli o ke kaʻina HIP (Pressure Sintering), haʻahaʻa loa ka mahana o ka sintering a ʻaʻole lawa nā mea waiwai, a i ʻole ua hoʻopiha ʻia nā pores me ka cobalt. E hoʻoholo i ka nui o ka loko cobalt ma ka hoʻohālikelike ʻana i nā kiʻi metallographic. ʻO ka loaʻa ʻana o kahi loko cobalt i ka carbide cemented e pili ana i ka pale ʻana a me ka ikaika o ka mea.

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