1. ʻO ka mea nui o ka Carbide Cemented
Hana ʻia ka carbide i hoʻopaʻa ʻia me ka paʻakikī kiʻekiʻe, refractory metala carbide (WC, TiC) micron pauka e like me ka mea nui, me ka cobalt (Co), nickel (Ni), a me ka molybdenum (Mo) e like me ka mea hoʻopili. Hiki ke hoʻohana ʻia i loko o kahi umu ahi a i ʻole hydrogen Powder metallurgy huahana i hoʻopaʻa ʻia i loko o ka umu hoʻēmi.
O kahi laʻana:

2.The Compose o ka substrates o cemented carbide
Hoʻokumu ʻia nā substrates o ka carbide cemented i ʻelua mau ʻāpana: ʻo kahi ʻāpana ka pae paʻakikī, a ʻo kekahi ʻāpana ʻo ka metala paʻa.
ʻO ka māhele paʻakikī ka carbide o nā metala hoʻololi i ka papaʻaina, e like me ka tungsten carbide, titanium carbide, a me ka tantalum carbide. He kiʻekiʻe loa ko lākou paʻakikī, a ʻoi aku ko lākou mau wahi heheʻe ma luna o 2000 ° C, a ʻoi aku kekahi ma mua o 4000 ° C. Eia kekahi, ʻo nā nitrides metala hoʻololi, nā borides, a me nā silicides he mau ʻano like a hiki ke hana ma ke ʻano paʻakikī i ka carbide cemented. ʻO ka loaʻa ʻana o ka pae paʻakikī e hoʻoholo i ka paʻakikī kiʻekiʻe o ka alloy a me ke kūpaʻa ʻaʻahu.
ʻO ka metala paʻa ka mea maʻamau i nā metala hui hao, a hoʻohana mau ʻia ka cobalt a me ka nickel.

3. Pehea e hana ai kēlā me kēia māhele i ka hana
I ka hana ʻana i ka carbide cemented, ʻo ka nui o ka nui o ka pauka maka i koho ʻia e ka hale hana carbide cemented ma waena o 1 a me 2 microns, a kiʻekiʻe loa ka maʻemaʻe. Hoʻohui ʻia nā mea maka e like me ka ratio haku mele i ʻōlelo ʻia, a hoʻohui ʻia ka waiʻona a i ʻole nā ​​​​mea ʻē aʻe i ka wili pulu i loko o ka wili pōleʻa pulu e hui pū ʻia a paʻi. Ma hope o ka maloʻo ʻana a me ke kānana ʻana, hoʻohui ʻia kahi mea hana e like me ka wax a i ʻole ke kāpili. Loaʻa ka hui ʻana ma ke kānana ʻana. A laila, i ka wa a ka hui 'ana i granulated a kaomi, a me ka wela a kokoke i ka hehee ai o ka binder metala (1300-1500 ° C), ka paa paakiki a me ka binder metala e hana i ka eutectic alloy. Ma hope o ka hoʻoluʻu ʻana, māhele ʻia ka māhele paʻakikī i loko o ka pā i haku ʻia me ka metala paʻa, a pili pono kekahi i kekahi e hana i kahi holoʻokoʻa paʻa. ʻO ka paʻakikī o ka carbide i hoʻopaʻa ʻia e pili ana i ka maʻiʻo paʻakikī a me ka nui o ka palaoa, ʻo ia hoʻi, ʻoi aku ka kiʻekiʻe o ka maʻiʻo paʻakikī a ʻoi aku ka maikaʻi o ka ʻai, ʻoi aku ka paʻakikī. Hoʻoholo ʻia ka paʻakikī o ka carbide cemented e ka metala paʻa. ʻOi aku ka kiʻekiʻe o ka ʻike o ka metala paʻa, ʻoi aku ka nui o ka ikaika wili.
