ʻO ke kaʻina hana o ka mea hana PCD e hoʻoholo pololei i ka hana ʻoki a me ke ola lawelawe o ka hāmeʻa, ʻo ia ke kī o kāna noi a me ka hoʻomohala ʻana. Hōʻike ʻia ke kaʻina hana o ka mea hana PCD ma ke Kiʻi 5.
(1) Ka hana ʻana i nā papa huila PCD (PDC)
① Kaʻina hana o ka PDC
Hoʻokumu ʻia ka PDC me ka pauka daimana maoli a i ʻole synthetic a me ka mea hoʻopaʻa paʻa i ka wela kiʻekiʻe (1000-2000 ℃) a me ke kaomi kiʻekiʻe (5-10 atm).

Hana ʻia ʻo PDC i nā diski me ke anawaena paʻa a me ka mānoanoa, a me ka wili ʻana a me ka poli a me nā lāʻau lapaʻau kino a me nā kemika. I ka mea nui, pono ke ʻano maikaʻi o ka PDC e mālama i nā hiʻohiʻona kino maikaʻi loa o ka daimana aniani hoʻokahi e like me ka hiki, no laila, ʻoi aku ka liʻiliʻi o nā mea hoʻohui i loko o ke kino sintering, i ka manawa like, ʻo ka hui pū ʻana o nā mea paʻa DD e like me ka hiki.
② Hoʻokaʻawale a koho ʻana i nā mea paʻa
ʻO ka mea paʻa ka mea koʻikoʻi e pili ana i ka paʻa wela o ka mea hana PCD, e pili pono ana i kona paʻakikī, ke kūpaʻa a me ke kūpaʻa wela. ʻO nā ʻano hana hoʻopaʻa PCD maʻamau: hao, cobalt, nickel a me nā metala hoʻololi ʻē aʻe. Ua hoʻohana ʻia ʻo Co a me W i hui pū ʻia e like me ka mea hoʻopaʻa paʻa, a ʻoi aku ka maikaʻi o ka hana piha o ka sintering PCD i ka wā o ke kaomi synthesis he 5.5 GPa, ʻo ka mahana sintering he 1450 ℃ a me ka insulation no 4min. SiC, TiC, WC, TiB2, a me nā mea seramika ʻē aʻe. SiC Ua ʻoi aku ka maikaʻi o ke kūpaʻa wela o SiC ma mua o ko Co, akā ʻoi aku ka haʻahaʻa o ka paʻakikī a me ka paʻakikī. Hiki ke hoʻonui i ka paʻakikī a me ka paʻakikī o ka PCD ma ka hoʻemi kūpono o ka nui o nā mea maka. ʻAʻohe mea hoʻopili, me ka graphite a i ʻole nā kumu kalapona ʻē aʻe i ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe i puhi ʻia i loko o kahi nanoscale polymer diamond (NPD). ʻO ka hoʻohana ʻana i ka graphite e like me ka precursor no ka hoʻomākaukau ʻana i ka NPD ʻo ia nā kūlana koʻikoʻi loa, akā ʻo ka NPD synthetic ka mea paʻakikī kiʻekiʻe loa a me nā waiwai mechanical maikaʻi loa.
ʻO ke koho ʻana a me ka hoʻomalu ʻana i nā hua ③
ʻO ka pauka daimana maka he kumu nui e pili ana i ka hana o PCD. ʻO ka hoʻomaʻamaʻa ʻana i ka micropowder daimana, me ka hoʻohui ʻana i kahi mea liʻiliʻi e pale ana i ka ulu ʻana o nā ʻāpana daimana maʻamau a me ke koho kūpono o nā mea hoʻohui sintering hiki ke kāohi i ka ulu ʻana o nā ʻāpana daimana maʻamau.
Hiki i ka NPD maʻemaʻe kiʻekiʻe me kahi ʻano like ʻole ke hoʻopau pono i ka anisotropy a hoʻomaikaʻi hou i nā waiwai mechanical. ʻO ka nanographite precursor pauka i hoʻomākaukau ʻia e ke ʻano wili pōleʻa kiʻekiʻe i hoʻohana ʻia e hoʻoponopono i ka ʻike o ka oxygen i ke kiʻekiʻe kiʻekiʻe pre-sintering, hoʻololi i ka graphite i daimana ma lalo o 18 GPa a me 2100-2300 ℃, e hana ana i ka lamella a me ka granular NPD, a ua hoʻonui ka paʻakikī me ka emi ʻana o ka mānoanoa lamella.
④ Lapaʻau kemika lohi
Ma ka mahana like (200 ° ℃) a me ka manawa (20h), ʻoi aku ka maikaʻi o ka hopena hoʻoneʻe cobalt o Lewis acid-FeCl3 ma mua o ka wai, a ʻo ka lākiō maikaʻi loa o HCl he 10-15g / 100ml. Hoʻomaikaʻi ka paʻa wela o ka PCD i ka piʻi ʻana o ka hohonu hoʻoneʻe cobalt. No ka ulu ʻana o ka PCD, hiki i ka mālama ʻana i ka waikawa ikaika ke hoʻopau loa iā Co, akā he mana nui i ka hana polymer; e hoʻohui iā TiC a me WC e hoʻololi i ke ʻano polycrystal synthetic a hui pū me ka lāʻau waikawa ikaika e hoʻomaikaʻi i ka paʻa o PCD. I kēia manawa, hoʻomaikaʻi ka hana hoʻomākaukau o nā mea PCD, maikaʻi ka paʻakikī o ka huahana, ua hoʻomaikaʻi maikaʻi ʻia ka anisotropy, ua ʻike i ka hana pāʻoihana, e ulu wikiwiki ana nā ʻoihana pili.
