ʻO ka pahuhopu tungsten i pīpī ʻia a sintered ʻia he mau ʻano o 99% density a ʻoi aku paha, ʻo ke anawaena ʻano aniani maʻamau he 100um a emi mai paha, ʻo ka nui o ka oxygen he 20ppm a emi mai paha, a ʻo ka ikaika deflection ma kahi o 500Mpa; hoʻomaikaʻi ia i ka hana ʻana o ka pauka metala i hana ʻole ʻia No ka hoʻomaikaʻi ʻana i ka hiki ke sintering, hiki ke hoʻopaʻa ʻia ke kumukūʻai o ka pahuhopu tungsten ma ke kumu kūʻai haʻahaʻa. Loaʻa i ka pahuhopu tungsten sintered kahi density kiʻekiʻe, he kiʻi aniani kiʻekiʻe i hiki ʻole ke hoʻokō ʻia e ke ʻano kaomi a me ka sintering kuʻuna, a hoʻomaikaʻi nui i ke kihi deflection, i hoʻemi nui ʻia ai ka mea particulate.
Pōmaikaʻi
(1) ʻIli laumania me ka ʻole o ka pore, ka ʻōpala a me nā hemahema ʻē aʻe
(2) Wili a ʻoki paha i ka lihi, ʻaʻohe māka ʻoki
(3) Ka helu lanakila ʻole o ka maʻemaʻe o nā mea
(4) Ke kiʻekiʻe o ka ductility
(5) Hoʻohuihui liʻiliʻi like
(6) Ka māka laser no kāu mea kūikawā me ka inoa, ka lama, ka nui o ka maʻemaʻe a pēlā aku
(7) ʻO kēlā me kēia pcs o nā pahuhopu sputtering mai ka mea a me ka helu o nā mea pauka, nā limahana hoʻohuihui, nā outgas a me ka manawa HIP, ka mea hana mīkini a me nā kikoʻī hoʻopili ʻana ua hana ʻia mākou iho.
Hiki i kēlā mau ʻanuʻu āpau ke hoʻohiki iā ʻoe i ka wā e hana ʻia ai kahi pahuhopu sputtering hou a i ʻole ke ʻano hana, hiki ke kope ʻia a mālama ʻia e kākoʻo i nā huahana maikaʻi paʻa.
Nā pono ʻē aʻe
Nā mea hana kiʻekiʻe
(1) 100% ka nui o ka paʻa = 19.35 g/cm³
(2) Paʻa o ke ana
(3) Nā waiwai mechanical i hoʻonui ʻia
(4) Ka hoʻolaha like ʻana o ka nui o ka palaoa
(5) Nā ʻano hua liʻiliʻi
ʻApalakia
Hoʻohana nui ʻia ka mea i hoʻohana ʻia no ka hoʻoheheʻe ʻana i ka honua laha ʻole, nā kukui uila, nā lako kemika, nā lako lapaʻau, nā mīkini metallurgical, nā lako hoʻoheheʻe, ka ʻaila a me nā ʻoihana ʻē aʻe.
