I nā makahiki i hala iho nei, ua hoʻohana nui ʻia nā mea hana ʻokiʻoki PCD i nā ʻoihana hana o ka alumini, nā alumini alumini, ke keleawe, a me kekahi mau mea non-metallic.
He aha nā pōmaikaʻi o nā mea ʻoki ʻoki PCD i ka hoʻoili alumini a pehea e koho ai i nā mea ʻoki PCD kūpono?
He aha nāNā mea hana ʻoki PCD？
ʻO nā mea hana ʻoki PCD e pili ana i nā mea hana daimana polycrystalline.Hoʻopili ʻia ka pepa PCD composite i hoʻohana ʻia mai ka pauka daimana kūlohelohe a i hana ʻia paha a me nā mea hoʻopaʻa (loaʻa nā metala e like me ka cobalt a me ka nickel) i kekahi ʻāpana i ka wela kiʻekiʻe (1000-2000 ℃) a me ke kaomi kiʻekiʻe (50000 a 100000 atmospheres).ʻAʻole wale ia i ka paʻakikī kiʻekiʻe a me ka pale ʻana o ka PCD, akā loaʻa pū kekahi i ka ikaika a me ka paʻakikī o ka carbide.
Ma hope o ka hana ʻia ʻana i mea hana ʻokiʻoki, loaʻa iā ia nā ʻano o ka paʻakikī kiʻekiʻe, kiʻekiʻe thermal conductivity, haʻahaʻa thermal expansion coefficient, kiʻekiʻe elastic modulus, a haʻahaʻa friction coefficient.
ʻO nā mea hana ʻoki ʻo OPT kahi mea hoʻokomo PCD kiʻekiʻe kiʻekiʻe, Kākoʻo mākou iā ʻoe i ke kūʻai ʻana i kāu mau koi makahiki ma nā kumukūʻai hoʻokūkū, e hāʻawi ana i ke ʻano kiʻekiʻe a me ka laulā o nā lawelawe.
Nā pōmaikaʻi o ka PCD hoʻokomo i ka hana alumini
(1) Hiki i ka paʻakikī o nā mea hana PCD ke hiki i 8000HV (80-120 mau manawa o ka carbide)
a maikaʻi loa ko lākou pale ʻana.
(2) ʻO ka conductivity thermal o nā mea hana PCD he 700W/MK (1.5-9 mau manawa o ka carbide), kahi e hoʻonui nui ai i ke ola mea hana ma muli o kāna hana hoʻololi wela maikaʻi loa.
(3) He 0.1 a i ka 0.3 wale nō ka nui o ka friction coefficient o nā mea hana PCD, ʻoi aku ka haʻahaʻa ma mua o ka carbide, hiki ke hōʻemi nui i ka ʻoki ʻana a hoʻonui i ke ola mea hana.
(4) Loaʻa i nā mea hana PCD ka helu liʻiliʻi o ka hoʻonui ʻana i ka wela, ka liʻiliʻi liʻiliʻi thermal deformation, kiʻekiʻe machining pololei a me ka mea hana kiʻekiʻe o ka ʻili.
(5) He haʻahaʻa haʻahaʻa ka ili o nā mea ʻoki ʻoki PCD me nā mea non-ferrous a me nā mea ʻole, no laila ʻaʻole maʻalahi ka hana ʻana i ka chip buildup.
(6) Loaʻa i nā mea hana PCD ka modulus elastic kiʻekiʻe a ʻaʻole hiki ke haki.ʻO ka radius blunt o ka ʻoki ʻoki hiki ke hoʻoheheʻe liʻiliʻi loa, hiki ke mālama i ka ʻoi o ka ʻokiʻoki no ka manawa lōʻihi.
Ma muli o nā pono i luna aʻe, hiki i nā mea hana PCD ke hana i nā mea alumini alumini i ka wikiwiki loa, me ke ola mea hana o nā tausani a i ʻumi kaukani mau ʻāpana.Maikaʻi no ka hana nui o ka wikiwiki a me ka ʻoki kiʻekiʻe (3C digital, automotive industry, aerospace field), e like me ka hoʻoponopono ʻana i nā pūpū huahana kikohoʻe, nā piston automotive, nā huila kaʻa, nā apo wili, etc.
Pehea e koho ai Nā mea hana ʻoki PCD?
ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o ka nui o ka PCD, ʻoi aku ka ikaika o ka pale ʻana o ka mea hana.
ʻO ka maʻamau, hoʻohana ʻia ka PCD ʻāpana maikaʻi no ka mīkini kikoʻī a i ʻole ultra precision machining, ʻoiai hoʻohana ʻia nā mea hana PCD ʻāpana koʻikoʻi no ka mīkini palaki.
Manaʻo pinepine nā mea hana i ka hoʻohana ʻana i nā māka PCD maikaʻi no ka hoʻomaʻamaʻa ʻana i nā mea hoʻoheheʻe silika aluminika haʻahaʻa, a me ka hoʻohana ʻana i nā māka PCD coarse-grained no ka hoʻoponopono ʻana i nā mea hao alumini silika kiʻekiʻe, no ke kumu like.
ʻO ka maikaʻi o ka ʻili i hana ʻia e nā mea hana PCD ʻaʻole i hilinaʻi wale i ka nui o ka mea hana, akā i ka maikaʻi o ka ʻaoʻao o ka mea hana, no laila e ʻoi aku ka maikaʻi o nā mea hana PCD.
ʻElua mau kaʻina hana maʻamau no nā ʻaoʻao mea hana PCD, ʻo kekahi ma o ka ʻoki uwea lohi.He haʻahaʻa nā kumukūʻai o kēia ʻano hana, akā ʻo ka maikaʻi o nā kihi he awelika.Loaʻa ke ʻano ʻē aʻe ma o ka hoʻoili ʻana i ka laser, ʻoi aku ka nui o ke kumukūʻai, akā ʻoi aku ka kiʻekiʻe o ka maikaʻi o ka ʻoki ʻoki (aia pū kekahi ʻano hana o ka mīkini ʻokiʻoki mua a laila wili i ka mīkini pololei, ʻoi aku ka maikaʻi o ka ʻoki ʻana. lihi).Pono nō e uku hou aku i ke koho ʻana.
ʻO ka ʻōlelo koʻikoʻi, ʻo ia wale nō.ʻO nā kikoʻī kikoʻī ʻē aʻe, me ke kumukūʻai a me ka ʻoki ʻana, pono e nānā i nā ʻāpana huahana kikoʻī i hāʻawi ʻia e nā mea hana like ʻole.Eia kekahi, ma kahi o ke koho kūpono o ka geometry mea hana a me ka ʻoki ʻana i nā ʻāpana, koi ʻia ka hana alumini i kekahi manawa i nā mea hoʻolako mea hana e hāʻawi i nā hoʻonā i nā pilikia i loaʻa i ka wā hoʻohana mea hana.
