Loaʻa i nā ʻāpana Titanium nā waiwai mechanical maikaʻi loa akā ʻoi aku ka maikaʻi o ke kaʻina hana, kahi e alakaʻi ai i ka kūʻē ʻana i kā lākou noi noi e hoʻohiki nei akā paʻakikī ka hana. Ma kēia pepa, ma ka nānā ʻana i ka hana ʻoki metala o nā mea hao titanium, i hui pū ʻia me nā makahiki he nui o ka ʻike hana hana, ke koho ʻana i nā mea ʻoki ʻoki titanium alloy, ka hoʻoholo ʻana i ka wikiwiki o ka ʻoki ʻana, nā ʻano o nā ʻano ʻoki like ʻole, nā alana mīkini a me nā mālama mālama. kūkākūkā ʻia. Hōʻike ia i kaʻu mau manaʻo a me nā manaʻo e pili ana i ka hana ʻana i nā alloys titanium.
ʻO ka Titanium alloy he haʻahaʻa haʻahaʻa, ikaika kikoʻī kiʻekiʻe (ikaika/density), kūpaʻa ʻino maikaʻi, kūpaʻa wela kiʻekiʻe, paʻakikī maikaʻi, plasticity a me ka weldability. Ua hoʻohana nui ʻia nā alloys Titanium i nā kula he nui. Eia nō naʻe, ʻaʻole maikaʻi ka hana wela, ka paʻakikī kiʻekiʻe, a me ka modulus elastic haʻahaʻa e hoʻolilo i nā alloys titanium i mea metala paʻakikī e hana. Hōʻuluʻulu kēia ʻatikala i kekahi mau hana ʻenehana i ka hana ʻana i nā alloys titanium e pili ana i kona ʻano ʻenehana.
ʻO nā pōmaikaʻi nui o nā mea hao titanium
(1) Loaʻa ka ikaika kiʻekiʻe o ka alloy Titanium, haʻahaʻa haʻahaʻa (4.4kg / dm3) a me ke kaumaha māmā, e hāʻawi ana i kahi hopena no ka hōʻemi ʻana i ke kaumaha o kekahi mau ʻāpana kūkulu nui.
(2) Ka ikaika wela kiʻekiʻe. Hiki ke mālama i ka ikaika kiʻekiʻe ma lalo o ke kūlana o 400-500 ℃ a hiki ke hana paʻa, ʻoiai ka mahana hana o nā alumini alumini ma lalo o 200 ℃.
(3) Ke hoʻohālikelike ʻia me ke kila, ʻo ke kūpaʻa koʻikoʻi kiʻekiʻe o ka titanium alloy hiki ke mālama i ke kumukūʻai o ka hana i kēlā me kēia lā a me ka mālama ʻana i nā mokulele.
Ka nānā 'ana i nā 'ano machining o ka titanium alloy
(1) Haʻahaʻa thermal conductivity. ʻO ka conductivity wela o TC4 ma 200 °C he l=16.8W/m, a ʻo ka conductivity wela he 0.036 kal/cm, ʻo ia wale nō ka 1/4 o ke kila, 1/13 o ka alumini a me 1/25 o ke keleawe. I ke kaʻina hana ʻoki, ʻilihune ka hoʻoheheʻe ʻana o ka wela a me ka hopena hoʻoluʻu, e hōʻemi ana i ke ola mea hana.
(2) He haʻahaʻa ka modulus elastic, a ʻo ka ʻili mīkini o ka ʻāpana he rebound nui, e alakaʻi ana i ka hoʻonui ʻana i ka wahi pili ma waena o ka ʻili mīkini a me ka ʻaoʻao o ka ʻaoʻao o ka mea hana, ʻaʻole ia e pili wale i ka pololei o ka dimensional. ka ʻāpana, akā hoʻemi hoʻi i ka lōʻihi o ka mea hana.
(3) ʻAʻole maikaʻi ka hana palekana i ka wā ʻoki. ʻO ka Titanium he metala lapalapa, a ʻo ke kiʻekiʻe o ka wela a me nā ʻulaʻula i hana ʻia i ka wā ʻokiʻoki liʻiliʻi hiki ke hoʻopau i nā ʻāpana titanium e ʻā.
(4) Ke kumu oolea. ʻO nā'āpana Titanium me ka waiwai paʻakikī haʻahaʻa e paʻa i ka wā e hanaʻia ai, a e pili nā'āpana i kaʻokiʻoki o ka maka rake o ka mea hana e hana i kahi lihi i kūkuluʻia, e pili ana i ka hopena machining; ʻO nā alloys titanium me ka waiwai paʻakikī kiʻekiʻe e maʻalahi i ka ʻokiʻoki a me ka abrasion o ka mea hana i ka wā o ka mīkini. ʻO kēia mau hiʻohiʻona e alakaʻi i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka titanium alloy, ʻo ia wale nō ka 1/4 o ke kila, a ʻoi aku ka lōʻihi o ka manawa hana ma mua o ke kila o ka nui like.
(5) Pilikino ikaika. ʻAʻole hiki i ka Titanium ke hana kemika wale nō me nā mea nui o ka nitrogen, oxygen, carbon monoxide a me nā mea ʻē aʻe i ka lewa e hana i kahi papa paʻakikī o TiC a me TiN ma ka ʻili o ka alloy, akā e hana pū me ka mea hana ma lalo o ka wela kiʻekiʻe. nā kūlana i hanaʻia e kaʻokiʻokiʻana, e ho'ēmi ana i ka mea hanaʻoki. o ka lōʻihi.
