Ma mua o ka kūkākūkā ʻana o kekahi mau mea kūʻai e pili ana i ka titanium alloy, a manaʻo lākou he pilikia loa ka hana ʻana o ka titanium alloy.I kēia manawa, e haʻi aku nā hoa hana mai RSM Technology Department iā ʻoe no ke aha mākou e manaʻo ai he mea paʻakikī ka titanium alloy?Ma muli o ka nele o ka ʻike hohonu i kāna ʻano hana a me nā hanana.
1. Nā hanana kino o ka hana titanium
ʻOi aku ka kiʻekiʻe o ka ʻokiʻoki o ka titanium alloy ma mua o ke kila me ka paʻakikī like, akā ʻoi aku ka paʻakikī o ke ʻano kino o ka hana ʻana o ka titanium alloy ma mua o ka hana kila, e hana ai i ka hana ʻana o ka titanium alloy i nā pilikia nui.
He haʻahaʻa loa ka conductivity thermal o ka hapa nui o nā alloys titanium, ʻo 1/7 wale nō o ke kila a me 1/16 o ka alumini.No laila, ʻaʻole e hoʻoneʻe koke ʻia ka wela i hana ʻia i ke kaʻina hana o ka titanium alloy i ka mea hana a i ʻole e lawe ʻia e nā ʻāpana, akā e hoʻopaʻa ʻia i ka ʻoki ʻana, a hiki ke kiʻekiʻe ke kiʻekiʻe e like me 1000 ℃ a i luna. no laila hiki i ka ʻoki ʻoki o ka mea hana ke komo wikiwiki, ʻāhaʻi a hoʻoulu i nā maʻi puʻupuʻu chip accretion.Hiki i ka ʻoki ʻoki wikiwiki ʻana ke hoʻonui i ka wela ma ka wahi ʻoki, e hoʻopōkole i ke ola o ka mea hana.
ʻO ka wela kiʻekiʻe i hana ʻia i ke kaʻina ʻokiʻoki e hoʻopau i ka pono o ka ʻili o nā ʻāpana alloy titanium, e alakaʻi ana i ka emi ʻana o ka pololei geometric o nā ʻāpana a me ka puka ʻana o ka hana paʻakikī e hōʻemi nui i ko lākou ikaika luhi.
Hiki i ka elasticity o ka titanium alloy ke kōkua i ka hana o nā ʻāpana, akā i ke kaʻina ʻokiʻoki, ʻo ka deformation elastic o ka mea hana he kumu nui no ka haʻalulu.Hoʻokaʻawale ka paʻi ʻoki ʻana i ka mea hana "elastic" mai ka mea hana a hoʻihoʻi hou, i ʻoi aku ka nui o ka friction ma waena o ka mea hana a me ka mea hana ma mua o ka hopena ʻoki.ʻO ke kaʻina hana friction kekahi e hoʻoulu i ka wela, kahi e hoʻonui ai i ka maikaʻi ʻole o ka wela o nā alloys titanium.
ʻOi aku ka paʻakikī o kēia pilikia i ka hana ʻana i nā ʻāpana me ka paia lahilahi a i ʻole ke ʻano apo i hiki ke hoʻololi ʻia.ʻAʻole maʻalahi ka mīkini ʻana i nā ʻāpana ʻāpana titanium me ka paia lahilahi i ka pololei o ke ana i manaʻo ʻia.Ke hoʻokuʻu ʻia ka mea hana e ka mea hana, ua ʻoi aku ka deformation kūloko o ka pā lahilahi ma mua o ka elastic range a hiki ke hoʻololi ʻia ka plastic, a piʻi nui ka ikaika a me ka paʻakikī o ka ʻokiʻoki.I kēia manawa, ʻoi aku ka kiʻekiʻe o ka wikiwiki o ka ʻoki i hoʻoholo mua ʻia, e hoʻopau hou i ka ʻoi o ka mea hana.
ʻO "Heat" ka "culprit" o ka titanium alloy paʻakikī ke hana!
2. Nā ʻōlelo aʻoaʻo no ka hana ʻana i ka titanium alloy
Ma ke kumu o ka hoʻomaopopo ʻana i ke ʻano hana o ka titanium alloy, i hui pū ʻia me ka ʻike ma mua, ʻo ka ʻike ʻenehana nui no ka hana ʻana i ka titanium alloy penei:
(1) Hoʻohana ʻia ka pahi me ka geometry kihi maikaʻi e hōʻemi i ka ikaika ʻoki, ʻoki i ka wela a me ka deformation mea hana.
(2) E mālama i ka hānai paʻa e pale i ka paʻakikī o ka mea hana.E noho mau ana ka mea paahana ma ke kulana hanai i ka wa e oki ai.ʻO ka nui o ka ʻoki radial ae i ka wā wili he 30% o ka radius.
(3) Hoʻohana ʻia ke kaomi kiʻekiʻe a me ka wai ʻoki kahe nui e hōʻoia i ka paʻa ʻana o ka wela o ke kaʻina hana, a pale i ka pōʻino o ka ʻili o ka mea hana a me ka pōʻino o ka mea hana ma muli o ka wela nui.
(4) E mālama i ka maka.ʻO ka mea hana blunt ke kumu o ka hōʻiliʻili ʻana o ka wela a me ka ʻaʻahu, e alakaʻi wale ana i ka hemahema o ka mea hana.
(5) E like me ka mea hiki, pono e hana ia i loko o ka palupalu o ka titanium alloy.I ka lilo ʻana o ka mea paʻakikī ma hope o ka paʻakikī, hoʻomaikaʻi ka mālama wela i ka ikaika o ka mea a hoʻonui i ka ʻaʻahu o ka maka.
(6) E hoʻohana i ka radius arc a i ʻole chamfer mea hana nui e ʻoki ai, a e hoʻokomo i nā lau he nui i loko o ka ʻokiʻoki.Hiki i kēia ke hoʻemi i ka ikaika ʻoki a me ka wela i kēlā me kēia wahi a pale i ka pōʻino kūloko.I ka wili ʻana i ka alloy titanium, he mana nui ka wikiwiki o ka ʻoki ʻana i ke ola o ka mea hana vc, a ukali ʻia e ka ʻoki radial (hohonu milling) ae.
3. E mālama i nā pilikia hoʻoponopono titanium mai ka maka
ʻO ke kāʻei ʻana o ka lau i ka wā o ka hana ʻana o ka titanium alloy ka lole kūloko o ke kua a me mua ma ka hohonu o ka ʻoki ʻana, ʻo ia ka mea i hana pinepine ʻia e ka papa paʻakikī i waiho ʻia e ka hana mua.ʻO ka hopena kemika a me ka laha ʻana o nā mea hana a me nā mea hana i ka mahana o ka hana ʻoi aku ma mua o 800 ℃ ʻo ia kekahi o nā kumu no ka hoʻokumu ʻana i ka lole groove.Ke hōʻiliʻili nei nā molekala titanium o ka mea hana i mua o ka lau i ka wā o ka hana ʻana, ua "welded" lākou i ka lau ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe, e hana ana i kahi puʻupuʻu chip buildup.Ke ʻili ʻia ka puʻupuʻu i kūkulu ʻia mai ka maka, e lawe ʻia ka uhi carbide cemented o ka maka.No laila, pono ka hana ʻana o ka titanium alloy i nā mea laulima kūikawā a me nā ʻano geometric.
