Ka Mana o ka Oki Wela
I ka wili ʻana i nā ʻāpana nickel-based, nui ka nui o ka ʻoki ʻana i ka wela. No laila, i ka hana ʻana i ka mīkini, e hoʻopili i ka mea hoʻomaʻamaʻa lawa e hoʻohaʻahaʻa i ka wahi ʻokiʻoki, maʻalahi ke hoʻokō ʻia no nā mea ʻoki wili liʻiliʻi, akā no nā mea hana nui-anawaena (e like me nā mea ʻoki wili maka), ʻaʻole hiki ke hoʻopau piha i ka wā e ʻoki ai, a hiki ke ho'opau wale 'ia ka mea ho'oma'ama'a, me ka wili malo'o.
Ke hiki ʻole ke uhi ʻia ka mea ʻoki wili e ka mea hoʻoluʻu, hoʻoneʻe koke ʻia ka wela i ka hoʻokomo ʻana, e hopena i nā māwae liʻiliʻi he nui e kū pono ana i ka ʻoki ʻoki, a hoʻonui mālie nā māwae, a laila e haki ai ka carbide sima. I kekahi mau hihia, hiki ke hoʻohana ʻia kahi mea ʻoki liʻiliʻi liʻiliʻi, a ʻaʻohe mea hoʻomaha e koi ʻia no ka mīkini. Inā ʻoki maʻamau ka mea hana a hoʻomaikaʻi ʻia ke ola o ka mea hana, ʻo ia ka mea hiki ke hana ʻia ka wili maloʻo maikaʻi.
No ka mea, ua hana pinepine ʻia nā ʻāpana o ka lāʻau lapaʻau a me nā ʻoihana aerospace me nā nickel-based alloys, ua hui pū ʻia kēia mea me nā palapala hōʻoia, kahi i hāʻawi ʻia ai ke ʻano kemika o kēia mea kūikawā, i hiki iā mākou ke ʻike i ka wā e wili ai ka wili. he aha ka mea. ʻO ka mea e pono e hoʻolohe ʻia pehea e koho ai i nā palena ʻoki kūpono a me nā ʻano ʻokiʻoki e like me ke ʻano o ia mau mea.
E like me ka mea i ʻōlelo mua ʻia, ʻo nā mea nui ʻelua o kēia pūʻulu metala ʻo nickel a me chromium. Ke hoʻololi ka mea hoʻoheheʻe metala i ka pākēneka o kēlā me kēia metala, hoʻololi kona mau waiwai e like me ke kūpaʻa corrosion, ikaika, paʻakikī, a me nā mea ʻē aʻe, e like me kona machinability.
ʻAʻole paʻakikī ka hoʻolālā ʻana i kahi mea hana e ʻoki ai i nā mea hana paʻakikī, akā ʻaʻole paʻakikī ka hoʻolālā ʻana i kahi mea hana nickel-based alloy e hana i nā mea ʻelua. Loaʻa paha iā ʻoe kou inoa ponoʻī no kēia mau alloys, akā inā ʻike ʻoe i kā lākou haku mele ʻana a hoʻohana i ka mea paahana kūpono, hiki iā ʻoe ke wili i nā mea e like me Corp20, Rene41, a me Haynes242 me ka ʻole o ka pilikia.
