Kāhea ʻia ka forgingka hana ana, he kaomi oke kalaiwa ananā mīkini no ka poloka metala, hana i kāna huahana plastic deformation, i loaʻa kekahi mau waiwai mechanical, kahi ʻano a me ka nui oke kalaiwa anahe hana hana, heke kalaiwa ana (ke kalaiwa ana) ʻo ia kekahi o nā mea nui ʻelua,hoʻopunipunihiki iā ia ke wehe i ke kaʻina hana hoʻoheheʻe metala o nā hemahema e like me ka wehe ʻana, ʻoi aku ka maikaʻi o nā waiwai mechanical o ka hoʻoheheʻe ʻana ma mua o nā mea hoʻoheheʻe o ka mea like ma muli o ka microstructure i hoʻopaʻa ʻia a me ka pololei o ka streamline metala.

Ma ka ultrasonic conditioning lapaʻau onā kalaiwae hoʻokō ʻia ma hope o ka mīkini paʻakikī, ʻo ka propeller shaft material he mea maʻamau 34 crmol steel, kona hardenability, kiʻekiʻe hopena hana koi, a me ka ikaika o ke koi ʻoi aku ka kiʻekiʻe, ʻoiai e hōʻoiaʻiʻo ana i ka ikaika kiʻekiʻe i ka manawa like, paʻakikī ke hālāwai. nā koi o ka hopena onā kalaiwaka lōʻihi loa, ke kaumaha, a me ke kuʻi ma mua o ka mālama ʻana i ka wela, maʻalahi ka hiki ʻana o ka deformation mālama wela, maʻalahi ka hana ʻana i ka wela i ka wā e kulou ai ka deformation, pēlā e hoʻonui ai i ka paʻakikī o ka hoʻopau ʻana i ka mea hana, e kāohi i ka deformation lapaʻau wela, ke ʻano o ka lua kūpaʻa e kau ana. hoʻomaʻalili i ka umu ahi, ka wai i hoʻoluʻu ʻia ma o nā mea hana i ke ahi, ka aila anu ma o nā mea hana e pili ana i ke ahi, i ka wā e pale ai i ka paʻakikī e kinai ana i ka pohā a pohā i loko o ke ahi, nā waiwai mechanical o hoʻokahi-manawa kūpono huahana, e hoʻomohala i ke anuanu ea hoʻoluʻu + wai + aila kaʻina hana.
ʻO ka mea i luna nei kekahi o nā ʻokoʻa ma waenake kalaiwa anaake kalaiwa ana. Hiki iā mākou ke aʻo e pili ana iā ia. Inā he mau nīnau kāu a me nā pono, hiki iā ʻoe ke waiho pololei i kāu mau pono a me ka ʻike pili ma ka pūnaewele.
