He aha keʻano o ka mea kila paʻakikī paʻakikī?
ʻO ka paleʻana i ka mea kila paʻakikī, pinepine i kapaʻiaʻo ia e like me ka "ph retainless kila," heʻanoʻano mea hoʻokūkū i kapaʻia heʻano paʻakikī a iʻole ka paʻakikī. Hoʻopili kēia kaʻina i nā mea hana mechanical o nā mea o ka waiwai,ʻo ia ka ikaika a me ka paʻakikī. ʻO ka mea maʻamau maʻamau maʻamauʻo ia17-4 p p ph(Astm A705 SILER 630), akā, e like me nā mea'ē aʻe he 15-5 ph, e hāʻule pū me ka chopuahi ʻO ka hoʻohuiʻana o kēia mau mea hoʻohui hoʻohui i nā hana i ka hoʻokumuʻana o nā mea hana i ka wā o ke kaʻina hana wela.
Pehea ka paʻakikī o ka hoʻomaʻamaʻaʻana i nā kila kila?
ʻO nā makahiki paʻakikī paʻakikī e pili ana i keʻano o ke kaʻina hanaʻekolu. I ka manawa mua,ʻo ka mea i hoʻohanaʻia i kahi o ka hopena o ka hopena kiʻekiʻe, kahi e hoʻopau ai nā atoms i kahi o nā mea hana. Ke alakaʻi nei kēia i ka hoʻokumuʻana o nā microscopic numacopic nulei a iʻole "zones" i ka metala. Ma hope aku,ʻo REPID e hele ana ma mua o ka palena palena kūpono, e hana ana i kahi hopena maikaʻi loa i kahiʻano hope loa A laila e mālamaʻia ka mea i kēia moku'āina a hiki i ka wā e hoʻopaʻaʻole ai. Pono ke kūleʻa o ka hana kūleʻa i ka hoʻohuiʻana o ka alloy
He aha nāʻano o nā mea kila paʻakikī paʻakikī?
Ua hele mai nā hele wāwae o ka hana i nāʻano likeʻole, i kēlā me kēia hana e hoʻokō i nā koi a me nā koi. Loaʻa nāʻano maʻamau he 17-4 PH, 15-5 pr, 13-8 PH, 176, Kūʻai 43017-4 p p phMod), a me ke kākela e kūʻai aku ai i nā kilokilo 455.ʻO kēia mau mea hoʻohālikelike e like me keʻano o ka ikaika. ʻO ke koho no ka mea kila i hiki ke kau i nā mea hana e like me nā mea noi e like me nāʻenehana noi, hanaʻana i nā lako hana, a hana i nā mea hana.
POHE:
1. He mea nui loa ka packing i kahi hihia o nā moku honua ma kahi e hele ai i nā wahi kūpono e hiki ai iā mākou ke kau aku i ka manaʻo kūikawā
2.ʻO ka pahu o ka steel steel i kā mākou mau huahana i nā ala nui e pili ana i nā huahana. Mālama mākou i kā mākou huahana ma nā ala he nui, e like me,
