Hoʻopilikiaʻia Hardening

Hoʻopilikiaʻia Hardening he kaʻina hana hoʻomehana i ukali ʻia e ka maʻalili maʻamau no ka hoʻonui ʻana i ka paʻakikī a me ka ikaika mechanical o ke kila.

No kēia hopena, hoʻomehana ʻia ke kila i kahi mahana i ʻoi aku ka kiʻekiʻe ma mua o ka mea koʻikoʻi kiʻekiʻe (ma waena o 850-900ºC) a laila hoʻomaʻalili ʻoi aʻe a liʻiliʻi paha (e pili ana i nā ʻano o ke kila) i loko o kahi mea e like me ka aila, ka ea, ka wai, ka wai. hui pū ʻia me nā polymers soluble, etc.

Aia nā ʻano hana like ʻole no ka hoʻomehana ʻana e like me ka umu uila, ka mea kuke ʻea, ka paʻakai, ka lapalapa, ka induction, etc.

ʻO nā kila i hoʻohana mau ʻia i ka paʻakikī induction mai ka 0.3% a i ka 0.7% carbon (hypoeutectic steels).

ʻO ka hoʻolālā hoʻokūkū pono:

  • Mālama ia i kahi ʻāpana kikoʻī o ka ʻāpana (hoʻopaʻa paʻakikī)
  • Hoʻomalu pinepine a me nā manawa wela
  • Mana hoʻomālili
  • Ke ikehu ana
  • ʻAʻohe pili kino
  • Hoʻomalu a loaʻa ka wela
  • Hiki ke hoʻohui i nā laina hana
  • Hoʻonui i ka hana a mālama i ka lewa

Hiki ke hana ʻia ka paʻakikī induction ma nā ʻano ʻelua:

  • Kūpaʻa: ʻO ka hoʻonohonoho ʻana i ka ʻāpana i mua o ka inductor a me ka hoʻokō ʻana i ka hana me ka ʻole o ka neʻe ʻana i ka ʻāpana a i ʻole ka inductor. He wikiwiki loa kēia ʻano hana, koi wale i nā mechanics maʻalahi a hiki i ka localization pololei loa o ka wahi i mālama ʻia, ʻoiai me nā ʻāpana me ka geometry paʻakikī.

  • Holomua (ma ka nānā ʻana): ʻo ia ka hele ʻana ma luna o ka ʻāpana me ka hana mau, ka neʻe ʻana i ka ʻāpana a i ʻole ka inductor. ʻO kēia ʻano hana ʻo ia ka hiki ke mālama ʻia nā ʻāpana me nā ʻili nui a me nā nui nui.

No ke ʻano like o ka ʻāpana e koi ai ka mālama scanning i ka mana liʻiliʻi me ka manawa lapaʻau lōʻihi i ka hoʻohālikelike ʻia me ka mālama ʻana.

ʻO ka hoʻohaʻahaʻa ʻana

ʻO ka hoʻohaʻahaʻa ʻana he kaʻina hana hiki ke hoʻemi i ka paʻakikī, ikaika a hoʻonui i ka paʻakikī o nā kila paʻakikī, ʻoiai e hoʻoneʻe i nā ʻāʻī i hana ʻia i loko o ka luakini, e waiho ana i ke kila me ka paʻakikī i koi ʻia.

ʻO ka ʻōnaehana hoʻoheheʻe kuʻuna maʻamau ka hoʻomehana ʻana i nā ʻāpana ma kahi haʻahaʻa haʻahaʻa (mai 150ºC a 500°C, ma lalo mau o ka lainaAC1) no kekahi manawa a laila e hoʻomaha mālie.

Loaʻa nā pono hoʻomehana induction:

  • ʻO nā manawa pōkole i ke kaʻina hana
  • ʻO ke kaohi o ka pale
  • Hoʻohui i nā laina hana
  • Ke ikehu ana
  • Loaʻa koke i nā ʻāpana
  • Mālama i ka papahele papahele
  • Hoʻomaikaʻi ʻia nā kūlana kaiapuni

ʻO ke kaʻina hana o ka paʻakikī a me ka hoʻomaʻamaʻa ʻana he lāʻau lapaʻau no nā ʻāpana like ʻole i nā ʻāpana ʻoihana.
