He aha ka Carburizing & Nitriding

Hoʻoheheʻe Vacuum me Acetylene (AvaC)

ʻO ke kaʻina hana carburizing vacuum AvaC kahi ʻenehana e hoʻohana ana i ka acetylene e hoʻopau loa i ka pilikia o ka soot a me ke tar i ʻike ʻia e kū mai ana mai ka propane, me ka hoʻonui nui ʻana i ka mana carburizing no ka makapō a i ʻole ma o nā lua.

ʻO kekahi o nā pono nui o ke kaʻina hana AvaC ʻo ia ka loaʻa ʻana o ke kalapona kiʻekiʻe, e hōʻoiaʻiʻo ana i ka carburizing homogenous loa no nā geometries paʻakikī a me nā densities ukana kiʻekiʻe loa. Pili ka hana AvaC i ka injection ʻokoʻa o ka acetylene (boost) a me kahi kinoea neutral, e like me ka nitrogen, no ka diffusion. I ka wā o ka injection boost, e hoʻokaʻawale wale ka acetylene i ka wā e pili ana me nā ʻili metala āpau e ʻae ai i ka carburizing like.

ʻO ka pōmaikaʻi kupaianaha loa iā AvaC hiki ke loaʻa i ka wā e loiloi ʻia ai nā kinoea hydrocarbon like ʻole no ka carburizing haʻahaʻa haʻahaʻa no ko lākou mana komo i loko o nā lua liʻiliʻi, lōʻihi, a makapō. ʻO ka carburizing vacuum me ka acetylene ka hopena o ka carburizing piha ma ka lōʻihi holoʻokoʻa o ka lua no ka mea he ʻokoʻa loa ka hiki ke carburizing o ka acetylene ma mua o ka propane a i ʻole ethylene.

Nā pono o ke kaʻina hana AvaC:

Ka hiki ke hoʻomau i ka hoʻopuka kiʻekiʻe

Ka hana hou ʻana i hōʻoia ʻia

Ka hoʻolaha ʻana o ke kinoea acetylene maikaʻi loa

ʻŌnaehana modular hāmama, mālama pono

Hoʻonui ʻia ka hoʻoili kalapona

Hoʻemi ʻia ka manawa hana

Hoʻomaikaʻi ʻia ka microstructure, hoʻonui i ke kūpaʻa koʻikoʻi, a me ka maikaʻi o ka ʻili o nā ʻāpana

Ka hoʻonui waiwai no ka hoʻonui ʻana i ka mana

Nā ʻano hana hoʻopau like ʻole me ka helium, ka naikokene, nā kinoea i hui ʻia, a i ʻole ka ʻaila

Nā pono ma luna o nā umu lewa:

ʻOi aku ka maikaʻi o ka hana me ka hoʻolālā paia anu, e hāʻawi ana i ka mahana o ka pūpū haʻahaʻa

ʻAʻohe pono o nā ʻūpā hoʻopau pipiʻi a i ʻole nā ​​puʻu

Hoʻomaka wikiwiki a me nā pani ʻana

ʻAʻole koi ʻia nā mea hana kinoea endothermic

ʻOi aku ka liʻiliʻi o ka papahele e pono ai nā umu kinai kinoea a ʻaʻohe holoi ma hope e wehe i nā aila kinai

ʻAʻohe lua a i ʻole nā ​​​​koi kumu kūikawā e pono ai

Ka hoʻoheheʻe ʻana i ke kalapona

He hana hoʻopaʻakikī hihia ka Carbonitriding e like me ka carburizing, me ka hoʻohui ʻana o ka naikokene, i hoʻohana ʻia e hoʻonui i ke kūpaʻa ʻana o ka ʻaʻahu a me ka paʻakikī o ka ʻili. Ke hoʻohālikelike ʻia me ka carburizing, ʻo ka hoʻolaha ʻana o ke kalapona a me ka naikokene e hoʻonui i ka paʻakikī o ke kalapona maʻemaʻe a me nā kila alloy haʻahaʻa.

ʻO nā noi maʻamau e komo pū me:nā kia a me nā ʻauamonā pistonnā wili a me nā bearingsnā levers i loko o nā ʻōnaehana hydraulic, pneumatic a me mechanical.

Hoʻohana ke kaʻina hana carbonitriding haʻahaʻa (AvaC-N) i ka acetylene a me ka ammonia. E like me ke carburizing, he ʻāpana paʻakikī ka ʻāpana hopena, kūpaʻa i ke komo ʻana. Eia naʻe, ʻaʻole like me ke carburizing AvaC, ʻo ka hohonu o ka nitrogen a me ke kalapona ma waena o 0.003″ a me 0.030″. ʻOiai ʻo ka nitrogen e hoʻonui i ka paʻakikī o ke kila, hana kēia kaʻina hana i nā ʻāpana me ka paʻakikī i hoʻonui ʻia i loko o ka hohonu o ka hihia i hōʻike ʻia. ʻOiai ʻo ka carbonitriding e hana ʻia ma nā mahana haʻahaʻa iki ma mua o ka carburizing, hoʻemi pū ia i ka distortion mai ka quenching.

Ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana i ka nitrocarburization

ʻO ka Nitriding kahi hana hoʻopaʻakikī e hoʻolaha i ka naikokene i loko o ka ʻili o kahi metala, ʻo ka hapa nui he mau kila haʻahaʻa-kalapona, haʻahaʻa-alloy. Hoʻohana ʻia nō hoʻi ia ma nā kila kalapona waena a me ke kiʻekiʻe, titanium, alumini a me ka molybdenum.

ʻO ka Nitrocarburizing kahi ʻano papau o ke kaʻina hana nitriding kahi e hoʻolaha ai ka naikokene a me ke kalapona i loko o ka ʻili o ka ʻāpana. ʻO nā pono o ke kaʻina hana e pili ana i ka hiki ke hoʻopaʻakikī i nā mea ma nā mahana haʻahaʻa e hōʻemi ana i ka distortion. He haʻahaʻa hoʻi ke kumukūʻai i hoʻohālikelike ʻia me ka carburizing a me nā kaʻina hana paʻakikī ʻē aʻe.

ʻO nā pono o ka Nitriding a me Nitrocarburizing e komo pū me ka ikaika i hoʻomaikaʻi ʻia a me ke kūpaʻa ʻana i ka ʻaʻahu a me ka palaho.

Hoʻohana ʻia ka Nitriding a me ka nitrocarburizing no nā kia, nā wili, nā pūnāwai, nā crankshafts a me nā camshafts, a me nā mea ʻē aʻe.

Manaʻo ʻia nā umu no ka carburizing a me ka nitriding.
