Koranu maitai

I roto i te kōwhiri i te rauemi mo te hanga o ngā hua whakarewa e rave rahi ngā āhuatanga ki te kia whakaaro, tae atu i te uara tawhiti o rigidity. Tei tēnei taupū kiriuka hanganga anake i runga i te āhua o te rauemi i nei te mea timatanga mana - stringers, papa, papa paraharaha, flat, me ētahi atu

Ko te uara tawhiti teitei o te rigidity he parahi, i roto i te tahuri ko e o rua ngā momo i roto i to ratou hanganga matū. Tuatahi, tenei parahi koranu, e āta honoa huānga alloying ki te whiwhi i tetahi āhuatanga e tika ana.

Ko te āhuatanga matua e whakaawe nga āhuatanga o te maitai - he waro, silicon me te konupora. Waro i te whakanui ake i tona ihirangi hanga te parahi kaha me uaua, i te whakaiti i tona te kōngohe. whakahaere Silicon te rite te kaihoko deoxidizing, engari ki te he tona ihirangi neke atu i te kotahi ōrau nui ino roa te weldability o maitai: he pakarukaru te Weld. A ko te pūmotu rite te konupora whakapiki i brittleness matao, me te taikaha o te parahi, ano he deoxidizer pai.

Tikanga, i roto i te tua ki te rino, me te waro, te tāpiri ki tētahi wae kotahi, kia patu maitai whakarōpūtia rite te toru-wae,-wae wha, a na i runga i. D. taime rerekē reira mo te taitara o te huānga alloying, pērā i chromium, chromium-nika, etc. hromonikelmolibdenovaya

Koranu maitai Kei neke atu i te kotahi ōrau o te chromium konukoreko ranei. Ki te he te reira i roto i neke atu i te 0.5% o te vanadium, Titanium, molybdenum, Niobium, hauota, parahi, me ētahi atu, Kei te whakaaro te reira e enei huānga koranu.

Tei runga i te maha o ngā wāhanga tāpiri, e tahuri iho koranu maitai ki te subclasses e whai ake nei:

- tiketike-koranu maitai, ai te ihirangi katoa o ngā āhuatanga alloying he iti iho i te kotahi tekau ōrau;

- srednelegirovannoj - kaua e nui ake waru ōrau;

- maitai, i roto i nei te tapiritia kotahi anake huānga ki te tirotiro o te rohe o runga o te kore ake atu i te rua ōrau iti-kongatia.

Tikanga, nga mea timatanga alloying nui ake i te utu o te parahi, rawa mai e tapiritia etahi huānga i roto i he ratou hapa konganuku utu. Fakatatau ki ai, Me āta tūāpapa ratou tua ki te parahi.

He nga tohu e whai ake nei patu maitai: te mati tuatahi e rua tohu te ihirangi waro (haurau o te ōrau), te pukapuka tohu herenga tāpiri alloying huānga mati i muri ia ratou - te ihirangi o tenei huānga rite te ōrau. Ko te reta "A", e tu i te mutunga o nga tikanga tohu, e te parahi kounga tiketike ki te ihirangi iti o te ūkuikui me te whanariki.

Ko tetahi rerenga o te hanganga matū o te maitai - waro. Ko tōna no o te tapatahi, me te cheapness o production piki whakamahia i roto i te ahumahi maha.

Ko tētahi o te whakamahi tikanga o te parahi, ko tona whakamahi i roto i te hanga o te ine, me te tapahi taputapu, wahi mīhini, mate ki te deformation matao, me te wera.

Taputapu maitai me te take koranu, me te waro, ko i runga i te ture faaterehia e te āheinga, mo ia hua maitai motuhake rānei e ki te whakamahi i maitai he hanganga matū motuhake.

. Hei tauira, mō ngā taputapu hāparapara, ngā akoako, whao, hama, screwdrivers, kani, hobs, me ētahi atu whakamahia maitai kāwai ngā - nui-koranu, tiketike-tere. He pakeke tiketike, resistance wera me te abrasion resistance. E whiwhi ēnei āhuatanga ahurei mā te tāpiri alloying motuhake ki Tungsten carbide, me te maimoatanga wera uaua.

Hoki te hama, mate wera me te makariri, pakete me al. Kōeke maitai whakamahia pērā i H6VF, 9X, 5HNM etc.
