Whakaahuatanga Poto:

Whakaaturanga hua:

Heat Treatment-He tikanga e whakamahi ana i te whakamahana me te whakamatao ki te huri i nga ahuatanga o te tinana o nga putorino kohua teitei.Ka taea e te maimoatanga wera te whakapai ake i te microstructure o te ngongo kohua teitei, kia tutuki ai nga whakaritenga a-tinana e hiahiatia ana.Ko te uaua, te pakeke, me te whakakakahu he maha o nga taonga ka riro mai i te maimoatanga wera.Ki te whiwhi i enei ahuatanga, whakamahia te tiini & lt i te maimoatanga wera;ka karanga hoki tinei & gt;, tempering, annealing & lt;rewa & gt;me te whakapakeke o te mata, etc.

Ko te whakamaroke (te whakamaroke, e mohiotia ana ko te tinei) -ko te ngongo kohua teitei te whakamahana kia rite ki te pāmahana e tika ana, katahi ka rukuhia ki te wai, ki te hinu ranei i roto i te whakamahana tere, i te hau, i te waahi mīti ranei, kia whakamataohia te kohua teitei. ngongo ki te whiwhi i te pakeke e hiahiatia ana.
Ka pakarukaru te putorino kohu pehanga-teitei i muri i te tinei.I te wa ano, ko te ahotea na te tineia me te whakamatao ka pakaru te putorino paoho teitei ma te pupuhi marama.Hei whakakore i te pakaruhanga, ka taea te whakamahi i te tikanga maimoatanga whakamarumaru.Ko te whakamahana he whakamahana i te ngongo kohua teitei ki te pāmahana e tika ana, te tae ranei, katahi ka hoatu te makariri nui.Ahakoa he paku iti te pakeke o te putorino kohu pehanga teitei, ka taea e ia te whakanui ake i te uaua o te putorino kohua teitei me te whakaiti i tona pakaruhanga.
Ko te whakaene-annealing te tikanga ki te whakakore i te ahotea o roto me te maitai o te putorino kohua teitei.Ko te tikanga whakamahana ko te whakamahana i nga wahanga rino ki te wera nui, katahi ka maka ki roto ki te pungarehu maroke, kotakota, asbestos, katia ranei ki roto i te oumu, kia ata whakamatao.
Maamaa (Mardness) -ko te kaha o tetahi mea ki te aukati i te kuhu o waho.He tino tika te whakamatautau pakeke, he tikanga noa hei whakamatautau i te pakeke.Ko te tikanga whakamatautau e whakamahia nuitia ana ko te Rockwell hardness test Ka whakamahia e te miihini whakamatautau pakeke Rockwell te hohonutanga o te taimana i rere ki roto i te whakarewa ki te whakatau i te pakeke o te putorino kōhua ​​teitei, te nui o te hohonu o te kuhu, te iti ake o te pakeke.Ka tere te taimana ki te hohonutanga o te whakarewa hei tohu i te tau tika mai i te atatohu, e kiia nei ko te tau pakeke Rockwell.
Forging-ko te hama hei hanga i te whakarewa ki tetahi ahua & lt;niao & gt;tikanga, i te wa e whakawerahia ana te ngongo kōhua ​​pehanga teitei ki te pāmahana whakahiato, ka taea te mahi ki te hangai, ki te piko, ki te tuhi, ki te hanga me etahi atu mahi.Ko te nuinga o nga ngongo kohua teitei he ngawari ki te hanga ina whakamahana ki te whero here kanapa.
Britittleness-e tohu ana i te ahua o te putorino kohua teitei he ngawari ki te pakaru, he pakarukaru te rino maka, ka taka ki te whenua ka pakaru.He tata te hononga o te Britittleness me te pakeke, te pakeke o te 20 # putorino maitai te tikanga he pakarukaru hoki.
ductility- (e mohiotia ana ano ko te ngawari) ko te ahua o te whakarewatanga mau tonu na te kaha o waho me te kore he wehenga, ka taea te kumea te paipa o te putorino pehanga teitei ki nga raina kikokore.
Elastic-he taonga o te ngongo kohu pehanga teitei kua whakahekehia e te kaha o waho, ka whakakorehia te kaha o waho.Ko te maitai o te puna he mea tino rapa.
Ko te pakeke-ko te aukati whakarewa ki te werohanga o waho, ki te tapahi ranei ka taea te whakanui ake i te pehanga teitei o te kohuatanga ngongo pakeke ko te tinei tikanga.
Mahinga- -e mohiotia ana ko te malleability, he tohu ano mo te ngawari me te ngawari.Ko te whakaaturanga he taonga mo te whakarewa i te hama te hanga, te huri ranei.
Ko te uaua ko te kaha o te putorino kohua teitei ki te tu ki te wiri, ki te paahitanga ranei.Ko te uaua he rereke noa iho o te pakarukaru.
I roto i te tukanga whakaputa o te putorino maitai mo te kōhua, maimoatanga wera ko te tukanga matua.Ko te maimoatanga wera he paanga nui ki te kounga o roto me te kounga o te mata o te putorino maitai kore, he mea tino nui mo te hanga o te putorino koranu maitai.
Ka whakamahia e to taatau kamupene te maimoatanga wera kore-haora, te hanga paipa rino me te whakahaere metallographic pumau me te pai o te kounga o roto, o waho hoki, ma te whakamahi i te eddy o naianei me te ultrasonic aunoa i te rapu koha, te paipa rino tetahi mo te koha o naianei eddy me te koha ultrasonic.Ma te inenga matotoru ultrasonic me nga mahi whakakitenga koha, ka taea e ia te kite i nga hapa o te paparanga i roto i te paipa maitai.
