Whakaahuatanga taipitopito

Ko nga toromoka kaha teitei ka whakaputa i te kirikiri ina piauau. Me aro motuhake.

Ko te kaha o te hauhautanga he tohu na te roa o te pakaru i raro i te ahotea. He puna motopaika, horoi, wiri, puna puna me etahi atu waahanga piauau, i roto i etahi haora i muri i te pakaru o te huihuinga, ko te wehenga pakaru o te 40% ~ 50%. I roto i te whakamahi i nga waahanga kua whakakikoruatia ki te cadmium o tetahi hua motuhake, ka pakaru te puranga, ka whakatauhia he raruraru matua o te motu, ka hangaia he tukanga whakaheke wai. I tua atu, i reira e te tahi mau hauwai embrittlement e kore e whakaatu i te ahua pakaru roa, penei: te iri hiko (waea maitai, waea parahi) na te maha o nga wa o te whakakikorua me te whakakikorua, he nui ake te kino o te urunga hauwai, he maha nga wa ka puta mai i roto i te whakamahi he kopaki ka puta nga ahuatanga pakaru pakaru; Ko te mandrel o te pu, he maha nga wa o te chroming, ka taka ki te whenua, ka pakaru; Ko etahi waahanga kua tineia (he ahotea nui o roto) ka pakaru i te wa e piro ana. Ko enei waahanga ka kaha te hauwai, ka ngatata me te kore he taumahatanga o waho, ka kore e taea te whakamahi ki te whakahoki mai i te pakaritanga taketake na roto i te whakahekenga wai.

Ko te teitei ake o te kaha rawa, ka nui ake te kaha o te hauwai. He ariā taketake tenei me whakamarama e nga tohunga hangarau maimoatanga mata i te wa e whakahiato ana i nga whakaritenga o te tukanga hiko. Ko nga tira me te kaha kaha σb> 105kg/mm2 e hiahiatia ana e nga paerewa o te ao, me tukuna ki te ahotea o mua i te whakakikorua me te maimoatanga whakaheke i muri i te whakakikorua. Ko te ahumahi rererangi French e hiahia ana kia rite ki te maimoatanga whakaheke wai mo nga waahanga rino me te kaha tuku σs>90kg/mm2.

Na te pai o nga reta i waenga i te kaha rino me te pakeke, he pai ake te mohio me te watea ki te whakatau i te kaha o te hauwai o te rauemi ma te pakeke atu i te kaha. Na te mea me tohu te tuhi hua tino pai me te mahi miihini ki te pakeke rino. I roto i te whakakikorua hiko, i kitea e matou ko te pakeke o te maitai huri noa i te HRC38 i timata ki te whakaatu i te tupono o te pakaru o te hauwai. Mo nga waahanga teitei ake i te HRC43, me whai whakaaro te whakahekenga wai i muri i te whakakikorua. A, no te pakeke e pā ana ki te HRC60, me whakahaere te maimoatanga dehydrogenation i muri tonu i te maimoatanga o te mata, ki te kore ka pakaru nga waahanga rino i roto i etahi haora.
