Te tātari tono o te pepa bimetallic i roto i te whakamarumaru wera

2022-03-01

Ko te mea tino nui i roto i tewhakamarumaru werako te bimetal. I tenei ra, ka kawea koe e ahau ki te mohio ki te whakamahinga o te bimetal i roto i te whakamarumaru wera.

Ko te mahi a te pepa bimetal i roto i te whakamarumaru waiariki ko: ka huri te pāmahana, na te mea he nui ake te whakarea roha o te taha roha teitei o te bimetal i te whakarea roha o te taha roha iti, ka puta te piko, ka whakamahia e matou tenei piko. mahi. i roto i tewhakamarumaru wera.

He rite tonu nga rauemi mata bimetallic wera o nga momo kaihanga, ko te matrix he rino me te koranu parahi, ka taapirihia nga huānga penei i te nickel me te manganese ki te whakarereke i o raatau whakarea roha, ka puta mai he koranu taha toronga teitei me te taha whakaroa iti, a katahi te titonga hiato. I etahi wa ka taapirihia nga koranu matua hei whakarereke i te parenga o te rauemi.

I mua i te whakaemi i tewhakamarumaru wera, Ko te hanga pepa bimetallic he mahi tino nui. Tuatahi, ka werohia te riu wera bimetallic, ka paratea kia rite ki te ahua o te pepa, katahi ka hanga i mua hei ahua kōpae. I tenei wa, ko te bimetal waiariki te ahua o te rihi he mahi pumau me te tautuhi i te pāmahana. Ko nga tawhā matua o te bimetals e tika ana kia whakaarohia i mua i te werohanga: te piko motuhake, te whakanekehanga rapa, te pakeke, te tika o te ahu, te parenga, te awhe pāmahana whakahaere. Tuatahi whakaarohia te awhe mahana ka taea te whakamahi i te pepa bimetal, katahi ka whakaarohia te kaha me te taipana o te hohenga ka mahia e te bimetal, ka kowhiri i te whakapiko tauwhāiti me te kōwae rapa. Kātahi ka tohua te rahi, te pakeke me te kōwae rapa o te bimetal wera e tika ana mo te mahi whakaniko me nga taputapu. Na ka kowhiri i te parenga e tika ana kia rite ki nga whakaritenga o te waa o naianei o te kaiwawao me te paanga o te kohao kaha wera.

E ai ki te tauira huanga waiariki o naianei Q=∫t0I2Rdt, ka taea te mohio ko te kowhiri i te bimetal he nui te parenga ka nui ake te wera, ka whakapoto i te wa mahi o te whakamarumaru waiariki, me te whakaiti i te iti o te waa whakahaere. Ko te ritenga ke mo nga bimetal he iti te parenga. Ko te parenga o te bimetal ka pa ki te parenga, te rahi me te matotoru o te ahua.
