Ko te pānga o te mātotoru o te karāhe ki te mahi a te hikohiko e whakaatahia ana i roto i ngā āhuatanga e whai ake nei:
- Te Kaha Mīhini me te Porosity
- He hononga pai i waenga i te mātotoru me te kaha ā-pūkaha: Mā te whakanui ake i te mātotoru o ngā irahiko karāhe ka whakaiti i te porosity me te whakarei ake i te kaha ā-pūkaha. Ka pai ake te tu atu o ngā irahiko mātotoru teitei ki ngā pānga o waho me ngā ahotea wera i te wā e whakarewahia ana te oumu pewa hiko, e miihini tuku hiko rānei (EDM), ka whakaiti i ngā mōrearea pakaru, pakaru rānei.
- Te Pānga o te Porowhita: Ko ngā irahiko iti-kiato, he porowhita nui, ka ngāwari ki te uru koretake ki te irahiko, ka tere ake te pakaru o te irahiko. He rerekē, ka roa ake te ora o ngā irahiko nui-kiato mā te whakaiti i te porowhita.
- Ātete Waikura
- He hononga pai i waenga i te mātotoru me te ātete waikura: He hanganga tioata matotoru ake ngā irahiko karāti mātotoru, e ārai ana i te urunga o te hāora me te whakaroa i ngā tere waikura. He mea nui tēnei i roto i ngā tukanga whakarewa pāmahana teitei, i ngā tukanga hiko rānei, e whakaiti ana i te whakamahinga o ngā irahiko.
- Tauira tono: I roto i te hanga maitai o te oumu pewa hiko, ka whakaitihia e ngā irahiko kiato teitei te whakaiti i te diameter i puta mai i te waikura, kia mau tonu ai te pai o te kawe iahiko.
- Te Ātete ki te Ru Wera me te Arahi Wera
- Te tauwhitinga i waenga i te mātotoru me te ātete ki te ru wera: Mā te mātotoru nui rawa ka whakaiti i te ātete ki te ru wera, ka piki ake te ngawari ki te pakaru i raro i ngā huringa pāmahana tere. Hei tauira, i roto i te EDM, ka whakaatuhia e ngā irahiko iti-mātotoru te pumau nui ake nā te iti o te tauwehenga whānui wera.
- Ngā mahi arotau: Mā te whakarei ake i te kawe wera mā te whakanui ake i te pāmahana whakapūkara (hei tauira, mai i te 2800°C ki te 3000°C) mā te whakamahi rānei i te ngira kōka hei rauemi mata hei whakaiti i te tauwehenga whānui wera ka taea te whakapai ake i te ātete ki ngā ru wera me te pupuri tonu i te kiato teitei.
- Te Arahi Hiko me te Āheitanga Mīhini
- Te mātotoru me te kawe hiko: Ko te kawe hiko o ngā irahiko karāpeti e whakawhirinaki ana ki te hanganga o te tioata, kaua ki te mātotoru anake. Heoi, ko ngā irahiko mātotoru teitei e tuku ana i ngā ara iahiko ōrite ake nā te iti o te porosity, ka whakaiti i te wera nui o te rohe.
- Te Āhuatanga Mīhini: He ngawari ake, he māmā ake hoki te mīhini i ngā irahiko karāhe iti-kiato, ā, e 3–5 ngā wā tere ake te tere tapahi i ngā irahiko parahi, ā, he iti rawa te mau o ngā taputapu. Heoi, he tino pai ngā irahiko nui-kiato ki te pumau o ngā āhuatanga i te wā e mīhini tika ana.
- Te Maukati o te Irahiko me te Whai Huatanga Utu
- Te mātotoru me te tere o te pakaru: Ka hangaia e ngā irahiko mātotoru teitei he paparanga tiaki (hei tauira, ngā matūriki waro piri) i te wā e tukatuka ana i te whakarewanga, hei utu mō te pakaru me te whakatutuki i te "kore pakaru" te pakaru iti rānei. Hei tauira, i roto i te EDM o ngā wahi mahi maitai waro, ka taea e tō rātou tere pakaru te 30% te iti iho i tērā o ngā irahiko parahi.
- Tātaritanga utu-painga: Ahakoa te nui ake o ngā utu mō ngā rauemi mata, ka whakaitihia e ngā hikohiko kiato-nui ngā utu whakamahinga whānui nā te roa o te ora me te iti o te pakaru, inā koa i roto i te miihini pokepokea nui.
- Arotau mō ngā Taupānga Motuhake
- Ngā ānode pākahiko lithium-ion: Ko te mātotoru o ngā ānode graphite (1.3–1.7 g/cm³) ka pā tika ki te mātotoru o te pūngao pākahiko. Ka ārai te mātotoru nui rawa o te ānode i te hekenga o te katote, ka whakaiti i te tere o te mahi, engari ka whakaitihia te kawe hiko e te mātotoru iti rawa. Me whakatauira te rahi o te matūriki me te whakarerekē i te mata hei whakataurite i te mahi.
- Ngā kaiwhakatikatika irahiko i roto i ngā tauhohenga karihi: Ka arotau te karapiti kiato-teitei (hei tauira, te kiato ariā o te 2.26 g/cm³) i ngā wāhanga whakawhiti marara irahiko, ka whakarei ake i te whai huatanga o te tauhohenga karihi me te pupuri tonu i te pumau matū.
