E whakamahia whānuitia ana te rino puta noa i te ao nā te mea he pai te utu, ā, he taurite hoki ngā āhuatanga o te rauemi. Engari mō te maha o ngā hua, kua taumaha kē te rino he 7.8 karamu/henimita kūpiko te matotoru. I tēnei wā, me rapu ngā kaihoahoa i ētahi atu rauemi hei whakaiti i te taumaha. Ahakoa ka taea e ngā kirihou te whakaiti i te taumaha, he ahurei te rongonui me te kaha o ngā konganuku mama.
Ko ngā konganuku māmā me ngā koranu pēnei i te konumohe, te titanium me te konupora ka whakakapi i te maitai i roto i te hoahoa hua. Hei āwhina i te aromatawai i a rātou, ka'kua kohikohia e au tētahi kōrero poto e matapaki ana i ngā painga, ngā huakore me ngātono noaMā te whakataurite i ngā āhuatanga o ia rauemi ka āwhina i ngā whakatau hoahoa hua.
#1 Titanium – 42% te mama ake i te maitai
He rauemi koranu tino kaha, he pakari hoki, ko te titanium te mea tino kaha i roto i ngā momo rauemi whakarewa katoa, ā, he nui tōna kaha ki te tū hei tuatahi. Haunga tōna kaha tino pai, he tino pai hoki te ātete ki te waikura me te pumau i roto i ngā taiao pāmahana teitei. Nā tōna hototahi koiora pai, he whānuitia te whakamahinga o te titanium i roto i ngā momo taputapu hauora e hiahia ana kia roa te whakaurunga ki roto i te tinana tangata. Heoi anō, he ngoikoretanga anō hoki tō te titanium.
Ko te mātotoru o te titanium he 4.51 karamu ia henimita pūtoru, koia te tuatahi i roto i ngā rauemi konganuku māmā e toru i whakaurua mai e mātou. I taua wā anō, ko te utu tukatuka o te titanium te mea teitei rawa atu i roto i ngā mea e toru. Nō reira, he maha ngā wā ka whakamahia te titanium mō ngā tono e hiahia ana kia kaha ake, kia roa ake hoki te ora.
Ko ngā whakamahinga noa o te titanium ko:
- Hei tauira, ko ngā taputapu matū e hiahia ana kia roa te whakamahinga, me tino ātete ki te waikawa me te kawakore.
- Ngā momo taputapu hauora kua whakatōkia ki roto i te tinana tangata, ā, me whakamahi mō te wā roa, pērā i ngā prosthesis, me ētahi atu.
- E hiahia ana te umanga rererangi ki ngā wāhanga e hiahia ana ki te mama me te kaha.
- Me whai wāhanga ātete ki te waikura ngā kaipuke me ngā taputapu hōia.
#2 Konumohe – 65% te mama ake i te maitai
Ko te matotoru o te konumohe he tata ki te hautoru o te maitai (2.70g/cm3), ā, koinei te rauemi konganuku kore-ferrous e whakamahia whānuitia ana i tēnei wā. He tino ātete te konumohe ki te waikura, ā, he rite te kaha o ētahi koranu konumohe ki te maitai waro. Ahakoa he nui ake te utu o te konumohe i te maitai, he iti ake tonu te utu i te konupora me te titanium.
He tino pai te āhua o te konumohe ki te hanga me te miihini, ā, he tino pai hoki ōna āhuatanga whakarewa. I taua wā anō, he nui hoki te ngāwari o te konumohe, te kawe wera me te kawe hiko. Heoi, he iti te ātete ki te kakahu o te konumohe, ā, kāore tōna ōwehenga kaha-ki-taumaha i te rite te pai ki te titanium. Hei tāpiri, kāore te konumohe e tino pai te mahi i roto i ngā taiao pāmahana teitei pērā i ngā taiao pāmahana iti. Ko ngā ira rewa o te konumohe me te konupora he 660°C me te 650°C.
I runga i te whānuitanga o ngā whakamahinga o te konumohe, ko ōna whakamahinga matua ko:
- Ngā wāhanga hiko me ngā waea.
- He pāreti hiko whai hua mō te whakamahana me te whakamatao.
- Ngā tinana o te waka rererangi me te maha atu o ngā wāhanga rererangi.
- He hua kaihoko pakari, he iti hoki te utu pērā i ngā tāonga whare me ngā taputapu kīhini.
- Ngā wāhanga hanganga o te whare pēnei i te reera me te pakitara.
- Ngā wāhanga konumohe whakarewa me ngā wāhanga konumohe kua whakaputaia mō ngā waka.
#3 Konupora – 77% te mama ake i te maitai
Ki te whakatauritea ki te konumohe, he nui ake te utu o te konupora. Engari ki te whakatauritea ki ngā koranu titanium, he iti ake te utu o te konupora. Nō reira, he whānuitia te whakamahinga o te konupora i roto i ngā momo mara e hiahiatia ana he hanganga mama. He ngāwari te konupora ki te waikura me ngā awe matū, ā, kāore i te kaha pērā i ētahi atu konganuku e whakamahia whānuitia ana. Heoi anō, kua tino whakapai ake te hangarau koranu konupora hou me ngā tikanga maimoatanga mata i te kaha me te roa o ngā hua konupora.
He ngāwari te mīhini i ngā rauemi konupūmā, engari nā te nui o te mōrearea o te pahūtanga puehu, ka taea anake te tukatuka i roto i ngā awheawhe me ngā whare ātete puehu ngaio. He rerekē ki ētahi atu konganuku, he pai ngā kaha mimiti ru o te konupūmā, ka taea te whakaiti i te wiri o ngā taputapu tino tika. Ko te konupūmā te nuinga o te wā e whakamahia ana i ngā wāhi e hiahia ana kia tino māmā, kia iti rānei te kaha. Hei tauira, ko tōna kiato he 1.74g/cm3 noa iho.
Ko ngā tono motuhake ko:
Ngā wāhanga o ia rā pēnei i ngā peke me ngā arawhata; ngā taputapu hākinakina me ngā taputapu whakangahau mahi-teitei pēnei i ngā anga pahikara; ngā wāhanga mama i roto i ngā taputapu hōia; ngā wāhanga motuka mahi-teitei pēnei i ngā wira konupora me ngā pouaka miihini. Hei rauemi konganuku mama, he mea nui te konupora i roto i ēnei wāhanga.
Ka whakaratohia e tēnei tuhinga he matapakinga whakatairite mō te whakamahinga o ngā konganuku mama e toru e whakamahia whānuitia ana - te titanium, te konupūmā me te konumohe - hei whakaiti i te taumaha o te hua.
He tino pakari te Titanium, engari he utu nui, he uaua hoki ki te tukatuka. He mama te konupūmā, ā, ka whakaranua ki ētahi atu huānga hei whakapai ake i te kaha me te mahi. Ko te konumohe te koranu kore-ferrous tino iti te utu, he whānui hoki ngā whakamahinga.
Ko te whiriwhiri i te konganuku e whakawhirinaki ana ki te utu, te kaha me te roa o te hua. He tino pai ngā konganuku e toru ki te whakaiti i te taumaha o te hua, ā, ka pai ake te mahi me te āhua o te hua. I te mutunga o te tuhinga, kua whakahuatia mēnā me hanga e koe he hua mama, ka taea e koe te toro atu ki ngā ratonga tukatuka ngaio e whakaratohia ana e ngā toa mīhini mō te titanium, te koranu konumohe me ētahi atu rauemi.
