Rangahau me te Whakamahinga o ngā Hua Oneone Zirconia Auaha
Mō ngā rauemi ahumahi, he maha ngā tāngata noa e kite ana he hoha te kaupapa, engari he maha ngā āhuatanga uaua o roto.zirconia, hei tauira. I ngā wā o mua, i whakaarohia pea e te tangata he mea whakamahi noa iho mō ngā mea pēnei i ngā maripi uku me ngā niho rūpahu, he mea mārō, he kanapa. Engari mō te hunga o tātou e whai wāhi ana ki te rangahau me te whakawhanake rauemi me ngā tono ahumahi, he taonga nui tēnei. Ko ngā hua onepu zirconia auaha kua puta ake i ngā tau tata nei, inā koa, kua tino whakaoti rapanga nui, ā, he tino whai hua hoki.
E maumahara ana ahau ki taku haerenga ki tētahi whakaaturanga ahumahi i ngā tau e rua kua pahure ake nei, me taku kōrero ki tētahi miihini tawhito kua mahi i ngā rauemi ātete ahi mō ngā tekau tau. I papaki ia i tōna huha, ā, ka mea, "E hoa, kāore koe i te mārama! He nui rawa ngā tono a te umanga whakarewa mō ngā rauemi! Kei te piki haere te pāmahana, ā, kei te kino haere te taiao. Kāore e taea e ngā rauemi tuku iho te tu atu. Hei tauira, tirohia te zirconia. E mōhio ana te katoa he pai - he ātete ki te pāmahana teitei, ā, he pumau te matū. Engari ko te onepu zirconia i hangaia mā te whakamahi i ngā tukanga tuku iho he koretake te parakore, he koretake te ōrite o ngā matūriki, he kore pumau rānei. He tino utu nui hoki, he uaua ki te whakamahi. He maha ngā wā, e rite ana ki te 'kei reira te hiahia, kāore te kaha.'"
I tino tika tana mahi. Koinei tonu te whāinga taketake o tā mātou rangahau me te whakawhanaketanga o te onepu zirconia auaha—kāore ianei i te mea hei wikitoria i ēnei wero tawhito?
Nō reira, kei hea tonu te whakaaro mō te auahatanga? Tukua ahau kia whakamārama.
Tuatahi, me huri te "uho". He raruraru tā te zirconia o mua: he koretake tōna hanganga tioata. I te wā e rerekē ana te pāmahana, ka taea e ia te "whawhai" i roto, ka puta he kapiti moroiti. I roto i te wā, ka heke te mahi. Ko tā mātou huarahi hou he whakahou nui i te hanganga me te tukatuka. Mā te whakauru i ngā whakaū matatau ake, pērā i te yttrium, me te whakakotahitanga o te sintering pāmahana tino teitei me ngā tikanga kuru me te whakarōpū matatau ake, kua tutuki i a mātou tēnei hua whakamiharo: "zirconia kua whakaūhia te wāhanga." Ki tētahi atu kīanga, he rite ki te hanga i tētahi "anga maitai" i roto i ngā matūriki zirconia, me te whakarite kia pakeke ina hiahiatia, kia ngāwari hoki ina hiahiatia, he rerekē ki te rauemi pakarukaru, ngāwari te pakaru o mua. Hei tāpiri, kei te piki haere tonu te parakore, me te pupuri i ngā taumata poke ki te taumata tino iti.
Tuarua, me aro nui hoki ki te āhua me te āhua. Ko ngā onepū zirconia auaha e aro nui ana ki te āhua - ehara i te mea mō ngā whakataetae ataahua anake, engari mō te āhua o te matūriki me te tohatoha rahi. Ko ngā matūriki "mātotoru" i mua he koki, he rahi kore taurite, he kino mō ngā tono tino tika. Ināianei, mā roto i ngā tukanga matatini pēnei i te mira hau me te whakarōpūtanga porotītaha, ka taea e tātou te whakaputa paura zirconia porowhita tata me te rahi matūriki tino ōrite. Hopukia he ringa, ā, ka rite ki te paraoa pai rawa atu, engari he tino teitei tōna pakeke. He nui ngā painga o tēnei ōritetanga: ahakoa he paninga, he mea whakakoi rānei, he pumau, he ōrite hoki ngā hua, me te kore he tono kore taurite.
Kāore he hua o te kōrero nui; me whakamahi pai te whanaketanga. Ko ēnei mahi auahaonepu zirconiae tino hiahiatia ana ināianei i roto i ngā momo mara mahi papai.
Ko te mea tuatahi, he mea nui te whakarewa tika, inā koa mō ngā wāhanga angiangi, matatini hoki o te konukōre, pērā i ngā mata o te mīhini rererangi me ngā mata o te tāhū hau. Ka eke te pāmahana whakarewa ki runga ake i te 1,000 nekehanga Celsius, ka nui rawa ngā tono mō te anga pokepoke. Ko ngā paninga o runga i hangaia ki tēnei onepu zirconia hou ka whakarato i te pumau pai me te tauwehenga whānui wera e rite ana. Ka tino whakapai ake tēnei i te mutunga o te mata o ngā whakarewa, ka kore e kitea ngā hapa pērā i te kohi onepu me ngā kōhao, ka tino whakaiti i te utu o te whakaotinga i muri mai. E ai ki ngā tohunga toi mohio, "Mā te whakamahi i tēnei onepu hou, he tino whakamiharo te mahi!"
Ko tētahi atu tono he mea tino kounga teiteite huri me te whakakanapa. Me tino maeneene ngā mata o ā mātou karāhe waea pūkoro, arotahi kāmera, me ngā momo angiangi haurua-ira; ahakoa te rakuraku iti rawa ka hua ake he para. He wai whakakanapa tino whai hua te paura moroiti zirconium oxide hou, me tōna pakeke teitei, tōna rahi matūriki ōrite, me ōna āhuatanga matū me te miihini pai rawa atu. Ka tino whakahaerehia te tere tango, ā, he iti te ātete ki te rakuraku, ka tutuki he mata tino maeneene i te taumata nano, tae noa ki te taumata atomika. Ki te kī ngāwari, he tino maeneene te mata o tō waea nā reira.
Kei reira anō hoki ngā paninga ārai wera. Me pēhea e taea ai e ngā miihini rererangi me ngā tāpoi hau te tu atu i ēnei pāmahana uaua? Ka rehuhia ngā wāhanga matua ki te "koti whakamahana wera." Ko tētahi o ngā rauemi matua e whakamahia ana i roto i tēnei koti ko ngā uku i hangaia ki te waikura zirconium. Ko te onepu waikura zirconium auaha, me tōna ātete pāmahana teitei me te pumau āhuahanga, koia te rauemi mata matua mō te whakarite i ēnei paura paninga taumata teitei, e pā tika ana ki te pai o te miihini me te roa o te ora.
Hei tāpiritanga, ka kitea i roto i ngā uku hanganga mō ngā taiao uaua, ngā mea whakakā pakari matatau, tae atu ki ngā rauemi koiora hauora. Kei te whānui haere ōna whakamahinga.
I te heke mai, ki taku whakaaro ka whānui ake te ara mō te onepu zirconia auaha. Nā te tere o te whanaketanga o ngā ahumahi pēnei i te photovoltaics, ngā maramara semiconductor, me te rererangi, ka piki haere te tono mō ngā whakaritenga mahi mō ngā rauemi. Kāore e kore ka whakawhanakehia ngā hua onepu zirconia me ngā āhuatanga parakore, pai ake, ōrite ake, me te mahi ka taea te whakahaere. Tērā pea i tētahi rā, ka tiaho i ngā wāhi kāore e taea e tātou te whakaaro i tēnei wā.
Nō reira, kaua e whakaititia te hiranga o ēnei kirikiri iti nei. He nui te mātauranga kei roto, ā, ka taea e rātou te whakakaha i ngā ahumahi nui. Ko te uara o te auahatanga kei roto i te whakaputa i te pūmanawa katoa o tētahi rauemi hei whakatutuki i ngā tono nui o tō tātou wā.
