He mea nui te mahi sintering i roto i te umanga hanga, e āhei ai te hanga i ngā wāhanga uaua me te pakari. He mea nui te mārama ki ngā kaupapa matua o te sintering mō ngā miihini, ngā kairangahau, me ngā kaiwhaiwhai. Ko te whāinga o tēnei tuhinga he ruku hohonu ki te ariā o te sintering, te tūhura i tōna tukanga, te matapaki i ōna tono, me te whakamārama i ōna painga me ōna herenga.
He aha te Sintering?
Ko te whakapūkara he tukanga e whakauru ana i te whakakīkī i ngā rauemi paura kia rite ki te papatipu totoka mā te whakamahi i te wera. Kāore te whakapūkara e tae ki te pūwāhi rewa o te rauemi, he rerekē ki ngā tukanga rewa tuku iho. Engari, ka whakamahia te horapa o ngā ngota puta noa i ngā matūriki, ka hua ake te hononga me te whakakīkī. Ka hua ake i tēnei tukanga he hanganga totoka me ngā āhuatanga miihini kua whakapaitia.
He whānui, he whaiti hoki te tikanga o te sintering. Mō te whānui, ko te sintering he tukanga e whakakotahihia ai te paura wetewete ki ngā poraka mā te kaha here totoka i tētahi pāmahana. Engari i te ao hanga rino, ko te sintering he tukanga e whakakotahi ana i te paura rino me ētahi atu rauemi kei roto te rino ki roto i te poraka horihori mahi whakarewa pai rawa atu mā te hanumi, ko tōna whakaputanga he sinter. He rerekē ngā tukanga ā-tinana me te matū e whakamahia ana e rāua. Ahakoa i whakamahia e rāua te kupu sintering.
Te Tukanga Sintering
He maha ngā wāhanga o te tukanga whakawera. I te tīmatanga, ka hangaia te rauemi mata ki tētahi āhua motuhake, ko te tikanga he paura. Kātahi ka whakakīkītia tēnei paura mā te pēhanga hei whakarite kia ōrite te āhua, kia kore ai hoki e puta he āputa. Muri iho, ka whakamahanahia te rauemi kua whakakīkītia ki roto i tētahi oumu whakawera. Ka āta whakaritea te pāmahana hei whakahaere i te hononga o ngā matūriki me te kore e rewa katoa. I te wā whakamahana, ka horapa ngā matūriki, ka hua ake te kaki me te whakakīkī. Ko te wāhanga whakamutunga ko te whakamatao i te hua kua whakawerahia, kia taea ai te totoka hei hanganga pakari, piripono hoki.
Ko te paura whakapūkara i kīia i mua ko te paura whakarewa, te paura whakakī rānei. He tukanga mahi toi tēnei mō te whiwhi i te rauemi, i te hua rānei i roto i ngā kaha me ngā āhuatanga e hiahiatia ana nā te hononga ā-tinana me te matū i waenga i ngā matūriki i te pāmahana i raro iho i te ira rewa o te wāhanga matua. He raupapa hua whakapūkara paura a HENGKO o ngā momo whakaritenga me ngā rahi tae atu kitātari kōpae, tātari kapu,tātari rama,tātari raume ērā atu anō. Ko tā mātou hua maitai kore waikura he kaha teitei, he pai te uruhanga, he tika te tātari me te ātete ki te waikura, he pai mō ngā wāhi maha. Ka whakaratohia hoki he ratonga ritenga e ai ki tāu i tono ai.
He taunekeneke ia taahiraa o te tukanga whakawera, ā, he tino hira te kukū i roto i te tukanga whakawera, nō reira he aha te tikanga o te kukū? Ko te kukū te taahiraa e mahi ana hei whakapai ake i te rauemi mata me te wahie, kia noho hei kawenga oumu e tutuki ai ngā whakaritenga o te whakapakari i te whakamahine oumu pupuhi i mua i te urunga o te rauemi mata me te wahie ki te oumu pupuhi. Ka taea te whiwhi tohu hangarau me te ōhanga teitei ake me ngā painga ōhanga i muri i te whakamahinga o te kukū i roto i te whakarewa oumu pupuhi. Ko te mea e kiia nei ko te "whakamahi pai i ngā mea katoa" me te whakamahi pai i ngā rauemi. He momo mōhiotanga hoki ki te penapena me te tiaki taiao.
