He aha te mea e whakamātao ana:
Ko te whakamahana, e kiia ana ko te whakapakeke, ko te whakamahana me te whakamatao i muri mai o te maitai i te tere e piki ake ai te pakeke, i runga i te mata, i te taha katoa rānei. Mō te whakapakeke korehau, ka mahia tēnei tukanga i roto i ngā oumu korehau e taea ai te eke ki te pāmahana tae atu ki te 1,300°C. Ka rerekē ngā tikanga whakamahana e pā ana ki te rauemi e tukatukahia ana engari ko te whakamahana hau mā te whakamahi i te hauota te mea tino noa.
I te nuinga o te wā, ka puta te whakapakeketanga i te taha o te whakamahana anō i muri mai, arā, te whakamātao. I runga i te rauemi, ka whakapai ake te whakapakeketanga i te pakeketanga me te ātete ki te kakahu, ka whakahaere rānei i te ōwehenga o te pakari ki te pakeketanga.
He aha te whakamahana:
Ko te whakamahana he tukanga whakamahana e whakamahia ana ki ngā konganuku pēnei i te maitai, i ngā koranu rino rānei hei whakatutuki i te pakari ake mā te whakaiti i te pakeketanga, e haere tahi ana me te pikinga o te ngāwari. Ko te whakamahana ka mahia i muri i te tukanga whakapakeketanga mā te whakamahana i te konganuku ki te pāmahana i raro iho i tētahi pūwāhi tino nui mō tētahi wā, kātahi ka tukua kia whakamatao. He tino pakeke te maitai kāore i whakamahanatia engari he maha ngā wā he pakarukaru rawa mō te nuinga o ngā mahi. Ko te maitai waro me ngā maitai taputapu mahi matao ka whakamahanahia i ngā pāmahana iti ake, ko te maitai tere teitei me ngā maitai taputapu mahi wera ka whakamahanahia i ngā pāmahana teitei ake.
He aha te Whakamahana:
Te whakamahana i roto i te korehau
Ko te maimoatanga wera i roto i te whakawerawera he tukanga e whakamahanatia ai ngā wāhanga, kātahi ka whakamatao mārire kia ngawari ake te hanganga o te wāhanga, kia pai ake ai hoki te hanganga o te rauemi mō ngā mahi hanga e whai ake nei.
Ina whakamahanahia i raro i te korehau, ka whakaratohia ngā painga e whai ake nei ki te whakataurite ki te whakamahana i raro i te āhuarangi:
Te karo i te waikura intergranular (IGO) me te waikura mata. Te karo i ngā wāhi tango-waro. Te horoi i ngā mata pātea, ngā mata o ngā wāhanga i muri i te maimoatanga wera, kāore e hiahiatia te horoi i ngā wāhanga.
Ko ngā tukanga whakamahana tino rongonui ko:
Ka mahia te whakamahana whakamāmā ahotea i ngā pāmahana tata ki te 650°C, ko te whāinga kia whakaitihia te ahotea o roto o ngā wāhanga. Ko ēnei ahotea toenga ka puta mai i ngā mahi tukatuka o mua pērā i te whakarewa me ngā mahi miihini matomato.
Ka taea e ngā ahotea toenga te arahi ki te whakapōturitanga kāore e hiahiatia i te wā o te tukanga maimoatanga wera, inā koa mō ngā wāhanga angiangi. Nō reira, e taunakihia ana kia whakakorea ēnei ahotea i mua i te mahi maimoatanga wera "tūturu" mā te maimoatanga whakamāmā ahotea.
E hiahiatia ana te whakamahana anō-kirita i muri i ngā mahi hanga matao hei whakahoki mai i te hanganga moroiti taketake.
He aha te otinga me te koroheketanga
Ko te pakeketanga he tukanga e whakamahia ana hei whakanui ake i te kaha mā te whakaputa i ngā matūriki o te rauemi whakarewa i roto i te hanganga whakarewa. Ko te maimoatanga otinga ko te whakamahana i te whakarewa ki te pāmahana e tika ana, me te pupuri i taua pāmahana kia roa kia uru ai tētahi, ētahi rānei o ngā wāhanga ki roto i te otinga totoka, kātahi ka whakamatao tere kia mau ai ēnei wāhanga ki roto i te otinga. Mā ngā maimoatanga wera matūriki i muri mai ka taea te tukunga whakahaere o ēnei wāhanga mā te taiao (i te pāmahana rūma) mā te hanga rānei (i ngā pāmahana teitei ake).
Ngā oumu e tūtohutia ana mō te maimoatanga wera
