Ringa uku Alumina ritenga Ringa karetao uku

Ko te ringa uku i hangaia e tā mātou kamupene he mea hanga ki ngā rauemi mata uku parakore teitei, i hangaia mā te pēhi matao isostatic, te sintering pāmahana teitei me te miihini tika. Ka taea e te tika o ngā āhuatanga te eke ki te ±0.001mm, ka taea e te whakaotinga te eke ki te Ra0.1, ā, ka taea e te pāmahana whakamahinga te eke ki te 1600℃. E whakamahi ana tā mātou kamupene i te hangarau hononga uku ahurei, ko te pāmahana whakamahinga o te ringa uku tuwhera i muri i te hononga ka eke ki te 800℃.

He rauemi uku motuhake te uku Alumina, i roto i te whakarōpūtanga uku he uku motuhake, no ngā uku waikura, ko tōna pakeke Rockwell ko HRA80-90, ko te pakeke tuarua anake ki te taimana, he nui ake te ātete kakahu i te maitai ātete kakahu me te maitai kore waikura, ko tōna kiato he 3.5g/cm3, he mama ake i te maitai, he mama, he ātete kakahu, he ātete pāmahana teitei, he maha ngā āhuatanga pai e kohikohi tahi ana, he rongonui ngā uku Alumina, ā, ko rātou te rauemi uku e whakamahia whānuitia ana i roto i ngā uku waikura.

Mā te tukanga whakawera pāmahana teitei, ka hangaia e te alumina he hanganga tioata piripono, ōrite. Mā tēnei hanganga ka nui te mārō, ka teitei te ira rewa, ā, ka tino pumau te matū. Me pai te mātotoru o ngā hua e whakamahia ana i roto i te ao hikohiko, kia pai ai te ātete ki te takai me te pakaru.

I roto i te mara o te hanga moroiti me te nano, ka pā tika te matotoru o te hua ki tōna ātete piko me te ātete kakahu. Mō te ringa karetao, ko tōna hanganga kōpiko matotoru ka homai he kaha piko pai me te pakeke teitei. Mā tēnei hanganga moroiti ka taea e te ringa miihini te pupuri i ngā āhuatanga miihini pumau i roto i ngā momo taiao mahi uaua, kia pai ai te kaha ki te kawe kawenga me te whakaroa i tōna roanga mahi. Hei tāpiri, ko ngā hua he hanganga kōpiko matotoru, pērā i ngā ringa miihini, he mea nui hoki i roto i ō rātou ātete kakahu, ka taea te whakaiti i te tupono ki te whakaputa matūriki i te wā e whakamahia ana, me te pupuri i te ma o te taiao whakaputa.
