I roto i ngā ahumahi pēnei i te microelectronics, te optoelectronics me te biopharmaceuticals,whakamahana kanapa(BA), te whakapūkara, te whakakorekore rānei (AP),te whakakanapa hiko (EP)me te maimoatanga tuarua korehau e whakamahia whānuitia ana mō ngā pūnaha paipa parakore-teitei, ma hoki e tuku ana i ngā pāpāho tairongo, waikura rānei. Ngā hua rewa (VIM+VAR).
A. Ko te Hiko-Whakakanapa (Hiko-Whakakanapa) e kiia ana ko te EP. Mā te whakakanapa hiko-matū, ka taea te whakapai ake i te āhua me te hanganga o te mata, ā, ka taea te whakaiti i te horahanga o te mata ki tētahi taumata. He kiriata chromium oxide matotoru te mata, he tata te kaha ki te taumata noa o te koranu, ā, ka whakaitihia te nui o te pāpāho - he pai te nuinga mō te karaehe hiko.ngā hau parakore teitei.
B. Ko te Whakamahana Kanapa (Bright Annealing) e kiia ana ko te BA. Ko te maimoatanga wera pāmahana teitei i roto i te āhua hauwai, i te āhua korehau rānei, i tetahi taha, ka whakakore i te ahotea o roto, ā, i tetahi atu taha, ka hanga he kiriata whakakorekore i runga i te mata o te paipa hei whakapai ake i te hanganga āhua me te whakaiti i te taumata pūngao, engari kāore e whakanui ake i te taratara o te mata - he mea pai mō te GN2, CDA, me ngā hau kore-tukatuka.
C. Ko te mea i whakapūkaratia me te mea i whakawāteatia/i whakakanapatia mā te matū (Pickled & Passivated/Chemically Polished) e kiia ana ko AP me CP. E kore te whakapūkaratia, te whakawāteatia rānei o te paipa e whakanui ake i te taratara o te mata, engari ka taea te tango i ngā matūriki e toe ana i runga i te mata, me te whakaiti i te taumata pūngao, engari e kore e whakaiti i te maha o ngā paparanga - e whakamahia ana i roto i ngā paipa o te taumata ahumahi.
D. Ko te ngongo horoi whakarewa tuarua korehau Vim (Vacuum Induction Melting) + Var (Vacuum ArcRemelting), e kiia nei ko V+V, he hua nā te Kamupene Metala o Sumitomo. Kua tukatukahia anō i raro i ngā āhuatanga pewa i roto i te āhua korehau, e whakapai ake ana i te ātete ki te waikura me te taratara o te mata. Te Tohu – he mea e tika ana mō ngā hau hiko tino waikura, pērā i: BCL3, WF6, CL2, HBr, me ētahi atu.
