I roto i ngā tukanga whakaputa o te keri maina, te matū, te hiko me ētahi atu ahumahi, he taputapu matua ngā awhiowhio mō te wehewehe i ngā ranunga totoka-wai. Heoi, mā te tukatuka roa o ngā rauemi he pakeke rawa, he tere rere nui hoki ka ngāwari te pakaru me te haehae o roto, e kore e whakapoto noa i te roa o te ora o ngā taputapu engari ka pā pea ki te tika o te wehenga me te whakapiki i ngā utu tiaki mō ngā umanga. Ko te putanga mai o ngā raina awhiowhio uku silicon carbide e whakarato ana i tētahi otinga kounga teitei mō tēnei raruraru ahumahi.
Ina tae mai kingā uku karāhe silicon, he tokomaha pea kāore i te mōhio ki tēnei mea, engari he tino hototahi ōna āhuatanga ki ngā "hiahia" o ngā awhiowhio. Tuatahi, he tino kaha te ātete ki te kakahu – ki te whakatauritea ki ngā arai rapa me te whakarewa tuku iho, he tino pakari ngā uku silicon carbide, tuarua ki te taimana anake. Ahakoa te pakaru roa mai i ngā matūriki one me te paru, ka taea e rātou te ātete ki te kakahu me te whakaroa i te huringa whakakapinga o te arai. Mō ngā umanga, ko te tikanga o tēnei ko te whakaiti i te wā kore mahi mō te tiaki me te whakapūmau i ngā tukanga whakaputa.
Tuarua, he tino ātete ki te waikura. Ina whakamahia ngā paru kei roto ngā wāhanga waikawa me te kawakore, ka ngāwari te waikura me te waikura o ngā arai whakarewa, ā, ka taea hoki te waikura me te tawhito o ngā arai rapa e ngā matū. Heoi, he pumau ngā āhuatanga matū o ngā uku silicon carbide, ā, ka taea te tu atu ki te mimiti o ngā momo rauemi waikawa me te kawakore, ka karo i te parahanga rauemi, i te pakaru rānei o ngā taputapu i puta mai i te kino o ngā arai. He tino pai mō ngā ahumahi he āhuatanga mahi waikura pērā i ngā ahumahi matū me te whakarewa.
Hei tāpiritanga, he pai ngā painga o ngā uku karawiti silicon, arā, he maeneene te mata, he iti hoki te ātete. Ko te whai huatanga o te mahi a te awhiowhio e whakawhirinaki ana ki te rere maeneene o te paru i roto. Ka taea e te arai maeneene o roto te whakaiti i te ātete o te rere o te paru, te whakaiti i te whakapaunga pūngao, me te whakarite i te tika o te wehenga rauemi, kia pumau ake ai te kounga o te hua. Ko ngā āhuatanga o te "ātete iti + tino tika" ka waiho te arai uku karawiti silicon hei "tohu tāpiri" mō te whakapai ake i te mahi a ngā awhiowhio.
Tērā pea ka pātai tetahi, me ēnei rauemi pakari, he uaua te tāutanga me te whakamahi? Kāore i te pērā. Ko te arai uku silicon carbide he hoahoa āhua-rua, ka taea te whakarerekē ngāwari kia rite ki ngā whakaritenga o te awhiowhio. He māmā, he whai hua hoki te tukanga tāutanga, ā, e kore e nui rawa te whakararuraru i te tukanga whakaputa taketake. Ā, kua manatokohia hoki tōna ātete pānga e ngā āhuatanga mahi tūturu. I raro i te mahi noa, ehara i te mea ngāwari te raru pēnei i te pakaru me te wetewete, ā, he tino pono tōna pono.
I ēnei rā, me te pikinga ake o te hiahia mō te whai huatanga, te utu, me te tiaki taiao i roto i te hanga ahumahi, kua waiho te whiriwhiri i ngā taputapu taputapu pakari me te whai hua hei huarahi nui mō ngā umanga ki te whakaiti i ngā utu me te whakanui ake i te whai huatanga. Ko te arai porowhita uku silicon carbide, me ōna painga matua o te ātete ki te kakahu, te ātete ki te waikura, me te iti o te whakapaunga pūngao, kei te noho hei "arai pai" mō te maha atu o ngā umanga ahumahi, e whakarato ana i te tiaki mō te mahi pumau o ngā taputapu me te whakapai ake i te whai huatanga o te whakaputa.
