Rehu Plasma Āhuarangi – Ngā Otinga Kākahu Ahumahi
Whakaahuatanga Hua
Te Whakaputa Plasma: I roto i te pū rehu, ka puta he pewa hiko i waenganui i te cathode me te pūwero mā te whakakā auau-teitei, mā te pewa whakapā rānei, ka whakakāhia ngā hau mahi pēnei i te argon me te hauota hei hanga i tētahi rerenga plasma tere-teitei, pāmahana-teitei.
Te Whakamahana me te Whakateretere i ngā Rauemi: Ka whāngaihia te rauemi paninga (te nuinga he paura) ki te rohe matua o te jet plasma mā te whāngai paura, ka whakamahanahia ki te āhua rewa, ki te āhua rewa-haurua rānei i roto i te wā poto rawa, ā, ka whakatereterehia e te jet tere-teitei.
Te Whakatakotoranga Kiriata: Ka pāngia te mata o te mea mahi kua tukatukahia i ngā tere tino tiketike e ngā matūriki rewa, ka huri te āhua kirihou me te whakamatao tere, ka whakarārangihia paparanga i te paparanga hei hanga i tētahi paninga mahi matotoru.
Ngā Whakatakotoranga Hua
| Momo | Te Rehu Plasma |
| Te pāmahana pewa plasma | 10,000–20,000℃, he pūtake wera pāmahana tino teitei ka taea te whakarewa i ngā rauemi ira rewa tino teitei pērā i te zirconium oxide me te tungsten, e whakarato ana i te tino whakapumautanga mō te rehu uku. |
| Te tere o te mura | 1,000–3,000 m/s, ka tukuna e te jet tere-teitei te pūngao nekeneke teitei ki ngā matūriki, ka whakapai ake i te kiato paninga me te kaha piri, he pai mō ngā āhuatanga mahi uaua. |
| Mana rehu | 20–80 kW, te kaha o te pūtake wera ka taea te whakarerekē; he pai te mana teitei mō ngā paninga matotoru/ngā rauemi ira rewa teitei, he pai te mana iti mō ngā paninga angiangi tino tika. |
| Hau mahi | Hau hau matua (ka whakau i te parāma) + hau hau āwhina hauwai/hauota (ka whakanui i te pāmahana mura, ka whakarei ake i te kaha rewa o ngā rauemi). |
| Te tere whāngai paura | 10–100 karamu/min, e whakatau tika ana i te pai o te whakatakoto; mā te tere taurite ka whakarite kia rawaka te rewa o ngā rauemi me te paninga ōrite. |
| Te tawhiti rehu | 80–150 mm, hei whakataurite i te mōrearea o te wera nui o te rauemi mahi me te pānga o te piri o ngā matūriki, kia mau ai te kounga o te paninga. |
| Te matotoru o te paninga | 0.05–5 mm, he ngāwari, he whakarerekētanga hoki. Ka whakamahia ngā paninga angiangi hei ātete i te kakahu/whakamarumaru, ko ngā paninga matotoru ia ka whakamahia hei whakatika i ngā wāhanga/tiaki i te waikura. |
| Pūngao | 1–5%, he iti iho i te rehu noa. Ka ārai pai te paninga matotoru i ngā mea waikura, he pai mō ngā whakaritenga hiri me te tiaki waikura. |
| Te kaha o te here | 30–80 MPa. He tino piri, ka taea te tu atu i ngā kawenga taumaha me ngā pānga, he pai mō ngā tono kawenga teitei pēnei i te mīhini hinu me ngā wāhanga rererangi. |
| Te pakeke o te paninga | HV1000–1800 (ka rerekē i runga i te rauemi). He tino pakari ngā paninga uku/cermet, ā, he tino ātete ki te kakahu. |
Ngā Āhuatanga o te Hua
● E 3–5 ngā wā e nui ake ai te pāmahana o te pewa plasma i tō ngā mura noa, ā, ka taea e ia te rewa i ngā rauemi hangarau katoa, tae atu ki ngā konganuku, ngā koranu, ngā uku (Al₂O₃, ZrO₂), me ngā mea hanga uku.
● Ka hinga i tēnei ngā herenga o ngā tikanga rehu tuku iho ki ngā ira rewa o ngā rauemi, kia taea ai te whakarite i ngā paninga mahi tino pai.
2. Te Mahi Paninga Tino Pai:
● Teitei te mātotoru: He iti te pūngao o te 1–5%, e ārai ana i te waikura, e whakapai ake ana i te ātete ki te waikura me te roa o te ātete ki te kakahu.
● Te kaha o te here: Ka hangaia e te pānga matūriki tere-teitei he hononga honohono ā-mīhini me te hononga whakarewa, ka taea te tu atu i ngā pānga ahotea i raro i ngā āhuatanga mahi uaua.
● Ngā mahi kanorau: Mā te whiriwhiri i ngā rauemi rerekē, ka taea te whakatutuki i ngā mahi maha pēnei i te ātete ki te kakahu, te ātete ki te waikura, te ātete ki te pāmahana tiketike, te whakamarumaru, te whakamarumaru wera, me te hototahi ki te koiora.
3. Te Whakahaere Tika i te Tukanga:
● He maha ngā tawhā ka taea te whakahaere tika, pērā i te mana, te ōwehenga hau, te tere whāngai paura, me te tawhiti rehu, kia taea ai te hoahoa tika i te matotoru o te paninga, te hanganga, me te hanganga moroiti.
● Tautoko ana i ngā mahi aunoa me ngā mahi karetao, kia mau ai te kounga o te paninga i te wā e hangaia ana te papatipu.
