1. He aha te Waea Kovar?
1.1 Whakamāramatanga Matua
He waea rino-nikara-kopara te waea Kovar, he mea rewa ki te korehau, i hangaia hei whakahaere tika i te whānui o te wera.
Ko tōna painga nui ko te ōrite ki te tauwehenga whānui wera o te karāhe borosilicate me ngā uku, e taea ai te hiri ā-haumaru maeneene.
1.2 Te Hanganga Matū Paerewa
He tino whakahaeretia te hanganga o te waea Kovar hei whakarite i te mahi pumau:
- Rino (Fe): 53-54% (taurite)
- Nikara (Ni): 28.5-29.5%
- Koparata (Ko): 16.8-17.8%
Ko te nui o ngā huānga iti (Mn, Si, C) e kore e neke atu i te 0.5% te mōrahi mō ia huānga.
1.3 Ngā Paerewa Matua me ngā Whakatakotoranga
E tutuki ana i ngā paerewa o te ao kia rite ai ngā tono katoa.
- ASTM F15 (paerewa matua mō ngā hua koranu Kovar)
- UNS K94610, Werkstoff Nr. 1.3981 (whakaingoa rawa o te ao)
E mōhiotia ana hoki ko 4J29 i roto i ngā paerewa Hainamana, ka taea te whakawhiti me te Nilo-K i ētahi rohe.
2. Ngā Āhuatanga Matua o te Waea Kovar
2.1 Te Whanuitanga Wera Iti me te Pūmau
Ko tōna tauwehenga whānui wera (4.6-5.2×10⁻⁶/℃, 20-400℃) he tino ōrite ki te karāhe borosilicate.
Mā tēnei ka whakakorea ngā kapiti ahotea i te wā whakamahana me te whakamatao, kia pono ai te hiri.
2.2 Te Āheitanga Tukatuka Pai Rawa
He pai tōna ngāwari, ā, ka taea te kume hei waea angiangi, ka taea te piko, ka taea hoki te whakarewa.
He pai mō te tuhi matao, te tā, me ngā momo tikanga whakarewa (te pewa hauhā, te whakarewa taiaho).
2.3 Teitei o te Pāmahana me te Pūmautanga Hermetic
Ka mau tonu te pumau o tana mahi i ngā pāmahana tae atu ki te 450℃, me te ira rewa o te 1450℃.
Ka hanga hiri ā-hau ki te karāhe/uku, he mea nui mō ngā mahi korehau me te pono nui.
3. Waea Kovar me ngā Waea Koranu Rite: Ripanga Whakataurite
E whakaatu ana te ripanga i raro nei i ngā painga ahurei o te waea Kovar ki ngā waea nikara constantan me te nikara cupro:
| Tawhā Mahi | Waea Kovar | Waea Constantan | Waea Nikara Kuporo 80/20 |
| Tauwehenga Whānui Wera (20-300 ℃) | 4.6-5.2×10⁻⁶/℃ | ±20 ppm/℃ | ±100 ppm/℃ |
| Te Pūwāhi Rewa | 1450℃ | 450℃ | 1300℃ |
| Painga Matua | Hiri karāhe/uku, iti te whakawhanuitanga | Ātete pumau | Te ātete ki te waikura o te moana |
| Te Whakamahinga Noa | Tākai hiko, ngongo korehau | Ngā ātete tika, ngā ine taumahatanga | Waea moana, whakawhiti wera |
4. Me pēhea te whakamahi i te waea Kovar? Ngā horopaki matua mō te whakamahi
4.1 Te Tākai Hiko me te Ārahi-Haumaru
Whakamahia hei waea mata mō ngā ngongo korehau, ngā transistors, ngā diodes, me ngā ara iahiko whakauru.
Ka taea te hiri ā-haumākū mā te whakamahi i ngā ārai karāhe, hei tiaki i ngā wāhanga o roto mai i te makuku me te poke.
4.2 Te Rererangi me te Rererangi
