I roto i te umanga mahi rakau,maripi tungsten carbideHe mea tino nui ngā mea e whakamahia ana i runga i ngā taputapu, he pakari, he koi, he roa te ora, he aha te mea e pai ake ai te maripi? Ko ngā rauemi te take nui, i konei, ka kitea pai e tātou mai i ngā rauemi mata taketake o tengā mata o te tungsten caribide, kia mōhio ai koe ki te take.
Ko ngā rauemi matua o ngā taputapu mahi rakau kāpia he wāhanga mārō (ngā kāpia pakeke-teitei) me te wāhanga honohono (te mea here whakarewa), ā, he tāpiringa hei whakapai ake i te mahi. Ko ngā whakarōpūtanga me ngā mahi motuhake koia ēnei:
I. Ngā Rauemi Mata Matua
1. Wāhanga Mārō (85%–97%)
Pūmua Tungsten Carbide (WC):
- Mahi Matua: E whakarato ana i te pakeketanga tino teitei (HRA 89–94) me te ātete ki te kakahu. E 70%–97% te roa o te wāhanga pakeke.
- Pānga Rahi o te Witi:
Wiri Matariki (3–5μm): Tino pakari (Kaha Pakaru Whakawhiti ≥2.2 GPa), he pai mō te miihini pānga (hei tauira, te tapahi i ngā rakau mārō).
Wiri Maeneene (0.5–1μm): Kua piki ake te pakeke (HRA 93.5), ātete ki te kakahu ↑30% (e pai ana mō ngā taputapu whakaoti).
Kāpira Titanium (TiC) / Kāpira Tantalum (TaC):
- Mahi: Ka whakarei ake a TiC i te pakeketanga whero (ātete ki te 1000°C); Ka whakapai ake a TaC i te hanganga o te kōpura, ā, ka ātete hoki ki te pakaru wera (hei tauira, mō te tukatuka i ngā rakau mārō kua whakakikoruatia).
- Te nui o te tāpiri: 5%–10% (TiC), 3%–5% (TaC). Ka whakaitihia te pakari e te nui rawa.
2. Wāhanga Hononga (3%–15%)
Koparata (Ko):
- Mahi Matua: Whakarei ake i te pakari. Mā te nui ake o te ihirangi Co ka whakapai ake i te ātete pānga (Ka eke te Kaha Pakaru Whakawhiti ki te 2.2 GPa i te 15% Co).
- Herenga: Ka whakaitihia te ātete kakahu e te ihirangi >12% (ka heke te pakeke ki te ~HRA 89).
Nikara (Ni):
- Mahi: Whakakapi i te Co hei whakaiti i te utu, ā, he pai ake te ātete ki te waikura (he pai mō te rakau he nui ake te makuku i te 15%).
- Mahi: Ko te pakari he tata ki te 80% o ngā mea ōrite e hangai ana ki te Co, ko te pakeke HRA 89.5 (he kōwhiringa taputapu ōhanga).
II. Te Hononga i waenganui i te Hanganga Rauemi me te Mahi a te Utauta
Ko te mahi (mārō, pakari, ātete ki te kakahu) o ngā taputapu mahi rakau carbide ka whakatauhia tika e te ōwehenga WC/Co, ngā momo tāpiri, me te rahi o te kōpura. Kei raro nei ngā whanaungatanga matua o te hanganga-mahi me ngā raraunga whakamātautau tautoko:
| Kaupapa Whakatakotoranga | Te pakeketanga (HRA) | Te Kaha o te Pakaru Whakarara (MPa) | Taupū Ātete Kakahu (Tauira=100) | Horopaki e tika ana |
| WC 94% + Co 6% | 92.5 | 1,500 | 100 | Whakaoti (MDF/Papa Matūriki) |
| WC 88% + Co 12% | 89 | 2,200 | 75 | Te Whakatārewatanga (Rākau Mārō/Rākau Pōkaikaha) |
| WC 85% + Co 10% + TaC 5% | 91.2 | 1,800 | 110 | Te Tapahi Tere-Tiketike (Rākau Whakakirikiri) |
| WC 90% + Ni 10% | 89.5 | 1,700 | 80 | Rakau he nui ake te makuku i te 15% (ātete ki te waikura) |
E ai ki ngā tuhinga o mua, ko te pikinga o te utu o ngā rauemi mata mō ngā taputapu carbide i te tau 2025 i puta mai i te huinga o te kore taurite i waenga i te tuku me te tono, te rautaki rauemi, te whakataetae o te ao, me te whakapai ake i ngā ahumahi. Kāore pea he hekenga utu nui i roto i te wā poto. Whakapā maiChengdu Huaxin Carbide mō ngā uiui utu me ngā otinga taputapu carbide mō ngā momo ahumahi.
