Ngā whatu rupi, te tokotoko rupi, te matapihi whatu, te taimana, te karaihe taiaho

Ngā whatu rupi, te tokotoko rupi, te matapihi whatu, te taimana, te kohatu taiaho, te karaihe, te ahua matua.

Whakaahuatanga Poto:

Ko te rupi (alpha-Al ₂O₃:Cr³ +) he tioata hangai i hangaia ki te hapaira (Al₂O + ₃) i konatunatua ki ngā katote chromium (Cr³ + +), he tino pai ngā āhuatanga whatu, he pakeke teitei, he pumau matū hoki. Ko ngā taputapu whatu rupi ko te tokotoko rupi (tokotoko rēseri), te pōro rupi (wira whāngai/arataki), te matapihi whatu rupi (matapihi pēhanga), e whakamahia whānuitia ana i roto i te pūnaha rēseri, ngā mīhini tika, ngā whakamātautau ahumahi me ētahi atu mara.

Ngā Āhuatanga

Ngā āhuatanga o te whatu rupi:

1. Mahi whatu:
Te whānuitanga o te tuku mārama: 400nm~700nm (e kitea ana e te tata ki te infrared), ko te tihi mimiti āhuatanga Cr³ + kei te 694nm (mārama whero).

He teitei te taupū whakaata (~1.76), ka taea te whakakikorua i te mata ki te kiriata ārai-whakaata (AR) hei whakapai ake i te tuku mārama (> 99%@694nm).

2. Ngā āhuatanga ā-ringa:
Ko te pakeke Mohs he 9 (tuarua ki te taimana), he ātete pai ki te kakahu, he pai mō ngā taiao waku taumaha.

He kaha pēhi teitei (>2GPa), he ātete ki te pānga, kāore e ngawari ki te pakaru.

3. Te pumau o te wera:
Ko te ira rewa he 2050℃, he pai ake te kawe wera (35W/m·K) i te karāhe, ātete ki te waikura pāmahana teitei.

4. Te koretake o te matū:
Ātete ki te waikawa me te kawakore (haunga te waikawa hauwaiwai), ātete ki te waikura, he pai mō ngā taiao ahumahi kino.

Te tono mō ngā whatu Ruby:

(1) Rōpī rākau (rōpī rēseri)
Taiaho pātere: Hei reo whakanui tuatahi hei whakatutuki i te putanga taiaho, e whakamahia ana mō te taiaho whero 694nm (pēnei i te ataahua hauora, ngā taputapu rangahau pūtaiao).

Taiaho whakawhiti Q: Whakamahia ana i roto i ngā mahi ahumahi pēnei i te tohu taiaho me te awhe.

(2) Pōro rupi (wira whāriki/arataki)
Mīhini tino tika: Whakamahia mō ngā peera tino tika, ngā taputapu karaka, ngā wira arataki muka, te tauwehenga waku iti (<0.01), te roa o te ora.

Ngā taputapu hauora: ngā taputapu pokanga, ngā peera hononga, te ātete ki te waikura paturopi.

(3) Matapihi whatu rūpi
Matapihi pēhanga teitei/mahana teitei: e whakamahia ana mō te pūoko pēhanga, te matapihi tirotiro rūma mura (pēhanga >100MPa).

Whakamātautau ahumahi: hei atamira karuārai, matapihi ine-ārai, ātete ki te rakuraku, ātete ki te parahanga.

Ngā whakaritenga hangarau：

He tūranga nui ngā karu whatu rupi, he pakari, he pai te tuku mārama, ā, he ātete nui ki te taiao, ā, he mea nui tēnei i roto i te hangarau taiaho, te mīhini tika me te tirotiro ahumahi. Ka āwhina a XKH i ngā kiritaki ki te arotau i te mahi a te taputapu me te whakaiti i ngā utu mā roto i ngā ratonga ritenga motuhake.

Ratonga ritenga a XKH：

Ka tukuna e XKH te whakaritenga katoa o ngā karu whatu rupi: Mai i te tipu tioata (te kukū tāpiri Cr³ + + + ka taea te whakarite 0.05%~0.5%), te miihini tika (te ātete ā-ahu pae/pōro/matapihi ±0.01mm), te paninga karu (kiriata ārai-whakaata/kiriata whakaata teitei @ te roangaru motuhake), ki te whakamātautau mahi (te tuku mārama, te pakeke, te tiwhikete ātete pēhanga), te tautoko mō ngā tauira whanaketanga puranga iti (te ota iti rawa o te 10 ngā wahi) ki te whakaputa papatipu ahumahi, te tautoko muri-hoko hei whakatutuki i ngā hiahia nui o te taiaho, te miihini, te tirotiro me ētahi atu mara.
