He nui ake te "pai ki te mata" o ngā pirepire karāhe ki te whakataurite ki ētahi atu mea whakakoi, pērā i te alumina, te silicon carbide, me te kirikiri maitai. Ko te take matua o tēnei āhuatanga ko ōna āhuatanga ā-tinana me ā-matū motuhake. Ko te pai ki te mata o ngā pirepire karāhe ka kitea i roto i te kaha ki te horoi, ki te whakakanapa rānei i ngā mata me te whakaiti i te kino ki te wāhanga mahi tonu.
Anei ētahi āhuatanga matua e whai wāhi ana ki tēnei āhuatanga:
1. Āhua me te Hanganga: Porowhita vs. Koki
- Ngā Pīra Karāhe Porowhita: He porowhita te āhua o ngā pīra karāhe. I te wā e pupuhi ana i te onepu ki runga i ngā mata o te mea mahi, ka whakatūria he hononga pūwāhi. Ka hua ake i tēnei aratau pa he iti te kukū o te ahotea. He rite tonu te mahi ki te pānga "tā" "hurihuri" rānei, ko te nuinga o te mahi he tango i ngā poke mata pakarukaru, pērā i ngā paparanga waikura me ngā kiriata peita tawhito, me te kore e uru hohonu ki roto i te rauemi o te mea mahi.
- Ngā Mea Whakakoi Koki: He rerekē, ko ngā mea whakakoi pērā i te kōrunuma parauri, te kirikiri maitai, me te para parahi he koi, he koretake hoki ngā taha. Ina whakamahia mō te pupuhi onepu, ka honoa ngā rārangi, ka puta he ahotea ā-rohe nui. He rite tēnei ki ngā whao iti maha e whakairo ana i te mata.
Mā te āhua porowhita o ngā pirepire karāhe ka ārai i te tapahi me te pakaru i puta mai i ngā taha koi, ā, ka whakaitihia te kakahu o ngā mea mahi me te pikinga o te taratara o te mata.
2. Te pakeke o ngā rauemi: Te āhua ōrite me te taea te whakarerekē
Ko te pakeke o ngā pirepire karāhe kei waenganui i te 6 ki te 7 i runga i te tauine Mohs. He nui tēnei taumata pakeke hei tango i ngā poke mata noa, pērā i te waikura (me te pakeke Mohs o te 4 – 5) me ngā kiriata peita tawhito. I te wā kotahi, he iti iho, he rite rānei ki te pakeke o te maha o ngā rauemi whakarewa.
3. Pānga Whakakaha o te Peening
Ko te pānga porowhita o ngā pirepire karāhe ki ngā mata whakarewa ka puta he paparanga ahotea pēhi ōrite, iti hoki. He maha ngā painga o tēnei paparanga:
- Te Ātete Ngenge Whakarei Ake: Ka whakapai ake i te kaha ngenge o ngā wāhanga whakarewa, ka ātete pai ki te tīmatanga me te horapa o ngā kapiti.
- Te Whakaiti i te Mōrearea o te Waikura Āhuatanga: Ka whakaitihia e te paparanga ahotea pēhanga te tūponotanga o te waikura ā-taumahatanga.
- Te Ātete Paku Pai Ake: Mā te whakapakeke i te mata o te rauemi i te makariri, ka nui ake te ātete pakū.
4. Whakaotinga Mata
Nā te āhua porowhita me ōna āhuatanga pānga, ka puta he mata ōrite, he maeneene, ā, kāore he karawarawa koi mai i ngā pirepire karāhe, e kiia ana ko te "otinga satin". Ka whakaratohia e tēnei otinga he papa pai mō ngā tukanga rehu, paninga, whakapuru hiko rānei i muri mai, kia kaha ai te piri o te paninga.
I tetahi atu taha, ka hangaia e ngā mea whakakoi koki he āhua taratara o te mata me ngā tihi me ngā awaawa. Ahakoa ka taea hoki e tēnei te whakapai ake i te piri ki tētahi taumata, ka nui ake te rauemi paninga e pau ana, ā, ka hua ake he āhua mata kāore i te tino ataahua.
I runga i ēnei painga, he maha ngā whakamahinga o ngā pirepire karāhe i roto i ngā mahi e tino hira ana te kounga o te papa, pērā i te tukatuka i ngā wāhanga tino tika, ngā pokepokea ai, ngā wāhanga rererangi, ngā hua kowiri tira, me ngā whakarewa konumohe. He kōwhiringa pai rawa atu ēnei hei whakatutuki i te taurite i waenga i te horoinga mata whai hua me te tiaki i te papa.
