Tikanga tukatuka mata o ngā tokotoko taiaho karaihe hapaira kua pania ki te titanium

Ko ngā tioata kōhatu titanium Ti:Al2O3 (te kukū tāpiri 0.35 wt% Ti2O3), ko ngā papa tioata e rite ana ki te tūtohi rere tukanga o te tikanga tukatuka mata o te tokotoko taiaho tioata kōhatu titanium o tēnei mea hou e whakaaturia ana i te Pikitia 1. Ko ngā mahi whakarite motuhake o te tikanga tukatuka mata o te tokotoko taiaho tioata kōhatu titanium o tēnei mea hou koia ēnei:

<1> Te tapahi aronga: ka whakatakotoria tuatahitia te karaihe kōhatu taimana, kātahi ka tapahia kia rite ki te pou tapatoru te āhua, mā te waiho i te tahua tukatuka o te 0.4 ki te 0.6 mm e ai ki te rahi o te tokotoko taiaho kua oti.

<2>Te huri porotaka me te huri pai o te pou: Ka hurihia te pou kore ki te porowhita tapawhā, porotaka rānei me ngā mea whakakoi 120~180# silicon carbide, boron carbide rānei i runga i te mīhini huri porotaka, me te hapa taper me te hapa waho-porowhita o ±0.01mm.

<3> Tukatuka mata pito: tukatukahia ngā mata pito e rua mā te pae taiaho kōhatu titanium me te mata pito huri kāpirati boron W40, W20, W10 ki runga i te kōpae maitai. I roto i te tukanga huri, me aro nui ki te ine i te poutū o te mata pito.

<4> Te whakakanapa matū-mīhini: ko te whakakanapa matū-mīhini te tukanga whakakanapa i ngā tioata ki runga i te papa whakakanapa me ngā pata o te otinga whakairo matū kua oti te whakarite. Ka whakakanapahia te mahi whakakanapa me te papa whakakanapa mō te nekehanga me te waku whanaunga, i te mea kei roto i te paru rangahau he matū whakakanapa (e kiia ana ko te wai whakakanapa) hei whakaoti i te whakakanapa me te awhina o.

<5> Te whakairo waikawa: I muri i te whakakanapatanga, e ai ki te whakaahuatanga i runga ake nei, ka whakanohoia ngā tokotoko kōhatu titanium ki roto i te ranunga o te H2SO4:H3PO4 = 3:1 (v/v), i te pāmahana 100-400°C, ā, ka whakairohia ki te waikawa mō te 5-30 meneti. Ko te kaupapa he tango i te tukanga whakakanapatanga i runga i te mata o te pae taiaho i puta mai i te kino ā-pūkaha o raro i te mata, me te tango i ngā momo paru, kia whiwhi ai i te taumata ngota o te maeneene me te papatahi, te hanganga whatunga o te mata ma.

<6> TE MAIMOATANGA WERA O TE PAPA: Hei whakakore atu i ngā ahotea me ngā karawarawa o te papa i puta mai i te tukanga o mua, kia puta ai he mata papatahi i te taumata ngota, i muri i te keri waikawa, i horoia te tokotoko kohatu taimana ki te wai tango-iona mō te 5 meneti, ā, i whakanohoia te tokotoko kohatu taimana ki te taiao 1360±20° C. i te pāmahana pumau o te 1 ki te 3 hāora i roto i te hau hauwai, ā, i tukuna ki te maimoatanga wera o te mata.
