Me pēhea te hanga o ngā mata o te carbide?
E maiohatia ana ngā mata o te carbide mō tō rātou pakeke rawa atu, te ātete ki te pakaru, me te kaha ki te pupuri i te koi mō te wā roa, ā, he mea tino pai mō te tapahi i ngā rauemi uaua.
Ko te tikanga, ka hangaia ngā mata karāpi mā te whakamahi i tētahi tukanga e uru ana ki te whakakorikori i te paura karāpi tungsten kia totoka, ā, muri iho ka hangaia, ka whakaotia te mata. Anei tētahi tirohanga whānui mō te hanga o ngā mata karāpi:
1. Te Whakarite Rauemi Mata
- Tungsten CarbidePauraKo te rauemi matua e whakamahia ana i roto i ngā mata kāpira ko te kāpira tungsten (WC), he matū matotoru, he mārō hoki o te kāpira me te waro. Ko te paura o te kāpira tungsten ka konatunatua ki te konganuku here, ko te tikanga he cobalt (Co), hei āwhina i te tukanga whakahinuhinu.
- Te Whakaranu PauraKa whakaranua te paura tungsten carbide me te cobalt hei hanga i tētahi ranunga ōrite. Ka āta whakahaerea te ranunga kia tika ai te hanganga mō te pakeke me te pakari o te mata e hiahiatia ana.
2. Te pēhi
- Te whakahāngaiKa whakanohoia te ranunga paura ki roto i tētahi pokepokea ai, ka pēhia kia rite ki te āhua o te mata. I te nuinga o te wā ka mahia tēnei i raro i te pēhanga teitei i roto i tētahi tukanga e kīia neite pēhitanga matao isostatic (CIP) or pēhitanga uniaxial.
- Te hangaI te wā e pēhi ana, ka hangaia te āhua taratara o te mata, engari kāore anō kia tino matotoru, kia tino mārō rānei. Ka āwhina te pēhi ki te whakakīkī i te ranunga paura ki te āhua e hiahiatia ana, pērā i te āhua o te taputapu tapahi, o te mata rānei.
3. Te whakapūtanga
- Sintering Pāmahana-TeiteiI muri i te pēhitanga, ka pāngia te mata e te tukanga whakapūkara. Ko te tikanga o tēnei ko te whakamahana i te āhua kua pēhia ki roto i te oumu i ngā pāmahana e tata ana ki te1,400°C me te 1,600°C(2552°F ki te 2912°F), ka honoa ngā matūriki paura, ka hanga he rauemi totoka, kikī.
- Tangohanga HereI te wā e whakahinuhinuhia ana, ka tukatukahia hoki te here cobalt. Ka āwhina i ngā matūriki tungsten carbide kia piri tetahi ki tetahi, engari i muri i te whakahinuhinu, ka āwhina hoki ki te hoatu i tōna mārō me te pakari whakamutunga ki te mata.
- WhakamataoI muri i te whakahinuhinu, ka whakamatao mārire te mata i roto i te taiao whakahaeretia kia kore ai e ngatata, e hē rānei.
4. Te Huri me te Hanga
- Te huriI muri i te whakahinuhinu, he maha ngā wā ka taratara rawa, ka koretake rānei te mata o te karawiti, nō reira ka hurihia kia tika ngā rahinga mā te whakamahi i ngā wira whakakoi motuhake, i ngā mīhini huri rānei. He mea nui tēnei taahiraa hei hanga i te mata koi, me te whakarite kia tutuki i te mata ngā whakaritenga e hiahiatia ana.
- Te Hanga me te Whakatakoto KōtahaI runga i te whakamahinga, ka taea te hanga anō i te mata, te whakarārangi rānei. Tērā pea ko te huri i ngā koki motuhake ki te mata tapahi, te paninga, te whakatikatika rānei i te āhua whānui o te mata.
5. Ngā Maimoatanga Whakaoti
- Ngā Paninga Mata (Whiringa)Ka tāpirihia ētahi mata carbide ki ngā maimoatanga tāpiri, pērā i te paninga o ngā rauemi pēnei i te titanium nitride (TiN), hei whakapai ake i te pakeketanga, te ātete ki te kakahu, me te whakaiti i te waku.
- Te whakakanapaHei whakapai ake i te mahi, ka taea te whakakanapa i te mata kia maeneene, kia oti pai ai te tapahi, kia whakaitihia ai te waku me te whakapai ake i te pai o te tapahi.
6. Te Mana Kounga me te Whakamātautau
- Whakamātautau PakekeKo te pakeke o te mata ka whakamatautauria kia tutuki ai ngā whakaritenga e hiahiatia ana, me ngā whakamātautau noa tae atu ki te whakamātautau pakeke o Rockwell, o Vickers rānei.
- Tirotiro AhuHe mea tino nui te tika, nō reira ka tirohia ngā ine o te mata kia tino tutuki ai ngā paerewa.
- Whakamātautau MahiMō ngā whakamahinga motuhake, pērā i te tapahi, te haehae rānei, ka whakamatautauria pea te mata kia rite ai te mahi i te mea i whakaritea.
