1. Whakamahia te tikanga whakamātautau pakeke Vickers o ngā wāhanga kua whakarewaina (whakamātautau pakeke Weld Vickers):
I te mea ka rerekē te hanganga iti o te wāhanga hononga o te whakarewa (te hononga whakarewa) i te wā whakarewa i te wā o te tukanga hanganga, ka taea te hanga hononga ngoikore i roto i te hanganga whakarewa. Ka taea e te pakeke o te whakarewa te whakaata tika mēnā he tika te tukanga whakarewa. Kātahi ka whakamahia te tikanga tirotiro pakeke Vickers hei āwhina i te aromatawai i te kounga o ngā whakarewa. Ka taea e te kaiwhakamātautau pakeke Vickers o te Wheketere Whakamātautau Pakari o Laizhou Laihua te mahi whakamātautau pakeke i ngā wāhanga whakarewa, i ngā wāhi whakarewa rānei. I te whakamahi i te kaiwhakamātautau pakeke Vickers hei whakamātautau i ngā wāhanga whakarewa, me mōhio ki ngā āhuatanga whakamātautau e whai ake nei:
Te papatahi o te tauira: I mua i te whakamātautau, ka hurihia e mātou te whakarewa hei whakamātautau kia maeneene tōna mata, kia kore he paparanga waikura, he kapiti me ētahi atu hapa.
I te rārangi pokapū o te whakarewa, tangohia he pūwāhi i te mata piko i ia 100 mm hei whakamātautau.
Ka rerekē ngā hua ina whiriwhiria ngā kaha whakamātautau rerekē, nō reira me whiriwhiri e tātou te kaha whakamātautau e tika ana i mua i te whakamātautau.
2. Me pēhea te whakamahi i te taputapu whakamātautau pakeke Vickers (micro Vickers hardness tester) hei kimi i te hohonutanga o te paparanga kua whakapakeketia?
Me pēhea te kite i te hohonutanga o te paparanga maitai kua whakapakeketia mā te maimoatanga mata pērā i te whakakāpūhau, te whakanitiritiri, te tango kāpūhau, te whakakāpūhau, me ētahi atu, me ngā wāhanga maitai kua whakamārōhia ki te induction?
Ko te hohonutanga o te paparanga whakapakeke whai hua ka whakamahia whānuitia hei whakamahana i te mata kia puta ai ngā huringa hanganga me te mahi i runga i te mata o te maitai kia tutuki ai te pānga o te whakanui ake i te pakeketanga me te kaha me te pakari. E pā ana ki te ine mai i te ahunga poutū o te mata o te wāhanga ki te rohe hanganga moroiti kua tohua. Ko te tawhiti paparanga whakapakeke rānei o te pakeketanga moroiti kua tohua. I te nuinga o te wā ka whakamahia e mātou te tikanga pakeketanga piki o te whakamātautau pakeketanga Vickers hei kite i te hohonutanga o te paparanga whakapakeke whai hua o te mahi. Ko te kaupapa matua ko te kite i te hohonutanga o te paparanga whakapakeke whai hua i runga i te huringa o te pakeketanga moroiti-Vickers mai i te mata ki waenganui o te wāhanga.
Mō ngā tikanga whakahaere motuhake, tirohia te ataata whakahaere mō te whakamātautau pakeke Vickers a tā mātou kamupene. Anei tētahi whakataki whakahaere māmā:
Whakaritea te tauira kia rite ki te hiahia, ā, me whakakanapa te mata whakamātautau kia rite ki te mata whakaata.
Tīpakohia te kaha whakamātautau o te taputapu whakamātautau pakeke Vickers. Ka inehia te pikinga pakeke i ngā wāhi e rua, neke atu rānei. Ka inehia te pakeke Vickers i runga i tētahi, neke atu rānei, rārangi whakarara e poutū ana ki te mata.
Mā te tuhi i tētahi kōpiko mārō i runga i ngā raraunga inehia, ka taea te mōhio ko te tawhiti poutū mai i te mata o te wāhanga ki te 550HV (i te nuinga o te wā) ko te hohonutanga o te paparanga whakapakeke whai hua.
3. Me pēhea te whakamahi i te taputapu whakamātautau pakeke Vickers mō te whakamātautau pakari whati (tikanga whakamātautau pakeke Vickers)?
Ko te pakari o te pakaru ko te uara ātete e whakaatuhia ana e te rauemi ina pakaru te tauira, te wāhanga rānei i raro i ngā āhuatanga kore pumau pērā i te ngatata, i ngā hapa rite ki te ngatata rānei.
Ko te pakari o te whati e tohu ana i te kaha o tētahi rauemi ki te aukati i te horapa o te pakaru, ā, he tohu tauanga hoki mō te pakari o tētahi rauemi.
I te wā e mahi ana i te whakamātautau pakari whati, tuatahi whakakanapahia te mata o te tauira whakamātautau ki te mata whakaata. I runga i te taputapu whakamātautau pakeke Vickers, whakamahia te kōhao taimana kōniko o te taputapu whakamātautau pakeke Vickers hei hanga kōhao ki runga i te mata kua whakakanapahia me te kawenga o te 10Kg. Ka puta ngā kapiti kua oti te hanga i mua i ngā pito e whā o te tohu. I te nuinga o te wā ka whakamahia e mātou he taputapu whakamātautau pakeke Vickers hei tiki raraunga pakari whati.
