Ko te whāinga matua o te whakarewanga taiaho he whakapai ake i te whai huatanga me te kounga o ngā rauemi pakitara angiangi me ngā wāhanga tino tika. I tēnei rā, kāore tātou e kōrero mō ngā painga o te whakarewanga taiaho, engari ka arotahi tātou ki te whakamahi tika i ngā hau ārai mō te whakarewanga taiaho.
He aha i whakamahia ai te hau whakangungu rakau mō te whakarewa taiaho?
I roto i te whakarewa taiaho, ka pā te hau whakangungu rakau ki te hanganga whakarewa, te kounga whakarewa, te hohonutanga whakarewa, me te whānui whakarewa. I te nuinga o te wā, ka pā pai te pupuhi i te hau āwhina ki te whakarewa, engari ka pā kino pea.
Mā te pupuhi tika i te hau whakangungu rakau, ka āwhina i a koe:
✦Tiakina pai te puna whakarewa hei whakaiti, hei karo rānei i te waikura
✦Whakaitihia te pupuhi i puta i te tukanga whakarewa
✦Whakaitihia pai ngā pore whakarewa
✦Āwhina kia horapa ōrite te puna whakarewa i te wā e totoka ana, kia ma, kia maeneene hoki te taha o te hononga whakarewa.
✦Ka tino whakaitihia te pānga tiaki o te kohu whakarewa, te kapua plasma rānei ki te taiaho, ā, ka piki ake te tere whakamahinga whai hua o te taiaho.
I te mea ko tete momo hau whakangungu rakau, te tere rere o te hau, me te kōwhiringa aratau pupuhiKi te tika, ka taea e koe te whiwhi i te hua pai o te whakarewa. Heoi, ko te whakamahinga hē o te hau tiaki ka pā kino ki te whakarewa. Mā te whakamahi i te momo hau parepare hē ka arahi pea ki te haruru i roto i te whakarewa, ki te whakaiti rānei i ngā āhuatanga miihini o te whakarewa. Ko te tere rere o te hau he nui rawa, he iti rawa rānei, ka arahi pea ki te waikura whakarewa kino atu me te pokanoa nui o waho o te rauemi whakarewa i roto i te puna whakarewa, ka hua ake te hinga o te whakarewa, te hanganga koretake rānei.
Ngā momo hau whakangungu rakau
Ko ngā hau tiaki e whakamahia whānuitia ana mō te whakarewa taiaho ko te N2, Ar, me te He. He rerekē ō rātou āhuatanga ā-tinana, ā-matū hoki, nō reira he rerekē anō hoki ō rātou pānga ki ngā whakarewa.
Hauota (N2)
He taurite te kaha ionization o te N2, he teitei ake i te Ar, ā, he iti iho i te He. I raro i te hihi o te laser, ka noho tonu te taumata ionization o te N2 i runga i te turanga ōrite, ka taea te whakaiti i te hanganga o te kapua plasma me te whakanui ake i te tere whakamahinga whai hua o te laser. Ka taea e te hauota te tauhohe ki te koranu konumohe me te maitai waro i tētahi pāmahana hei whakaputa i ngā nitrides, ka whakapai ake i te pakarukaru o te whakarewa me te whakaiti i te pakari, ā, he nui te pānga kino ki ngā āhuatanga miihini o ngā hononga whakarewa. Nō reira, kāore i te tūtohutia kia whakamahia te hauota i te wā e whakarewa ana i te koranu konumohe me te maitai waro.
Heoi, mā te tauhohenga matū i waenga i te hauota me te kowiri tira i hangaia e te hauota ka taea te whakapai ake i te kaha o te hononga whakarewa, ka whai hua hoki ki te whakapai ake i ngā āhuatanga hangarau o te whakarewa, nō reira ka taea te whakamahi i te hauota hei hau tiaki i te whakarewatanga o te kowiri tira.
Ākoni (Ar)
He iti noa te kaha whakakoi o te Argon, ā, ka piki ake tōna taumata whakakoi i raro i te mahi a te laser. Kātahi, kāore e taea e te Argon, hei hau tiaki, te whakahaere tika i te hanganga o ngā kapua plasma, ka whakaiti i te tere whakamahinga whai hua o te whakarewa laser. Ka ara ake te pātai: he pai te argon hei whakamahi whakarewa hei hau tiaki? Ko te whakautu he Kāo. Nā te mea he hau kore mahi, he uaua te tauhohe a te Argon ki te nuinga o ngā konganuku, ā, he iti te utu o te whakamahi i te Ar. Hei tāpiri, he nui te mātotoru o te Ar, ka pai ake te totohu ki te mata o te puna whakarewa rewa, ā, ka pai ake te tiaki i te puna whakarewa, nō reira ka taea te whakamahi i te Argon hei hau tiaki tikanga.
Hīriamu (He)
He rerekē te Hīriama i te Ākona, he nui te kaha o te ionitanga ka taea te whakahaere ngāwari i te hanganga o ngā kapua plasma. I taua wā anō, kāore te Hīriama e tauhohe ki tētahi konganuku. He kōwhiringa pai rawa atu tēnei mō te whakarewa laser. Ko te raruraru anake ko te utu nui o te Hīriama. Mō ngā kaihanga e whakarato ana i ngā hua konganuku hanga-papatipu, ka nui te tāpiri a te Hīriama ki te utu whakaputa. Nō reira, ko te Hīriama te nuinga o te wā e whakamahia ana i roto i ngā rangahau pūtaiao, i ngā hua rānei he tino nui te uara tāpiri.
Me pēhea te pupuhi i te hau o te whakangungu rakau?
Tuatahi, me mārama ko te mea e kiia nei ko te "waikura" o te whakarewa he ingoa noa iho, e pā ana ki te tauhohenga matū i waenga i te whakarewa me ngā wāhanga kino o te hau, ka arahi ki te pirau o te whakarewa. I te nuinga o te wā, ka tauhohe te konganuku whakarewa ki te hāora, te hauota, me te hauwai i te hau i tētahi pāmahana.
Hei ārai i te "waikura" o te whakarewa, me whakaiti, me karo rānei i te pā atu o aua wāhanga kino ki te konganuku whakarewa i raro i te pāmahana teitei, ehara i te mea kei roto noa i te konganuku rewa engari ko te wā katoa mai i te wā e rewa ai te konganuku whakarewa tae noa ki te whakapakeketanga o te konganuku rewa, ā, ka whakamatao haere tōna pāmahana ki tētahi pāmahana kua whakaritea.
E rua ngā huarahi matua mō te pupuhi i te hau whakangungu rakau
▶Kei te pupuhi tetahi i te hau whakangungu rakau ki te tuaka taha, e whakaaturia ana i te Pikitia 1.
▶Ko tētahi atu he tikanga pupuhi coaxial, e whakaaturia ana i te Pikitia 2.
Pikitia 1.
Pikitia 2.
He whakaaro whānui tēnei mō ngā āhuatanga maha hei whiriwhiri i ngā tikanga pupuhi e rua. I te nuinga o te wā, e taunakihia ana kia whakamahia te tikanga o te hau tiaki pupuhi-taha.
Ko ētahi tauira o te whakarewa laser
1. Te whakarewanga o ngā pīni/raina tika
E ai ki te Pikitia 3, he rārangi te āhua o te whakarewa o te hua, ā, ko te āhua o te hononga he hononga pūmau, he hononga piko, he hononga kokonga kino, he hononga whakarewa taupatupatu rānei. Mō tēnei momo hua, he pai ake te whakamahi i te hau tiaki pupuhi taha-tuaka e ai ki te Pikitia 1.
2. Whakapiripiri āhua, rohe rānei
E ai ki te Pikitia 4, he tauira kati te āhua whakarewa o te hua pērā i te porowhita papatahi, te āhua papatahi maha-taha, te āhua papatahi maha-wāhanga, me ētahi atu. Ka taea te āhua hononga te hononga papatahi, te hononga piko, te whakarewa taupatupatu, me ētahi atu. He pai ake te whakamahi i te tikanga hau tiaki coaxial e ai ki te Pikitia 2 mō tēnei momo hua.
Ka pā tika te whiriwhiringa o te hau tiaki ki te kounga o te whakarewa, te whai huatanga, me te utu o te whakaputanga, engari nā te kanorau o ngā rauemi whakarewa, i roto i te tukanga whakarewa tuturu, he uaua ake te whiriwhiringa o te hau whakarewa, ā, me whai whakaaro whānui ki ngā rauemi whakarewa, te tikanga whakarewa, te tūranga whakarewa, me ngā whakaritenga o te pānga whakarewa. Mā roto i ngā whakamātautau whakarewa, ka taea e koe te whiriwhiri i te hau whakarewa e tika ana kia pai ake ai ngā hua.
Kei te hiahia ki te whakarewa laser, ā, e hiahia ana ki te ako me pēhea te whiriwhiri i te hau whakangungu rakau.
