Ko te whakarewa kōngohe tino - koura

Gold - Ko te whakarewa tino rongonui i roto i te hītori, i roto i te ahurea, i roto i te ōhanga. Hoki riro o ratou maringi awa o toto, whitinga tautohetohe whānau me i whawhai noa pakanga. hāngai Ko tōna faufaa mo te nunaa tangata katoa i runga i ona āhuatanga matū, me te tinana ahurei, i runga i nga peculiarities o te hanganga ā-.

Gold - Ko te whakarewa kōngohe tino. hanga rongonui reira nga wahi katoa i take whakapaipai ki Microelectronics tenei kounga.

Ko te nuinga o "konganuku" whakarewa

Ko te koura aro katoa o nga āhuatanga tino kitea e karanga pūtaiao whakarewa. Hoki kawe ia hiko, he reira te rua anake ki te hiriwa, parahi, me te palladium parakore. kawe ia Thermal - te taua hiriwa, parahi, me te konukurahina. E te kaha ki te takanga mai pūngao wera he tuarua ki te koura tāwāhi bismuth, mēkuri me te hiriwa i mua anake. Hoki atu "whakarewa" āhuatanga - kōpoke me te whakaata marama - ko reira he toa. Gold - Ko te whakarewa kōngohe te nuinga i roto i te ao, me tona kanapa - te ariā o te kōrero.

Ko te hanganga rāpoi o he hoki te koura rawa "whakarewa". Ko te mea ripekapeka āhuahanga auau ki ngā katote pai i roto i te kōpuku me te kapua mātotoru o te kukū "e" o te therebetween hau. Tenei wahi ngota kėia irahiko noa, tikanga i runga i te taumata pūngao waho. hanga ratou he ope ātaahua i waenganui i nga ngā kōpuku wini e whakarato ana i te kaha ki te deform te whakarewa te ore e haapeapea i te tapatahi whānui. Ko te ara tino maitai kōngohe.

Faaotiraa o te plasticity

Mai i te Πλαστική Kariki ( "sculpting", "niao") mai te kupu "kirihou", i hoatu pakiaka ki ētahi atu e pā ana ki te huringa i roto i te puka o te totoka. Plasticity - taonga State Mārō ki te huri i te āhua me te rahi, me te pupuri deformation wäriu i muri i te mutunga o ope waho, kahore te huri i te rōrahi me te Break.

No te konganuku, he reira tetahi o nga āhuatanga tino nui e taea ki te whakamahi ia ratou i roto i te mahi. Te kore te kaha ki te tāpiri i te workpieces i hanga o whakarewa te āhua e hiahiatia e waiho e taea hoki ara te māmā o ngā tūemi rā. Gold - te whakarewa kōngohe tino, me tuhinga ona - ko te tauira o te aha āhua taea hanga e koe ture nui rauemi ki rikarika ki, pēhanga awhiowhio, makoha, tuhi, me ētahi atu Reverse te tikanga o taonga o te rauemi he pakarukaru ...

whakamātautau te kōngohe

Āhuatanga o te ukanga whakarewa te tikanga tautuhia i raro i ngā whakamātautau pateko. Ko te tino tino ko te whakamātautau kurut. Hei kitea i roto i nei ko te whakarewa kōngohe, me i raro ki te pānga taua tauira rahi rite i raro i ngā āhuatanga pāmahana rite. rahinga deformation i te mea e taea ki te tu atu tauira maitai i mua i whaturama, - he mehua whāinga o te kōngohe.

faaiteraa tau o te hua kurut whakamātautau e rua tauwehe nui. Elongation - te ōrau o te nui haere roa o te tauira i muri i te āputa i meinga e te deformation ki te taketake. Ko te whakarewa kōngohe tino - koura - he te auau - 65%. No te whakarite: te rino - 40-50 o konumohe - 30-40.

Ko te tohu tuarua o te plasticity - whāiti whanaunga o te tauira ripeka-motu. Gold kua Ko 90% neke atu i te mea kua ia i te aroaro o te matao te wāhanga tuatahi o te tauira. I roto i te konumohe, tenei ahua - 80% o te parahi - 75%.

Soft, kōngohe, me te roa

E ai ki te tauine Mohs o pakeke i te tere koura - 2.5-3.7. I roto i tona puka parakore tenei whakarewa ko tino ngawari maha rauemi noa, me te Rakuraku ki te maripi maikuku ranei. Na reira, ki te karo i tuhinga kākahu koura tere, mo ratou whakarewa ahumahi tāpiri motu āhuatanga motuhake whakaū, te nuinga hiriwa parahi ranei. He whai koura, me poke kino. Ko te whakarewa kōngohe te nuinga i roto i te taka pūmotu i te aroaro o te mata, konukawata, cadmium whanariki ranei riro he pakarukaru.

Ko te mārū o te āhua motuhake o te koura, e kīnaki reira e tona taikaha me te kōngohe. Whakangāwari o niao me tukatuka kōrero kīnaki taumata tiketike o te kaha kurut - 3300 kg / cm ^2. Kei te whakamahia i tēnei huinga ahurei o ngā āhuatanga ōkiko me te pūkaha o te koura mo te wa roa. Tauira - rau koura.

Croutes domes i Russia koura parakore ...

Ahakoa te hītori roa o te koura, i no tonu tenei whakarewa ki te onge, me te utu nui. Ko te reira i te whakarewa kōngohe tino. hanga ana tēnei kounga te whakamahi o te konumohe koura mo huānga roto whakapaipai, ranei ara ki te taupoki ana i te domes hahi utu whai hua. Tino iti konganuku utu nui e hiahiatia ana mō te pani i te wāhi nui o te 1 karamu o te pereti e taea e te wāhi uninhibited pepa o 1 m ^2.

Ahakoa tikanga ā-o te whakaputa rau mō te whakakikorua koura hanga reira taea ki te whakatutuki i te matotoru o tetahi mano o te mirimita. Tenei matotoru taea te platelets koura ki te piri i runga i te mata e tika ana ki te attraction rāpoi. Ko te hangarau mō te whakaputa te kohiko tino pai ake. Na hoki flattening whārangi koura whakamahia raina robotic, engari i roto i te tukanga - kōngohe tiketike tīmata rauemi.

miro koura

Ko te kaha o te koura ki te te tu te ope kurut waho whawhati te mōhiotia i te timatanga rawa o tona whakamahi arumoni. Te hanga i tētahi waea mo te whakapaipai i whakapumautia i roto i nga wa onamata - mohio nga rangatira onamata aha whakarewa ko te kirihou tino. I roto i te waenganui o te hua microwire XX rautau ki te matua koura, ko 7 nga wa te kikokore atu i te huruhuru tangata e ara ki te mātao kirihou. Mai i te 1 karamu o te whakarewa koura i unu kakawaea tonu e pā ana ki 3,5 km te roa.

hangarau o teie mahana mai te koura matotoru waea o runga ki te maha microns, tonu te atu whanaketanga o painga hangarau whakarewa.
