Konganuku utu nui

konganuku utu nui - he tuatahi o te koura katoa, hiriwa, me te konukawata. e kore e ngohengohe ki te waikura, me te hāora ratou, me tenei whakatakoto ana ratou motu ke i te tahi atu konganuku. He iti o ratou Rahui, engari e pono ahurei ratou hua. Ki te kāwai ngā rangatira me te konukawata konganuku, pērā i palladium, ruthenium, iridium, rhodium me osmium. Platinum whakarewa he rerekē pūmautanga waiariki, kōngohe, te waikura resistance, reflectivity me emissivity, he hoki kawe ia waiariki, me te hiko, me ngā āhuatanga autō tiketike. e kore e ēnei ngā āhuatanga ōkiko me te matū ahurei anake konganuku ratou, engari ano hoki ratou pūhui, me ngā rauemi i runga i to ratou pūtake: alloys, kaiwhakakökï, puehu, coatings, kiriata waikura. He mahuinga ia i roto i te matū me te matūngahinu ahumahi, hikohiko, hiko, karihi, me te pere hangarau, mea ratou. whakarato ēnei konganuku te rorohiko whai tika whakahaere, me te ruri me te mana pūrere me te whakatangitangi.

konganuku rangatira katoa i nga huru maitatai faufaa e kua hiahiatia hoki te hanga o ngā rei. E āhuatanga pērā i whenu, kōngohe, plasticity, fusing kaha ki ētahi atu konganuku. i huaina utu nui Nā ki te utu nui ratou.

Ko te konganuku utu nui tino utu - koura. Ko te kotahi whakarewa anake e kua he tae kōwhai kanapa i roto i tona puka parakore. Ki te tona kaupapa, ka skyrocket tona marama. e kore he kaupapa ki te rangi hāora, ātete ki te makuku runga reira Gold. Nā ki tona tsenneyshemu rawa - resistance matū o katoa rōpū konganuku koura mohio rite te tangata pai rawa. Ko te ahumahi whakapaipai ko te pūtake o te koura parakore alloys utu nui.

He tokomaha hiahia konganuku utu nui ma, te nuinga i roto i te whakapaipai. Taua whakarewa he hiriwa. I tua atu ki te whakapaipai hiriwa whakamahia mo te hanga o te rīnena,, uku. ohaoha hiriwa Machined iho ngāwari. Tenei whakarewa he kōngohe, plasticity, te kōngohe. Kei te hoki āhuatanga i te reira e te reflectivity tiketike mo ia, kawe ia waiariki, me te hiko. He wāhanga nui o te hiriwa tangohia whakamahia i roto i te hikohiko, te whakatangitangi, mo te moni, te paninga o whakaata, i roto i te whakaahua. I roto i nga tau tata nei, kei te whakawhānui tonu te hōkai o tenei whakarewa. Na roto i te makuku kore he tino eu hiriwa. riro te reira i te atarangi mumura.

Hoki ngā konganuku pai konukawata me tona rārangi - whakarewa taimaha, me te whakangutungutu. I roto i te āhua i reira he kore konukawata i roto i tona puka parakore. Kei te aroaro o te reira i roto i te puka o te koranu tūturu ki ētahi atu konganuku utu nui pērā i palladium, ruthenium, rhodium, osmium, iridium. Platinum he pakeke runga ake i te koura me te hiriwa. Kei te iti pāngia Chemical resistance. Kei te whānui whakamahia konukawata vysokoprobny koranu i te hanga o te whakapaipai.

Ko te hanganga o te rōpū konukawata he palladium. Ko tōna āhuatanga matū o te konukawata i raro. E ia he ataahua, tata ma. Palladium Ko te tino Kōmāmā, ngāwari, me iti-rewa kirihou i te konganuku rōpū konukawata. Ka taea e ngāwari te reira whakataka, ka tae atu ki te waea. e kore e palladium whakapokea ano a maitai Nireaha ki te orooro. Kei te roto te reira i roto i te hanganga o te iti-kōeke koura ki te whakapiki ake i ona āhuatanga anti-waikura.

Ko te rōpū konukawata o konganuku ngā rhodium, rite tona konumohe ma kikorangi. āhuatanga tēnei konganuku e te pakeke, friability. He he reflectivity tiketike tūturu. whakaaro Rhodium te whakarewa matū ātete. Ko ātete ki te pānga o te hāora, māota, whanariki, he ūkuikui tenei whakarewa. Chemical me ngā āhuatanga ōkiko o te te whakamahia rhodium mō te pani oko koura, me te hiriwa.

Ruthenium - maitai tutu. brittleness pakeke a kua reira me te te rhodium. kitea tona whakamahi o tenei whakarewa i roto i te mauhaa, i roto i ngā rahinga iti e wātea ana i roto i alloys konukawata.

Ko tētahi o te whakarewa rōpū konukawata he iridium, te āhuatanga o te mea rite ki te āhuatanga o te ruthenium me rhodium. O nga konganuku katoa, ko reira tetahi o te matū, tino pūmau. Kei te kaha te whakamahia ia i roto i te ahumahi matū.

Ko te māngai whakamutunga o konganuku rōpū konukawata - osmium. e kore he kaupapa machining reira, i roto i te rewa waikawa. whakaurua nga alloys osmium te ki ake i to ratou resistance matū me te pakeke.
