Metals whakangutungutu. mōhiohio Basic e pā ana ki Tungsten.

konganuku whakangutungutu - he tirohanga whānui

Ko te tikanga, ka korero o "konganuku whakangutungutu" kia matau e he konganuku e whai he pāmahana rewa tiketike rawa enei, kia tae ai 4000 ° C. Molybdenum, tantalum, Tungsten, Niobium me rhenium - taketake konganuku whakangutungutu. taea hoki te tāpiri tenei rārangi, me etahi - chromium, vanadium, osmium, hafnium, me konganuku zirconium, tae te pāmahana rewa 2123 ° C.

He pārekareka hoki o ratou āhuatanga konganuku whakangutungutu. Ko te kupu, hei tauira, ngā tohu o te molybdenum me Tungsten pakeke taea te whakamahi o enei konganuku mo te maimoatanga wera o ngā rauemi i raro i te korehau. E hua i hanga o te tahi mau konganuku whakangutungutu āhuatanga ahurei, hei tauira, kakawaea Tungsten tonu kakawaea pāmahana ki 3073 ° C.

Ko te ātete o konganuku whakangutungutu taea te pēnei ki o ratou kino matua. Whakapā ki te hāora tino pānga i runga i nga āhuatanga waiariki o konganuku whakangutungutu. Ko te take te whakamahi o te konganuku i roto i tenei rōpū tenei - i roto i te taiao e taea ai e te tino taratahi ratou i te rangi.

Tungsten - te pūtake o konganuku whakangutungutu i metallurgy

Tungsten Ko tetahi o te konganuku tino whakangutungutu. Ko te ira whakakoero o te mea teitei ake i te toenga, Tungsten Tungsten - maitai taimaha, he reira taea ki te utu aho pai, reira te hoki tino weldable. Tungsten Ko te whakarewa onge, tona ihirangi i roto i te kirinuku tae 0,0055 anake%, kihai i kitea ai i roto i te tūāwhiorangi solar, a ehara i te mea i roto i te vairaa pape. Otiia e kore e he iho ki te whakarewa konganuku iti onge tona rongonui.

Ko te whakamahi o te Tungsten

Tungsten konganuku whakamahia mō te hokohoko ngangana kakawaea, e kua whakamahia i roto i te whakaaro rama rite te huānga whakawera - i roto i oumu korehau resistance. Ko te tiketike te mātotoru o Tungsten taea te whakamahi o tenei whakarewa rite te counterweight mō projectiles rerekē. Ka rite ki te kawehiko Tungsten whakamahia i roto i TIG fehokotaki'anga. I roto i nga alloys mārō o te Tungsten carbide e whakamahia rite filler.

Tungsten rite molybdenum, ka whakamahia tantalum te rite te tikanga i roto i nga alloys, e kua whakamahia i roto i ngā wāhanga o te wāhi hangarau karihi. Ko te kaha ki te tu atu ki te pāmahana tiketike rawa - te whakaaro matua mo e i hanga enei alloys.
