Induku yethusi ye-Tungsten
iyisakhiwo esinezigaba ezimbili i-pseudo-alloy ikakhulukazi esakhiwe izakhi ze-tungsten nezethusi.Kuyinto ehlanganisiwe yensimbi ye-matrix.Ngemuva kokuthi izinto ezihlanganisiwe zixutshwe, akukho ukusabela kwamakhemikhali okwenzekayo, futhi ngayinye igcina izakhiwo zokuqala zomzimba nezomshini.Lokhu kwaziswa kulungiselelwe indlela ethile yenqubo ye-powder metallurgy.I-Tungsten yakha uhlaka lwamathambo ku-alloy, futhi ithusi lingena esikhaleni se-tungsten skeleton, ehlanganisa izinzuzo zokuncibilika okuphezulu nokumelana nokushisa okuphezulu kwe-tungsten ngokwayo.Ukuzwela kwe-notch kuthuthukisa ipulasitiki ye-alloy.
Yiqiniso, lapho ucubungula induku yethusi ye-tungsten, izinyathelo zokuphepha ezihambisanayo zidinga ukwaziwa.Lapho kwenziwa ama-alloys e-tungsten-copper ukwenza amakhona acijile nezindonga ezincanyana, amaphutha angase avele ngenxa yomthelela noma amandla okulayisha ama-machining ngokweqile.Uma imikhiqizo ye-tungsten-copper-silver-tungsten alloy ibhojwa emigodini, sicela unake ukuphakela lapho izimbobo ezidlulayo sezizobhobolwa.Layisha amandla, gwema ukungasebenzi kahle kwemishini, ingxubevange ye-tungsten yethusi ayinawo uzibuthe, sicela uqinisekise ukuthi umkhiqizo ulungiswe ngokuqinile ngaphambi kokusebenza.
Ngaphezu kwalokho, isivinini sokukhipha kanye nokusika izintambo zomshini wokukhipha ugesi kanye nezinduku zethusi zokusika izintambo ze-tungsten zihamba kancane, okuyinto evamile.Kuma-alloys akhiwe nge-tungsten nethusi, okuqukethwe kwethusi kwama-alloys avamile ku-10% -50%, futhi ama-alloys enziwa ngendlela ye-powder metallurgy.Ine-conductivity kagesi enhle, i-thermal conductivity, amandla amahle okushisa aphezulu kanye ne-plasticity ethile.Emazingeni okushisa aphakeme kakhulu, njengangaphezu kuka-3000 degrees Celsius, ithusi ku-alloy liyancibilika futhi liyahwamuka, limunce inani elikhulu lokushisa futhi linciphise izinga lokushisa lendawo yezinto.Ngakho-ke, lolu hlobo lwempahla lubizwa nangokuthi impahla yokujuluka yensimbi.
