Bambanci tsakanin tungsten gami da siminti carbide

Ko da yake duka tungsten gami dasiminti carbidewani nau'i ne na samfurin gami na ƙarfe tungsten miƙa mulki, duka biyu za a iya amfani da su a cikin sararin samaniya da kewayawa jirgin sama da sauran filayen, amma saboda bambance-bambancen abubuwan da aka ƙara, rabon abun da ke ciki da tsarin samarwa, wasan kwaikwayon da amfani da su kuma suna da manyan. bambanci.

Tungsten gami, wanda kuma aka sani da high takamaiman na'ura gami, shi ne gami da tungsten foda a matsayin babban albarkatun kasa da nickel, baƙin ƙarfe, jan karfe da sauran abubuwa a matsayin karin kayan.Abubuwan da ke cikin tungsten gabaɗaya suna tsakanin 85% zuwa 99%.

Siminti carbide, wanda kuma aka sani da tungsten karfe, wato, alloy tare da refractory karfe carbide kamar tungsten carbide a matsayin babban sinadari da cobalt, nickel, molybdenum da sauran abubuwa a matsayin mai ɗaure.Abun ɗaure gabaɗaya tsakanin 10% zuwa 20%.
Na biyu, wasan kwaikwayon

High musamman nauyi gami yana da babban narkewa batu, yawa, ƙarfi da taurin, mafi kyau plasticity, zafi juriya, lalata juriya,, tasiri juriya, hadawan abu da iskar shaka juriya da kuma garkuwa sakamako.

Tungsten karfe kuma yana da irin wannan kaddarorin ga tungsten gami, kodayake taurin zafinsa da fa'idodin juriya sun fito fili sosai, galibi a cikin gaskiyar cewa ya kasance baya canzawa a 500 ° C kuma har yanzu yana da ƙarfi a 1000 ° C.Duk da haka, karyewar sa yana da yawa sosai, don haka yana aiwatar da aikin yankewa.

Na uku, tsarin samarwa

Matakan shiri na tungsten alloy: 1) shirye-shiryen kayan aiki: tungsten mahadi irin su ammonium tungstate, kayan taimako irin su nickel, iron, jan karfe da sauran abubuwa ko mahadi;2) foda yin: akwai SPRAY bushewa hanya da inji gami alloying hanya;3) forming: bayan hadawa tungsten foda tare da kafa wakili, extrusion ne allura a cikin kafa na'ura, sa'an nan za a iya shirya sassa-dimbin yawa sassa;4) sintering: bayan sintering jiyya, kungiyar na gami ne mafi uniform da m yi mafi girma overall yi.

Matakai don shirye-shiryen siminti carbide: 1) Cire ƙazanta na samantungsten carbidebarbashi da hatsin cobalt;2) A daka wadannan kayan da ke sama a hada su a cikin mahautsini, sai a nika su a samu foda;3) Extrude da gami foda a cikin extrusion mutu don samun cimined carbide precursors, sa'an nan kuma Mix su da ruwa da kuma ƙara daure yin karfe foda slurry;4) Yi slurry ɗin ya zama foda ta hanyar fesa granulator, sa'an nan kuma siter da zafi magani.sa'an nan a tsoma baki da zafi.
