Kusiyana pakati pa tungsten alloy ndi simenti carbide

Ngakhale onse tungsten aloyi ndisimenti carbidendi mtundu wa aloyi mankhwala a kusintha zitsulo tungsten, onse angagwiritsidwe ntchito muzamlengalenga ndi ndege navigation ndi madera ena, koma chifukwa cha kusiyana kwa zinthu anawonjezera, zikuchokera chiŵerengero ndi kupanga ndondomeko, ntchito ndi ntchito ya onse a iwo ali ndi lalikulu. kusiyana.

I. Tanthauzo

Tungsten alloy, yomwe imadziwikanso kuti high specific gravity alloy, ndi aloyi yokhala ndi tungsten ufa monga chopangira chachikulu ndi faifi tambala, chitsulo, mkuwa ndi zinthu zina ngati zida zothandizira.Zomwe zili mu tungsten nthawi zambiri zimakhala pakati pa 85% ndi 99%.

Carbide ya simenti, yomwe imadziwikanso kuti tungsten chitsulo, ndiye kuti, ndi aloyi yokhala ndi zitsulo zotayirira monga tungsten carbide monga chopangira chachikulu ndi cobalt, faifi tambala, molybdenum ndi zinthu zina monga binder.Zomwe zimapangidwira nthawi zambiri zimakhala pakati pa 10% ndi 20%.
Chachiwiri, machitidwe

Aloyi yapamwamba kwambiri yokoka imakhala ndi malo osungunuka kwambiri, kachulukidwe, mphamvu ndi kuuma, pulasitiki yabwino, kukana kutentha, kukana kwa dzimbiri, kukana kwamphamvu, kukana kwa okosijeni ndi chitetezo.

Chitsulo cha Tungsten chilinso ndi zinthu zofanana ndi ma aloyi a tungsten, ngakhale kuuma kwake kwamafuta ndi ubwino wake wokana kuvala ndizodziwikiratu, makamaka chifukwa chakuti zimakhalabe zosasinthika pa 500 ° C ndipo zimakhalabe zolimba kwambiri pa 1000 ° C.Komabe, brittleness yake ndi yokwera kwambiri, choncho imapanga kudula.

Chachitatu, njira yopanga

Kukonzekera masitepe a tungsten aloyi: 1) Kukonzekera zakuthupi: tungsten mankhwala monga ammonium tungstate, zipangizo wothandiza monga faifi tambala, chitsulo, mkuwa ndi zinthu zina kapena mankhwala;2) kupanga ufa: pali kupopera kuyanika njira ndi makina alloying njira;3) kupanga: mutatha kusakaniza tungsten ufa ndi kupanga wothandizira, extrusion imalowetsedwa mu makina opangira, ndiye kuti ziwalo zooneka bwino zimatha kukonzekera;4) sintering: pambuyo sintering mankhwala, bungwe la aloyi ndi yunifolomu ndi ntchito mabuku apamwamba ntchito wonse.

Masitepe pokonzekera simenti carbide: 1) Chotsani pamwamba zosafunika zatungsten carbideparticles ndi cobalt mbewu;2) Gwirani zinthu zomwe zili pamwambazi ndikuzisakaniza mu chosakaniza, kenaka perani kuti mupeze ufa wa alloy;3) Extrude aloyi ufa mu extrusion kufa kupeza simenti carbide precursors, ndiye kusakaniza ndi madzi ndi kuwonjezera zomangira kupanga zitsulo ufa slurry;4) Pangani slurry kukhala ufa ndi kupopera granulator, ndiye sinter ndi kutentha mankhwala.ndiye sintered ndi kutentha mankhwala.
