High speed steel is an alloy steel with a complex composition containing carbide forming elements such as tungsten, molybdenum, chromium, vanadium and cobalt. Palo eohle ea lintho tse alling e fihla ho ba 10 ho isa ho 25%. E ka lula e le thata haholo tlasa mocheso o phahameng (hoo e ka bang 500 ℃) ka lebelo le phahameng, hrc e ka ba kaholimo ho 60. Ena ke tšobotsi ea bohlokoa ka ho fetisisa ea HSS - holo e khubelu. Le steel sesebelisoa ka ho emisa le ho futhumatsa mocheso le mocheso o tlase, leha mocheso o tla theoha haholo, empa ha mocheso o le ka tekanyo e ts'oanang le Naha e kopaneng, e ile ea lahleheloa ke bokhoni ba ho kuta tšepe, e lekanyang tšepe ea koloi ea khabone ea khabone. Le tšepe e lebelo haholo ka lebaka la bofubelu bo khubelu, ho etsa liphoso tsa lithulusi tsa khabone tsa khabone.
Tšepe e lebelo haholo e ne e sebelisoa haholo ho hlahisa lisebelisoa tse rarahaneng le tšusumetso le ho senyeha, ho etsa litopo, mochini o ile a hlokahala a hlokahala.
Tloo 'me u ithute ka likhoele tsa tungsten
Tungssen steel (carbide) e na le letoto la thepa e ntle joalo ka mathata a maholo a phahameng le ho hanyetsa khatello ea maikutlo, joalo ka ha ho sa fetohe ho sa fetohe le mocheso oa 500 ℃, mme e ntse e na le thata e phahameng ho 1000 ℃.
Li-tungsten sel, eo likarolo tsa sehlooho tsa eona li tung le coult, li-account tsa likarolo tsohle le cartide, le tsona li nkoa e le meno a indasteri ea sejoale-joale.
Lehlaka le tšepe ke lisebelisoa tse mpe tse nang le sebopeho sa tšepe se le seng sa koloi ea tšepe. Tungns Carbide, Cobalt Carbide, Cobalt Carbide, Tinabium Carbide, 'me koloi ea tantum ke likarolo tse tloaelehileng tsa tšepe. Boholo ba lijo tsa lijo-thollo tsa carbide (kapa karolo) hangata ke maemong a 0,2-10, 'me lijo-thollo tsa carbide li tlama hammoho u sebelisa mojaro oa tšepe. Ka kakaretso metomo ea ho hlapela ka kakaretso tšepe tsa sehlopha sa tšepe, cobalt le nickel. Ka hona ho na le tukten-collt slloys, tukkel alloys le tukkel alloys le tukten-titanium-colbatt alloys.
Tungsntern Exerman ke ho tobetsa phofo ea sejong, ka nako eo ho e futhumatsa ka mocheso o itseng (mocheso o itseng ebe o e pholletsa pele ho fumana tšepe ea tungsten thepa e nang le thepa e hlokahalang.
①tungsten le Cobalt Centide Centide
Motsoako o ka sehloohong ke TUNGSTTER CARBIID (WC) le Binder Cobalt (CO). Mohato o entsoe ka "YG" ("Ho thata, cobalt" Hanyu Pinyin) le liperesente tse tloaelehileng dikahare tse tloaelehileng. Mohlala, YG8, ho bolelang karolelano ea WCO = 8% le tse ling kaofela ke koluoa ea carbide e halikiloeng.
