U Tseba Hokae ka Powder ea Tungsten Carbide?

Tungsten carbide e tsejoa e le e 'ngoe ea lisebelisoa tse thata ka ho fetisisa lefatšeng,' me batho ba tloaelane haholo le mofuta ona oa thepa. Empa ho thoe'ng ka tungsten carbide powder, thepa e tala ea lihlahisoa tsa tungsten carbide? Sehloohong sena, re tla tseba ho hong ka tungsten carbide phofo.

E le thepa e tala

Lihlahisoa tsa tungsten carbide kaofela li entsoe ka phofo ea tungsten carbide. Ha ho etsoa, ​​​​li-powders tse ling li tla ekeletsoa phofo ea tungsten carbide e le setlamo sa ho kopanya likaroloana tsa tungsten carbide ka thata haholo. Boemong bo botle, karolo e phahameng ea phofo ea tungsten carbide, e tla ntlafatsa ts'ebetso ea lihlahisoa tsa tungsten carbide. Empa ha e le hantle, tungsten carbide e hloekileng e senyeha habonolo. Ke ka lebaka leo binder e leng teng. Lebitso la mophato ka mehla le ka o bontsha palo ya ba tlamang. Joalo ka YG8, e leng sehlopha se tloaelehileng se sebelisoang ho hlahisa lihlahisoa tsa tungsten carbide, e na le 8% ea phofo ea cobalt. Tekanyo e itseng ea titanium, cobalt, kapa nickel e ka fetola ts'ebetso ea tungsten carbide. Nka cobalt e le mohlala, karolo e ntle ka ho fetisisa le e tloaelehileng ea cobalt ke 3% -25%. Haeba cobalt e feta 25%, tungsten carbide e tla ba bonolo ka lebaka la li-binders tse ngata. Tungsten carbide ena e ke ke ea sebelisoa ho etsa lisebelisoa tse ling. Haeba e ka tlase ho 3%, ho thata ho tlama likaroloana tsa tungsten carbide mme lihlahisoa tsa tungsten carbide ka mor'a hore li sintering li tla ba brittle haholo. Ba bang ba lona ba ka 'na ba ferekanngoa, ke hobane'ng ha bahlahisi ba re phofo ea tungsten carbide e nang le li-binders e hlahisoa ka lisebelisoa tse hloekileng tsa 100%? 100% lihlahisoa tse tala li bolela hore lisebelisoa tsa rona ha li sebelisoe hape ho tsoa ho ba bang.

Bo-rasaense ba bangata ba leka ho fumana mokhoa o betere oa tlhahiso ea ho fokotsa bongata ba cobalt, ha ba ntse ba boloka ts'ebetso e ntle ea tungsten carbide.

Mesebetsi ea tungsten carbide phofo

Tungsten carbide e na le litšobotsi tse ngata, kahoo ha ho thata ho nahana hore tungsten carbide phofo e boetse e na le melemo le litšobotsi tse ngata. Tungsten carbide phofo ha e qhibilihe, empa e qhibiliha ka aqua regia. Kahoo lihlahisoa tsa tungsten carbide li lula li tsitsitse lik'hemik'hale. Tungsten carbide phofo e na le ntlha e qhibilihang e ka bang 2800 ℃ le ntlha e belang e ka bang 6000 ℃. Kahoo cobalt e bonolo ho qhibiliha ha tungsten carbide phofo e ntse e le tlas'a mocheso o phahameng.

Haeba u thahasella lihlahisoa tsa tungsten carbide 'me u batla boitsebiso bo eketsehileng le lintlha tse ling, u ka RE THUTA ka mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
