Ak'u inahanele u na le reng e ke keng ea hlola e ngwaswa 'me e tla lula e le ntle joalo ka letsatsi leo u sa tsoa e reka.
Tungsten e hloekileng ke tšepe e bosoasoi e matla e etsang karoloana e nyane ea lefatše (e ka bang 1/20 aunzi ka thane ea lejoe). Tungsten ha e hlahe e le tšepe e hloekileng ka tlhaho. Kamehla e kopantsoe joalo ka motsoako le likarolo tse ling. Ho hanyetsa ho hoholo le ho tšoarella ho etsa hore e be khetho e ntle bakeng sa mabenyane. Tshepe e entsoe ka binder e phahameng haholo ho hlahisa mabenyane a thata, a matla ebile a mengoapo.
Platinum, palladium kapa masale a khauta a na le bokhoni ba ho ngoapola, ho ikoba le ho koba habonolo. Lihele tsa Tungsten ha li kobehe 'me li tla lula li shebahala hantle joalo ka letsatsi leo u li rekileng ka lona pele. Tungsten ke tšepe e thata le e thata ho feta. U ka utloa boleng bo le boima bo boima ba tungsten. Ha o kopanya boima bo tiileng le polishe ea ka ho sa feleng ea tungsten hammoho lesale le le leng, o hlahisa letšoao le phethahetseng la lerato la hau le boitlamo.
Lintlha ka Tungsten:
Letšoao la Lik'hemik'hale: W
Nomoro ea Atomic: 74
Melting Point: 10,220 likhato tsa Fahrenheit (5,660 degrees Celsius)
Boikarabello: li-ounise tse 11.1 ka lisenthimithara tse 19.25 g / cm
Isotopes: Li-Isotopes tse hlano tsa Tlhaho (tse ka bang mashome a mabeli a motso o mong tsa isotopu tsa maiketsetso)
Lebitso Tšimoloho: Lentsoe "tungsten" le tsoa mantsoeng a Sweden a tung le sten, a bolelang "lejoe le boima"
Ts'ebetso ea Tlhahiso:
Phofo ea Tungsten e tletse ka masale a tiileng a tšepe ho sebelisa ts'ebetso e bitsoang sintering. Mochine oa khatiso o tiisa phofo ka har'a lesale e se na letho. Lesale le futhumetse ka seboping ka likhato tse 2 200 tsa Fahrenheit (1,200 degrees Celsius). Lihlopha tsa lenyalo tsa tungsten li ikemiselitse ho sintering. Tsamaiso e tobileng ea ho sintering e sebelisoa. Sena se kenyelletsa ho fetisa matla a motlakase ka kotloloho ka lesale le leng le le leng. Ha hona joale ho eketseha, lesale le futhumatsa ho fihla ho likhato tse 5,600 tsa Fahrenheit (3,100 likhato tsa Celsius), le ntse le nyamela lesale le tiileng ha phofo e kopana.
Joale lesale lea boptjoa ebile le bentšoa ka lisebelisoa tsa taemane. Bakeng sa mehele e nang le silevera, khauta, palladium, platinamo kapa li-inlay tsa gane, lisebelisoa tsa taemane li cheka kanale bohareng ba selikalikoe. Tshepe ea bohlokoa e manehiloe ka har'a lesale ka tlas'a khatello ebe e ntlafatsoa hape.
Tungsten Rings Vs Tungsten Carbide Rings?
Ho na le phapang e kholo lipakeng tsa reng ea tungsten le reng ea tungsten carbide. Tungsten ka sebopeho sa eona se tala ke tšepe e putsoa e brittle ebile e thata ho sebetsa le eona. Tshepe e putswa e thehiloe ka ho e sila hore e be phofo ebe e e kopanya le likarolo tsa khabone le tse ling. Tsena kaofela li petelitsoe hammoho ho theha carbide ea tungsten. Ke ka seoelo u tla fumana reng e hloekileng ea tungsten, empa e teng. Lihele tsa Tungsten carbide li matla ebile lia hanana ho feta lesale lefe kapa lefe.
E 'ngoe ea likarolo tse kholo ka ho fetisisa tsa tungsten carbide ring ke ho hanyetsa ha eona. Ho na le lintho tse fokolang feela polaneteng ena tse ka hohlang lesale la tungsten joalo ka daemane kapa ntho e thata e lekanang.
E 'ngoe le e' ngoe ea mehele ea rona ea tungsten e tla le waranti ea bophelo bohle. Haeba ho na le letho le ka etsahalang ka reng ea hau, re tsebise feela 'me re tla e hlokomela.
Na mehele ea hau ea tungsten e na le cobalt?
Che, ha ho joalo! Ho na le mehele e mengata ea tungsten carbide 'marakeng e nang le cobalt. Ha re na cobalt meheleng ea rona. Cobalt ke motsoako o theko e tlaase barekisi ba bang ba bangata ba o sebelisang ho hlahisa masale a tungsten. Cobalt kahare ho mehele ea bona e sebetsana le liphiri tsa tlhaho tsa 'mele' me e tla silafatsa, e fetole lesale la hao hore le be boputsoa bo lerootho ebe e siea letheba le sootho kapa le letala monoaneng oa hao. U ka qoba sena ka ho reka e 'ngoe masale a rona a tungsten carbide a se nang cobalt.
