Tungsten khabhayithi. Iimpawu ezibonakalayo, zinetyhefu, ukusetyenziswa

Tungsten khabhayithi (elinye igama - Tungsten monocarbide) - ikhemikali ambaxa Tungsten, carbon, neeseramiki. Le into yenye kakhulu zonke iseramikhi owaziwa ngokuba lukhuni abamelwe diamond: HRC ngeenxa 90 iiyunithi kwi Mohs Mohs ithatha indawo yesithoba. Enye inkalo esihle carbide Tungsten na ukumelana elungileyo ukuguga, iqondo eliphezulu ukunyibilika kunye nokumelana ebalaseleyo igcwala. Le nto ke ngoku ngokubanzi kusetyenziswa ukwenza engundoqo ukusika isixhobo kunye namaqokobhe wezikrweqe lihlaba.

Iipropati Physical of Tungsten khabhayithi

1. Phantsi kweemeko eziqhelekileyo, a granular engumgubo Tungsten khabhayithi i ebuntsimbi Ndileka hina.

2. enyibilikayo emanzini.

3. Rockwell yobulukhuni nemivo ukusuka ku 87 ukuya 92.

4. lobushushu ukunyibilika Tungsten khabhayithi na izinyuko 2.870.

5. Le konga 15.8 g / santimetr³.

6. I modulus elastic ngu 450 ÷ 650 uTsvangirai

7. Isiphumo ubushushu elingana 8.4 +/- 0.2 kkalory / Mol

8. I-standard entropy ngu 8.5 +/- 1.5 calories / (adla isidanga ngalinye).

9. ubushushu ezithile kubushushu elingana degrees 293 yi 8,53 calories / (adla isidanga ngalinye).

10. conductivity Thermal kwiqondo lobushushu okukufutshane degrees 25 0,07 cal / (cm / s / ° C).

11. Ukwanda lomlingani thermal yi 3,84 (3,9) * 106 1 amaqo.

12. resistivity yombane kubushushu degrees 200 yi 19.2 +/- 0.3 microohm / cm.

13. I Unikezelo lombane lwe ethile yi 52200 Ohm-1 * cm-1.

Isakhiwo Tungsten khabhayithi

I kwaziwe iintlobo ezimbini WC - β-WC eliphezulu-cubic kunye ezinamacala α-WC.

Ukusebenzisa Tungsten khabhayithi

- kwimizobo ukulungiselela ukwenziwa kwezixhobo ekufuneka ngokuba lukhuni eliphezulu kunye nokumelana elungileyo;

- ukuguga-enganyangekiyo kukwazi of amalungu ahlukeneyo ukuba kusetyenziswe yokonakala enzima ku layisha umothuko avareji;

- ngokubanzi ezisetyenziswa xa kusenziwa izixhobo ezahlukeneyo ukusika, izilumkiso, amavili besila, drill amasuntswana ngenxa ukubhola, umama kunye nezinye izixhobo ukusika;

- iindleko Tungsten ivumela ukusetyenziswa aluminium kwiinkalo ezahlukeneyo (le nto ndiyibhalayo aluminium nzima, eyaziwa phantsi kwegama "Uloyiso" yaye "Relit", malunga-90%);

- esetyenziswa ukutshiza thermal kwaye livela ngohlobo ngumgubo eziphathekayo ukuze ukuvelisa Ipeyinti lingonakali-resistant;

- yenye izinto ezisetyenziswayo endaweni chromium inkqubo nesingxobo electroplating idangatye-high speed wokutshiza;

- khabhayithi Tungsten okwangoku esoyisayo ekwenziweni lwezinto nezikrweqe lihlaba iimbumbulu umphakathi (Noko ke, kukho isiqhelo sokuba ukubana okuthe Tungsten khabhayithi DU) ;

- ekuvelisweni amaso ultra-1 mm iintlanti yosiba (wokucoca lwenziwa kwi izixhobo ezikhethekileyo iintsuku eziliqela, usebenzisa encinci diamond paste);

- ekwenziweni nezacholo for imilindo elite Swiss, ubucwebe - nemisesane, izacholo kunye namacici, leyo ngenxa uxhathiso banxibe of Tungsten khabhayithi qinisekisa ayenechaphothi obungunaphakade;

- isetyenziswe njengendawo yenethiwekhi kuvala platinum;

- Tungsten khabhayithi mazisetyenziswe ekudaleni ekupheleni amatywina iintolo kwezinye iindlela kwiimeko apho okusingqongileyo kukho viscosity eliphezulu kunye / okanye abrasiveness.

Tungsten khabhayithi ubuthi

Le nto afana egalelwe. Ngenxa yesi sizathu, kwiimeko eziqhelekileyo, loo nto ayithethi kubangela nawo nawuphi na ingozi kubantu. Ithamo ebulalayo abakacaci mhlawumbi ngabantu okanye izilwanyana. Izifundo eziye zaqhutywa Dresden zobuGcisa University of Leipzig, wabonisa ukuba iinta- Tungsten khabhayithi kusichukumisa zibe eziphilayo. Enanikade amasuntswana emihle non-ezingenabungozi, kodwa xa zidibene zizinto ezithile bakha ingozi ngenxa ntle iiseli. Xa ityala ufumana ayibe uthuli kwaye ngokuqwalasela into umzimba ukuphuhlisa abanesigulo.
