Carbide tungsten. The guryaha jireed, sumoobo, isticmaalka

carbide Tungsten (magac kale - monocarbide tungsten) - xarunta kiimikada ee tungsten, carbon, iyo dhoobada ah. walax tani waa mid ka mid ah ugu adag ee dhammaan dhoobada yaqaan la engegnaantiinna aawadeed u dhigma diamond: HRC waa ku dhawaad 90 cutub on Mohs Mohs meedka meesha sagaalaad. Muuqaal kale oo wanaagsan ee carbide tungsten waa iska caabin wanaagsan Duugga, heerkulka barafku sare iyo iska caabin aad u fiican in lagu qayilo. Qoraalkan waxaa haatan si weyn loo isticmaalaa in la abuuro core qalab goynta ah iyo qolofka hubka u dusaya.

guryaha jirka ah ee carbide tungsten

1. Xaaladaha caadiga ah, budada ah carbide tungsten granular waa isdiyaarintiisana ah macdan ah cawlan.

2. L. biyo.

4. Heerkulka barafku ee carbide tungsten waa 2870 degrees.

5. cufnaanta waa 15.8 g / santimetr³.

6. modulus The laastikada waa 450 ÷ 650 GPA

7. Saamaynta kulaylka loo siman yahay 8.4 +/- 0,2 kkalory / mol

8. Heerka entropy waa 8.5 +/- 1.5 calories / (bar per degree).

9. kulaylka The gaar ah heerkulka a siman yihiin in ay 293 darajo oo waa 8,53 calories / (bar per degree).

10. conductivity kulul Heerkulka of 25 darajo waa 0.07 Cal / (cm / s / ° C).

11. The Wehliyaha ballaarinta kaamerada waa 3,84 (3,9) * 106 1 deg.

12. resistivity The korontada heerkulka a of 200 degrees waa 19.2 +/- 0,3 microohm / cm.

13. conductivity The korontada gaarka ah waa 52200 Ohm-1 * cm-1.

Qaab dhismeedka carbide tungsten

The hadda loo yaqaan laba nooc oo WC - β-WC sare-cubic oo hexagonal α-WC.

Isticmaalka carbide tungsten

- farshaxanka ee soo saaridda qalabka taas oo waa in ay leeyihiin qalbi engegnaantooda aawadeed sare iyo iska-caabbinta daxalka wanaagsan;

- waayo shubid Duugga u adkaysta of qaybaha kala duwan in la qalo in ay xirtaan culus celceliska xamuulka lama filaan ah;

- si weyn loo isticmaalaa in soo saaridda ee qalabka kala duwan goynta, carbinta, giraangiraha shiidi doona, gelinno daloolin for qodista, axdi qarameedka iyo qalab kale goynta;

- kharashka tungsten ogolaanaya isticmaalka Alloys dhinacyo kala duwan (waxa ka kooban yahay Alloys adag, oo loo yaqaan magaca "Victory" iyo "Relit", oo ku saabsan 90%);

- loo isticmaalo ku xereen kaamerada iyo muuqashada foomka ah ee wax soo saarka budada blaastiigga abrasion u adkaysta ah;

- Waa mid ka mid ah qalabka loo isticmaalo in lagu bedelo hannaanka dahaadhay chromium electroplating olol-xawaaraha sare ah ku xereen;

- carbide hadda tungsten waa adag soo saaridda of projectiles iyo hub dusaya diirkja rasaas (si kastaba ha ahaatee, waxaa caadi u ah barakaca tartiib ah carbide tungsten du) ;

- in wax soo saarka ee kuul aalladda of 1 mm for qalimaan qad (nadiifinayo waxaa lagu qabtaa qalab gaar ah oo dhowr maalmood, iyadoo la isticmaalayo qadar yar oo ah koollada diamond);

- in soo saaridda ee loogu xarragoodo for Ilaalada aqoonyahanada dalka Swiss, dahabka - siddo, dugaagado, iyo murriyadihii, taas oo ay sabab u tahay iska caabin Duugga ah carbide tungsten ballan luster weligeed ah;

- isticmaalaa sida side for Hannaan platina ah;

- carbide tungsten adeegsaday in la abuuro shaabadood dhamaadka fallaadhihii farsamooyin qaar ka mid ah kiisaska deegaanka ayaa ku nafwaayay sare iyo / ama abrasiveness.

Tungsten carbide sumoobo

Qoraalkan waa kiimikaad inert. Sababtan darteed, in xaaladaha caadiga ah, waxa aanu khatar kasta oo halis ku ah dadka. Qiyaasta halis aan la qeexay labada aadanaha ama xoolaha. Studies in la soo qabtaa Technical dhaw iyo University of Leipzig, muujisay in lagu buufiyaa carbide tungsten geli karin galay noolaha. War sidee Qurub ganaax waa non-sun ah, laakiin marka la isku daro walxaha qaarkood ay khatar u ah ladnaanta unugyada. Marka deynta helo ciidda Cobalt iyo aan ku fekereyno maalka ah ee jirka ku horumarin karaan fibrosis.
