(Silicon Nitride PobTsim los ntawmWintrustek)

Silicon nitridenquag siv los ua ib feem tseem ceeb ntawm kev sib tsoo zeb rotors, sib tsoo xov xwm, thiab turbines. Cov khoom ua los ntawm silicon nitride muaj txog tib yam toughness lizirconiathaum piv rau cov khoom siv pa, tab sis lawv kuj muaj zog dua thiab hnav tsawg dua.

Si 3N4 sib tsoo pob's muaj zog thermal stability ua rau nws tsim nyog siv nyob rau hauv high-temperature thiab cryogenic sib tsoo txheej txheem. Lub pob qhov tshwj xeeb thermal kuj tso cai rau nws tiv taus qhov kub thiab txias hloov yam tsis tau poob nws txoj haujlwm lossis daim ntawv. Nws yog 60% sib zog dua cov hlau, nthuav tawm tsawg dua thermally, thiab muaj kev siv nyiaj qis dua tag nrho thaum piv rau lwm qhov sib tsoo nruab nrab. Vim nws qhov hardness zoo heev, nws tuaj yeem tiv taus qhov kev xav tau ntawm feem ntau hlau hmoov refining thiab crushing txheej txheem. Thaum siab hardness, tsawg kis kab mob, thiab tsawg abrasion xav tau, qhov no yog qhov zoo tshaj plaws sib tsoo nruab nrab.

Cov khoom

• Siab zog

• Zoo heev tiv taus hnav thiab corrosion

• Resilience rau qhov kub thiab txias

• Hluav taws xob rwb thaiv tsev

• Cov khoom tsis sib nqus

Lub ntsiab zoo ntawm silicon nitride tshaj steel pob:

1. Vim nws qhov hnyav 59% me dua li lub pob steel, nws txo qis dov, lub zog centrifugal, thiab kev sib tw hnav thaum cov kabmob khiav ntawm kev kub ceev;

2. Vim tias qhov elasticity modulus yog 44% ntau dua li cov hlau, qhov deformation yog qhov tsawg dua li ntawm lub pob steel;

3. HRC yog 78, thiab qhov hardness ntau dua li cov hlau;

4. Cov coefficient me me ntawm kev sib txhuam, hluav taws xob rwb thaiv tsev, tsis muaj hlau nplaum, thiab tiv taus tshuaj lom neeg ntau dua li cov hlau;

5. The material's coefficient of thermal expansion is 1/4 of that of steel, making it resistant to abrupt temperature changes;

6. RA tuaj yeem ncav cuag 4-6 nm, ua kom yooj yim kom ua tiav qhov tsis muaj qhov tsis zoo;

7. Muaj zog thermal kuj, ntawm 1050 ℃, silicon nitride ceramic pob tuav nws lub zog zoo heev thiab hardness;

8. Nws tuaj yeem ua haujlwm yam tsis muaj roj lubrication thiab tsis xeb.
