ZrO2 Cov khoom muaj nqis Ceramic

Zirconia ceramic pob yog tiv taus qhov kub thiab kub thiab tuaj yeem ua haujlwm ruaj khov rau qhov kub thiab txias qis dua 1000 degrees Celsius nrog kev hloov me me. Nws muaj cov kev ua haujlwm thermal vibration zoo, thiab qhov ntsuas kub ntawm thermal vibration yog 200-260 degrees Celsius.

Cov teb thov: Feem ntau yog siv hauv kev sib tsoo ultrafine thiab kev tawg ntawm siab viscosity thiab siab hardness cov ntaub ntawv hauv qab ib puag ncig uas yuav tsum tau muaj menyuam tsis taus thiab xoom qias neeg;

Piv nrog steel pob, qhov zoo tseem ceeb ntawm cov pob txhaws yog:

(1) Nws yog 59% sib dua dua li cov pob steel, uas txo cov centrifugal quab yuam, yob thiab cov nyom ntawm txoj kev sib tw thaum cov kabmob khiav ntawm kev kub ceev;

(2) Cov qauv ntawm kev hloov pauv yog 44% loj dua li ntawm cov hlau, uas txhais tau hais tias tus nqi ntawm deformation yog me dua li ntawm cov hlau pob thaum raug quab yuam;

(3) Hardness siab dua li cov hlau, HRC ncav cuag 78;

(4) Cov coefficient ntawm kev sib txhuam yog qhov me me, tsis muaj hlau nplaum, tiv thaiv hluav taws xob, thiab ntau dua tshuaj tiv thaiv kev xeb ntau dua li hlau;

(5) Cov coefficient ntawm thermal nthuav yog 1/4 ntawm cov hlau, uas tuaj yeem tiv taus kev hloov kub sai;

(6) Lub npoo tiav zoo dua, Ra tuaj yeem ncav cuag 4-6 nanometers;

(7) Qhov kub tsis kam tiv taus, cov pob ceramic tseem muaj lub zog siab thiab tawv ntawm 1050 degrees Celsius;

(8) Nws yuav tsis xeb thiab tuaj yeem ua haujlwm nyob rau hauv cov roj-free lubrication tej yam kev mob.
