Hnav tsis kam ntawm cov tshuaj tiv thaiv-sintered silicon carbide khoom

Cov yam ntxwv ntawm cov khoom

Silicon carbide crystal qauv:

Sib txawv silicon carbide siv lead ua qauv muaj qhov sib txawv hardness thiab lub zog. Piv txwv li, hexagonal -silicon carbide muaj hardness siab dua cubic -silicon carbide. Kev ncaj ncees thiab kev ruaj ntseg ntawm cov qauv siv lead ua kuj tseem cuam tshuam rau kev hnav tsis kam. Qhov ntau ua tiav cov qauv thiab qhov tsis xws luag tsawg dua cov silicon carbide siv lead ua muaj, qhov zoo dua nws hnav tsis kam.

Ceev:

Qhov siab dua qhov ntom ntawm cov khoom, qhov tsawg hauv qhov pores, qhov nruj ntawm cov khoom yog, thiab qhov tsawg dua nws yuav tsim cov kab nrib pleb thiab cov khoom tev tawm thaum kev sib txhuam, yog li qhia kev hnav zoo dua. Feem ntau hais lus, cov tshuaj tiv thaiv-sintered silicon carbide cov khoom lag luam nrog qhov ntom ntawm ntau dua 95% muaj kev hnav siab dua.

Kev npaj

Raw khoom zoo:

Lub purity thiab particle loj faib ntawm silicon carbide hmoov nyob rau hauv raw cov ntaub ntawv muaj ib tug tseem ceeb cuam tshuam rau hnav tsis kam. High-purity silicon carbide raw cov ntaub ntawv (cov ntsiab lus impurity tsawg dua 0.5%) tuaj yeem xyuas kom meej tias cov khoom muaj lub cev zoo thiab tshuaj lom neeg. Silicon carbide hmoov nrog finer particle loj thiab txawm tis (qhov nruab nrab particle loj li ntawm ob peb microns mus rau kaum ntawm microns) tuaj yeem tsim cov khoom denser thiab ntau yam khoom, yog li txhim kho hnav tsis kam.

Sintering txheej txheem parameter:

Optimization ntawm cov txheej txheem tsis xws li sintering kub, lub sij hawm thiab siab tuaj yeem txhim kho qhov zoo thiab hnav tsis kam ntawm cov khoom. Piv txwv li, los ntawm qhov tsim nyog nce qhov kub ntawm sintering (feem ntau nyob rau hauv thaj tsam ntawm 1500-1800 degree), ncua lub sij hawm sintering (nrog rau ob peb teev mus rau ntau tshaj kaum teev) thiab ua kom lub siab sintering (feem ntau ntawm {{1. }}MPa), silicon carbide hais tuaj yeem ua ke zoo dua, txo qhov tsis xws luag, txhim kho qhov ntom ntom thiab hnav tsis kam ntawm cov khoom.

Siv ib puag ncig

Kev sib txhuam tej yam kev mob:

Kev sib txhuam coefficient yog ib qho tseem ceeb uas cuam tshuam rau kev hnav tsis kam. Cov ntaub ntawv sib txhuam sib txawv thiab kev sib txhuam yuav ua rau muaj kev sib txhuam coefficient sib txawv. Nyob rau hauv ib cheeb tsam uas tsis muaj kev sib txhuam coefficient, hnav tus nqi ntawm cov tshuaj tiv thaiv-sintered silicon carbide cov khoom yog tsawg. Piv txwv li, piv nrog cov ntaub ntawv hlau, thaum silicon carbide thiab cov khoom siv ceramic tsim ib qho kev sib txhuam, qhov sib txhuam coefficient yuav qis dua thiab hnav me me.

Kub thiab nruab nrab:

Qhov kub thiab txias ib puag ncig yuav cuam tshuam rau cov khoom siv kho tshuab ntawm silicon carbide cov khoom, thiab tom qab ntawd cuam tshuam rau lawv cov hnav tsis kam. Nyob rau hauv ib qho kev ntsuas kub (xws li hauv qab 1000 degree), raws li qhov kub thiab txias, lub zog ntawm silicon carbide cov khoom yuav txo qis me ntsis, tab sis nws tseem tuaj yeem tswj tau zoo hnav tsis kam. Nyob rau hauv ib puag ncig nrog corrosive xov xwm, xws li kua qaub thiab alkali daws, silicon carbide cov khoom muaj kev ruaj ntseg tshuaj zoo, tab sis kev sib cuag mus ntev yuav ua rau cov tshuaj tiv thaiv rau ntawm qhov chaw, cuam tshuam rau nws qhov chaw zoo thiab hnav tsis kam.

Lub peev xwm ntawm cov tshuaj tiv thaiv-sintered silicon carbide cov khoom tseem tab tom tshawb nrhiav. Nws tsis yog tsuas yog cov khoom lag luam xwb, tab sis kuj tseem yog qhov tseem ceeb rau qhib qhov rooj rau yav tom ntej cov ntaub ntawv siv tau zoo.
