Fa'amatalaga:
Silicon Carbide o loʻo i ai le meatotino o le sili ona lelei e faʻafefeteina, malosi faʻainisinia, maualuga le vevela, lubrication lelei e faʻaaogaina e pei o foliga faʻamaufaʻailoga, paʻu ma paipa i vaalele vaalele, masini, metallurgy, lomitusi ma vali, meaʻai, vailaʻau, fale gaosi oloa ma faapena. luga. Pe a tuʻufaʻatasia foliga sic ma foliga graphite o le feteʻenaʻiga e sili ona laʻititi ma e mafai ona faia i faʻamaufaʻailoga faʻainisinia e mafai ona galue i manaʻoga sili ona maualuga.
Silicon Carbide Meatotino Autu:
-maualalo le density
- Maualuluga le vevela (latalata i le alumini)
-Tete'e te'i vevela lelei
-Suavai ma kesi faʻamaoniga
- maualuga refractoriness (e mafai ona faʻaaogaina i le 1450 ℃ i le ea ma le 1800 ℃ i le ea le mautonu)
-E le afaina i le pala ma aua le susu i le alumini faʻafefe poʻo le zinc faʻafefe
-Maaa maualuga
-Fa'asa'o maualalo maualalo
-Abrasion tetee
- Tete'e i mea fa'avae ma malosi
-E mafai ona fa'alelei
- Malosi faʻainisinia maualuga
Talosaga Silicon Carbide:
- Faʻamaufaʻailoga faʻainisinia, paʻu, paʻu tui, ma isi
-Taliuli sooga
- Semiconductor ma faʻapipiʻi
-Pads Pump vaega
-Vaega kemisi
-Fa'ata mo faiga fa'aleisa fale gaosimea.
- Reactors fa'aauau pea, fa'afesuia'i vevela, ma isi.
Fa'aaliga
Silicon carbide e faia i ni auala se lua:
1) Pressureless sintered silikon carbide
A maeʻa ona faʻapipiʻiina le mea faʻapipiʻi silicon carbide, o le ata tioata vaega i lalo ole 200X microscope opitika o loʻo faʻaalia ai o le tufatufaina ma le tele o tioata e tutusa, ma o le tioata tele e le sili atu i le 10μm.
2) Reaction sintered silikon carbide
Ina ua uma le tali sintered silicon carbide chemically togafitia le vaega mafolafola ma lamolemole o mea, le tioata
tufatufaina ma le lapopoa i lalo ole 200X optical microscope e toniga, ma o mea e maua fua ole silicon e le sili atu i le 12%.
