Inert roj (AR, n₂), txo cov roj (h₂), lossis nqus plua plav ib puag ncig los tiv thaiv cov khoom siv oxidation lossis txhawb nqa cov kev cuam tshuam tshwj xeeb.
Nruab nrog lub ntsuas dej ntws nrog, roj purification, thiab siab tswj hwm vality, cov cua huv siab dawb huv thiab lub siab yog qhov tswj tau zoo.
5. Kas Taws Kub Nias Sintering Rauv Lub Cub Vauv Lub Tshuab Nqus Tsev
Ib lub twj siv tshuab thiab cov roj molecular tso kua mis ua ke ua ke ua ke ua ke ua ke (10⁻³ mus rau 10⁻⁵ PA) rau kev tshem tawm impurities lossis ua haujlwm nqus lus sintering.
6. KUB TSO KUA MINICT SINTTERING Rauv Txias Zog
Ib qho khoom siv dej txias lossis cov roj sai sai ua tiv thaiv cov khoom vim yog cua txias kom txias thiab nce ntxiv.
7. Kev Hloov Kub nias Sintering rauv taws cua sov thiab tswj siab tswj siab
Thermocouples (xws li w - dua thermocotre saib cov cua sov (0.1-30℃/ min).
Lub siab tswv yim system ua rau cov txheej txheem kev lag luam ruaj khov.
8. Kooj Kub Nias Sintering Rauv Kev Tiv Thaiv Kev Tiv Thaiv Kev Nyab Xeeb
Tsis siv neeg lub hwj chim thiab lub zog kub - tawm kev tiv thaiv rau kev txhoj puab, kub ntxhov, thiab dej txias.
Ii. Cua kub nias SINTERING FUAB NTA
1. Synergistic nyhuv ntawm cov kub kub thiab kub siab
Ib txhij ua tiav thov kub (1000-2500 degree) thiab kev kub siab (10.
2. Chaw Pom Txuj Ci
Inert atmospheres tiv thaiv cov ntaub ntawv oxidizable yooj yim (xws li Ti alloys); Txo cov cua nab kuab tshem oxide impurities (xws li h₂ thaum sintering wc - co); thiab lub tshuab nqus tsev yuav haum rau cov ntaub ntawv reactive (xws li sic).
3. Microstructure kev tswj
Los ntawm kho qhov kub thiab txias - kev nkhaus nyem, tso cai ntau lawm kev loj hlob, pub cov khoom siv nplua lossis cov khoom siv nanostructured.
4. Txuag Densification
Piv rau cov cua tshuab siab sintering, kub nias sintering tuaj yeem sheeth lub sijhawm Sintering (los ntawm ob peb teev mus rau kaum teev) thiab txo kev siv hluav taws xob.
5. Cov Duab Ua Raws Li
Ua ke nrog pwm tsim, ze - net {{}}}} duab qhov chaw tuaj yeem yog tus nqi txuas ntxiv, txo cov nqi tom ntej.
III. Kev Siv Cov Khoom Siv Cov Cua Kub Nias Furnaces
1. Huab cua Kub Nias Furnaces rau Ceramics
Cov Txheej Txheem Ceramics: Silicon Nitride (Si₃n₄) thiab Silicon Carbide (Sic) yog siv hauv cov cuab yeej thiab cov kabmob; alumina (al₂o₃) ceramic substrates.
2. Kev Ua Haujlwm Ceramics:
Piezoelectric ceramics (pzt), pob tshab ceramics (YAG).
