Metallized Alumina Ceramics Rau Cov Khoom Siv Hluav Taws Xob
Hauv kev lag luam hluav taws xob hluav taws xob, lub tshuab nqus tsev physics, thiab kev sib txuas lus hauv aerospace, kev sib txuas lus zoo tshaj plaws ntawm insulating thiab withstand voltage zog ntawm ceramics nrog cov solderability ntawm hlau yog qhov tseem ceeb rau kev txiav txim siab lub kaw lus sealing kev ua tau zoo thiab lifespan. Peb Metallized Alumina Ceramics rau Cov Hluav Taws Xob Hluav Taws Xob siv cov txheej txheem moly-manganese lossis cov txheej txheem brazing kom loj hlob ib zaj duab xis hlau nyias nrog cov adhesion muaj zog heev ntawm cov nplais ceramic, muab kev txhawb nqa zoo rau kev sib txuas tom ntej.

Khoom Taw qhia
Metallized Alumina Ceramics rau Hluav Taws Xob Cheeb Tsam yog nyob rau hauv qeb ntawm precision functional ceramic cov ntaub ntawv, exhibiting heev complex lub cev zog:
Cov rwb thaiv tsev zoo heev ntawm cov ceramic matrix: Lub substrate yog ua los ntawm 95% -99.6% siab- purity alumina ceramic, muaj qhov ntim siab heev thiab lub zog dielectric, muaj peev xwm tiv taus qhov cuam tshuam ntawm ntau txhiab volts yam tsis muaj kev puas tsuaj.
Kev ua tau zoo ntawm txheej txheej metallization: Cov txheej txheej metallization txheej nthuav tawm cov ntawv tshwj xeeb tom qab sintering, thiab tom qab npib tsib xee plating, nws muaj cov brazing wettability zoo heev, ua rau siab - muaj zog sib txuas nrog cov hlau xws li tooj liab thiab Kovar alloys.
Dense microstructure: Under a microscope, a distinct "interdiffusion layer" is formed between the metallization layer and the ceramic matrix. Qhov no yog qhov tshwm sim ntawm kev sib tshuam ntawm cov hlau ions thiab ceramic nplej ntawm qhov kub thiab txias; qhov kev sib raug zoo ntawm lub cev no muaj zog dua li qhov kev sib txuas ntawm lub cev.
Herroneous yam ntxwv: Raws li lub plhaub los yog insulating lub hauv paus rau lub tshuab nqus tsev twj, cov khoom muaj kev ua tau zoo heev herroneous (feem ntau nrog ib tug leakage tus nqi qis dua 10^-9 Pa·m³ / s), zoo cais tawm sab nraud ib puag ncig thiab tiv thaiv rhiab hauv cov khoom.
Metallization Technology Nta|Lub hauv paus ntawm Kev Sib Txuas Kev Ntseeg
Metallization yog cov thev naus laus zis tseem ceeb ntawm hom khoom no. Nws lub hom phiaj tsis yog tsuas yog txheej txheej, tab sis los tsim cov ceramic-hlau hloov interface muaj peev xwm ua haujlwm ntev -.
Peb cov khoom siv metallized ceramic muaj cov yam ntxwv hauv qab no:
Cov txheej hlau ua ib qho metallurgical-qib daim ntawv cog lus nrog cov ceramic substrate, tsis yog lub cev adhesion.
Cov cheeb tsam metallized muaj cov tuab tuab thiab cov ciam teb ntshiab, ua kom yooj yim rau tom qab soldering thiab encapsulation.
Nws txhawb ntau yam kev tshaj tawm - cov txheej txheem ua, xws li npib tsib xee plating thiab nyiaj plating.
Cov txheej hlau tseem nyob ruaj khov thaum lub sij hawm siab -kub soldering thiab thermal cycling, thiab tsis yooj yim oxidized los yog migrated.
