(Ceramic to Metal Assmebled PartByakozwe naWintrustek)
I.Icyerekezo cya Ceramic-to-Metal Welded Component
Ceramic-to-metal welded ibiceni ibice byubaka byubaka bikoresha uburyo buhanitse bwo gusudira kugirango bitange imbaraga nyinshi, ubukana bwa gaze nyinshi, hamwe n’amashanyarazi yizewe / yumuriro hagati yibikoresho bya ceramic nicyuma. Bakunze gukoreshwa mubisabwa bikenera kwihanganira ubushyuhe bwinshi, imikazo, cyangwa ibihe bya vacuum.
II. Ikoranabuhanga rifatika
1. Amahame yingenzi ya tekiniki
Gukora ibyuma bifatika bifashisha ibintu bifatika (titanium, zirconium, hafnium, vanadium, nibindi) mukuzuza ibyuma kugirango bivemo imiti hamwe nubutaka, bikavamo urwego rwahujwe na chimique kuri ceramic-metal interface. Ibi bikoresho bikora bikurura ogisijeni, azote, na karubone. Gushyushya mu cyuho cyangwa mu kirere inert itera nanoscale reaction (urugero, TiO₂, TiN, TiC) hejuru yubutaka. Ibi bituma ushiramo icyuma cyuzuza icyuma, bikavamo kwizerwa "ceramic-reaction layer-braze gufatanya ibyuma".
2. Ibipimo byingenzi byingenzi
2.1 Brazing Yuzuza Ibyuma Sisitemu:
Ag-Cu-Ti: Inganda zisanzwe, imikorere myiza yuzuye
Cu-Ti: Igiciro gito, irwanya ubushyuhe bwinshi
Au-Ni-Ti: Kwizerwa cyane, gukoresha ikirere
Igicuruzwa kitagira ifeza: Kubikoresho bya elegitoronike bisaba gukumira kwimuka kwimuka
2.2 Kugenzura inzira:
Ibisabwa Ibidukikije: Icyuho kinini (
Igenzura ry'ubushyuhe: 20-50 ° C hejuru y'amazi yagurishijwe (800-900 ° C kuri sisitemu ya Ag-Cu-Ti)
Kugenzura Igihe: Iminota mike kugeza kuminota makumyabiri, kuringaniza reaction yuzuye hamwe nuburinganire bwimiterere
2.3 Inzira:
Mbere yo kuvura: Isuku ryuzuye ryubutaka no kuvura ibyuma; kuvanaho ibice bya oxyde mubice byicyuma
Inteko: Iteraniro ryiza ryibumba, ibikoresho byicyuma, hamwe na fayili yo kugurisha ikora (0.05-0.2 mm)
Vacuum Brazing: Kwimuka → Gushyushya gahunda → Gufata ubushyuhe → Kugenzura gukonje
Nyuma yo kuvurwa: Isuku nubugenzuzi bwibanze
III. Helium Mass Spectrometer Kumeneka Ikoranabuhanga
1. Gukenera Kumenya Kumeneka
Ibikoresho bya Ceramic-ibyuma bisudira bikoreshwa mubisabwa cyane nka sisitemu ya vacuum n'ibikoresho byo mu kirere. Menya neza ko byujuje hafi- "gufunga byimazeyo" ibipimo (igipimo cyo kumeneka
2. Ihame ryo gutahura
Ukoresheje helium nka gaze ya tracer, inzira ikoresha inyungu zayo ntoya, imiterere ya inert, hamwe nubushakashatsi bwibanze. Helium yinjira muri sprometrike ya misa ikoresheje kumeneka, ionisiyoneri, itandukanijwe numurima wa rukuruzi, kandi ikamenyekana na detector kabuhariwe. Imbaraga z'ikimenyetso zingana na helium, zemerera kubara neza igipimo cyo kubara.
3. Uburyo bukuru bwo gutahura
Uburyo 1: Uburyo bwo guhumura (Kumenyekanisha hafi)
Inzira:
Imbere yakazi yakuweho kandi ihujwe na disiketi yamenetse.
Agace ko gusudira hanze karasikanwa n'imbunda ya helium.
Ibimenyetso bikurikiranwa mugihe nyacyo kugirango tumenye neza ingingo zasohotse.
Ibiranga:Birakwiriye gushakisha ibimeneka mubice bito, sensibilité yo hejuru.
Uburyo bwa 2:Helium Hood / Uburyo bwo Gufunga (Muri rusange Isuzuma rya Kashe Yuzuye)
Inzira:
Igicapo cyuzuyemo helium hanyuma kigashyirwa imbere muri vacuum, cyangwa hood / sniffer yo hanze ikoreshwa mugutahura.
Helium yegeranye cyangwa ihunga iramenyekana.
Ibiranga:Ibipimo byose ligipimo cya eak; bikwiranye nibintu bigoye byubatswe.
4. Igikorwa cyo Gukora (Ukoresheje Uburyo bwo Guhumura nk'urugero)
4.1 Icyiciro cyo kwitegura:
Gukora isuku yakazi, kugenzura ibikoresho, no kwemeza ibidukikije bya helium.
4.2 Gushyira mu bikorwa Kumenya:
Igicapo cyahujwe na sisitemu yo gutahura kandi yimuwe ku gitutu cyo gukora.
Gutera Helium bitangira iyo umuvuduko wa sisitemu ugeze kuri .1 0.1 Pa (gutera imbunda intera: cm 1-2, umuvuduko: 0.1–0.2 MPa).
Gusikana kuri sisitemu hamwe no gusudira, hibandwa kubice byumuriro mwinshi.
4.3 Isesengura ryamakuru:
Impuruza iterwa niba igipimo cyo kumeneka kirenze igipimo (urugero, 1 × 10⁻⁹ Pa · m³ / s).
Ingingo zasohotse zashyizweho ikimenyetso, kandi imiterere yo kumenya hamwe namakuru byanditswe.
4.4 Kongera kugenzura no gutanga raporo:
Ongera ugerageze nyuma yo gusanwa, ukurikirwa no kubyara raporo yuzuye y'ibizamini.
5. Ibitekerezo bidasanzwe hamwe nubuziranenge
Ihinduka rya Ceramic-yihariye: Wibande ku kumenya uturere twa microcrack twatewe no kwaguka k'ubushyuhe budahuye.
Ibyiciro bya Sensitivity: Byatoranijwe hashingiwe kubisabwa; icyogajuru-icyiciro gisabwa gishobora kugera kurwego rukomeye nka 10⁻¹² Pa · m³ / s.
Kwubahiriza bisanzwe: Gukurikiza amahame yigihugu / igisirikare, ASTM, cyangwa inganda zihariye.
Isesengura ryananiwe: Isesengura rya Microstructural, nko gutandukanya ibyuma byerekana ibyuma no gusikana microscopi ya electron (SEM), kumanota yamenetse arenze ibipimo.
Wintrustek izakora ikizamini cya helium kuri buri ceramic kugeza ibice byicyuma. Nyamuneka reba hano hepfo kugirango werekane igipimo cyibipimo byacu:

IV. Ikoreshwa risanzwe
Ibikoresho bya elegitoroniki bipfunyika: Guhuza hagati yubutaka bwa ceramic (AlN / Al₂O₃) hamwe nu muringa mubice bya IGBT.
Ibikoresho bya Vacuum: Ceramic-to-metal kashe mubyihuta byihuta nibikoresho bya semiconductor.
Ikirere: Ibyuma bifata moteri hamwe nicyogajuru gifunga Windows.
Ingufu na Optoelectronics: Amavuta ya selile arahuza hamwe nububiko bukomeye bwa laser.
V. Incamake
Gukora ibyuma bifatika nuburyo bwibanze bwo gutanga umusaruroceramic-to-metalihuriro, hamwe na helium mass spectrometer yamenetse ikora nkibipimo bya zahabu yo kwemeza hermeticity. Guhuza ubwo buryo bwikoranabuhanga byombi byemeza igihe kirekire kwizerwa ryibikoresho byasuditswe mubihe bikomeye. Mubikorwa bifatika, nibyingenzi kunonosora ibipimo byerekana uburyo bwo guhitamo no guhitamo uburyo bukwiye bwo gutahura hamwe nurwego rwo kwiyumvisha ibintu bitewe n'imiterere y'ibikorwa, ibiranga ibintu, hamwe nibisabwa bikenewe. Ubu buryo butezimbere sisitemu yo gufunga ubuziranenge buva mubikorwa kugeza kugenzura.
