Vacuum feedthrough alumina Metallized Ceramic

  Phantsi kweemeko eziqhelekileyo, i-alumina ceramics inokumelana nobushushu obuphezulu, ukuxhathisa ukunxiba, ukumelana nokugqwala, ukomelela okuphezulu, ukuqina okuphezulu, ukugquma okulungileyo kunye nezinye iimpawu, kodwa ukusebenza kwayo, ukusebenza kwe-welding kumbi. Nangona kunjalo, izixhobo zetsimbi zineenzuzo zokuxhathisa ubushushu obuphezulu, ukumelana nokugqwala, amandla aphezulu, ukuhanjiswa kombane okuhle, kunye nokusebenza kakuhle komatshini kunye nokusebenza kwe-welding. Ngokwandiswa okuqhubekayo kwentsimi yesicelo se-ceramics yesakhiwo esiphezulu kunye nokuphuhliswa kweemfuno zobuchwepheshe obuphezulu, amaninzi amacandelo ahlala efuna iimpawu ezibanzi ze-ceramic kunye nezixhobo zetsimbi. I-Ceramic kunye nesinyithi inokudityaniswa ngokudibeneyo ngenkqubo yokutshiza i-ceramic metallized vacuum, kunye neendawo ezidibeneyo zesakhiwo kunye nezibonelelo zombini ze-ceramic kunye nesinyithi zinokufumaneka.

Ngenxa yokuba ubume bezinto ze-ceramic buhluke kwi-microstructure yezixhobo zetsimbi, i-filler metal kaninzi ayinakumanzisa i-ceramic surface, kwaye ayinako ukusebenza kuyo ukwenza ibhondi eqinile, ngoko ukutywinwa kwee-ceramics kunye nesinyithi yindlela ekhethekileyo yenkqubo. oko kukuthi, indlela ye-ceramic metallization: okokuqala ubambelele ngokuqinileyo kuluhlu lwefilimu yensimbi phezu kwendawo ye-ceramic efuna ukugqalwa, ukuze umphezulu ube neempawu zetsimbi. Emva koko qaphela ukubethelwa kwe-ceramic kunye nesinyithi. Emva kokwaziswa kolwazi olufanelekileyo, indlela ekhoyo ye-molybdenum kunye ne-manganese, indlela yegolide yokubeka, indlela yobhedu yobhedu, indlela yokubeka i-tin, indlela yokubeka i-nickel, indlela ye-LAP (i-laser metal plating) kunye nezinye iinkqubo ze-ceramic metallization.

I-vacuum brazing alumina metallized ceramic yinkqubo apho i-solder enendawo yokunyibilika ephantsi kunesiseko sesinyithi iyancibilika kwaye i-gap edibeneyo izaliswe yisenzo se-capillary ukufumana i-joint non-removable. Inkqubo yokutshiza i-vacuum ineenzuzo zokungabi nasidingo sokusebenzisa i-flux aid kunye nokuqina okulungileyo kwendawo yokutshisa ngenxa ye-deoxidation. Kwiminyaka yakutshanje, kunye nophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe, iteknoloji yokuqhayisa ithatha indawo ebaluleke ngakumbi kumacandelo ahlukeneyo oshishino, ngokukodwa kwizixhobo zombane kunye nokhuselo lwesizwe kunye namanye amashishini iye yaba yindlela yenkqubo engenakubuyiselwa. Umzekelo, iijenereyitha ezinkulu zeoksijini, abatshintshi bobushushu abaneemilo ezintsonkothileyo (i-oyile epholileyo, i-evaporators kunye ne-radiator, njl.njl.) ezisetyenziswa kwiimoto kunye neenqanawa, izakhiwo ze-honeycomb ezinemilo enzima kwiinjini zejethi, iindawo zombane, iindawo zoomatshini ezichanekileyo, njl. brazed.

Kweli phepha, uluhlu lweemvavanyo zobuchwepheshe kunye nezicelo zemveliso ye-vacuum brazing zenziwe. Isitshixo sokuqhafaza sisithuba esifanelekileyo sokubambisana, ukhetho oluchanekileyo lweeparameters zenkqubo yokubhobhoza kunye nenkqubo yokugcoba i-vacuum.
