Alloy e Tlase ea Kovar 4j29 Wire, 29HK Wire for Glass Sealing Alloy

Tlhaloso e Khutšoanyane:

Alloy-4J29 (Katoloso ea motsoako)
(Lebitso le Tloaelehileng: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 e boetse e tsejoa e le motsoako oa Kovar. e ile ea qaptjoa ho finyella tlhokahalo ea tiiso e tšepahalang ea khalase ho ea ho tšepe, e hlokahalang lisebelisoa tsa elektronike tse kang libonela-monate, li-vacuum tubes, li-cathode ray tubes, le tsamaisong ea vacuum ea k'hemistri le lipatlisiso tse ling tsa saense. Litšepe tse ngata ha li khone ho tiisa khalase hobane coefficient ea tsona ea ho atolosa mocheso ha e tšoane le khalase, kahoo lenonyeletso le pholile ka mor'a ho etsa likhatello ka lebaka la litekanyetso tse fapaneng tsa ho atolosa ha khalase le tšepe li etsa hore lenonyeletso le phunye.

Alloy-4J29 ha e na feela katoloso ea mocheso e tšoanang le khalase, empa sekhahla sa eona sa ho atolosa mocheso se sa tloaelehang se ka etsoa hangata hore se lumellane le khalase, kahoo se lumella hore motsoako o mamelle mocheso o pharaletseng. Ka lik'hemik'hale, e tlamahane le khalase ka lera la oxide e bohareng ea nickel oxide le cobalt oxide; karolo ea tšepe ea oxide e tlase ka lebaka la ho fokotseha ha eona ka cobalt. Matla a tlamahano a itšetlehile haholo ka botenya ba oxide layer le sebopeho. Ho ba teng ha cobalt ho etsa hore oxide layer e be bonolo ho qhibiliha le ho qhibiliha ka khalase e qhibilihisitsoeng. Mmala o moputsoa, o moputsoa-putsoa kapa o mosootho o bonts'a tiiso e ntle. 'Mala oa tšepe o bontša ho haella ha oxide, ha 'mala o motšo o bontša tšepe e nang le oxidized ho feta tekano, maemong a mabeli a lebisang ho lenonyeletso le fokolang.
