Balaadhinta Hoose ee Alloy Kovar 4j29 Wire, 29HK silig loogu talagalay xidhidhiyaha dhalooyinka Sawirka

Balaadhinta Hoose ee Alloy Kovar 4j29 Wire, 29HK silig loogu talagalay daawaha xidhida dhalada

Sharaxaad Gaaban:

Alloy-4J29 (Alaab balaarineed)
(Magaca guud: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 sidoo kale loo yaqaan Kovar alloy.waxa la alifay si loo daboolo baahida shaabad quraarad ilaa bir ah oo la isku halayn karo, kaas oo looga baahan yahay aaladaha elektiroonigga ah sida nalalka iftiinka, tuubooyinka vacuum, tubes cathode ray, iyo nidaamyada vacuum ee kimisteriga iyo cilmi baarista kale ee sayniska.Biraha badankoodu kuma xidhi karaan dhalada sababtoo ah isku xidhkooda balaadhinta kulaylku maaha mid la mid ah muraayadda, sidaa darteed sida wadajirka ah u qaboojiso ka dib abuurista culeysyada sababtoo ah heerarka kala duwan ee ballaarinta dhalada iyo birta ayaa keena wadajirka inay dillaacaan.

Alloy-4J29 ma aha oo kaliya balaadhinta kulaylka oo la mid ah muraayadda, laakiin qalooca fidinta kulaylka aan tooska ahayn ayaa badanaa la samayn karaa si ay ugu dhigmaan muraayadda, taas oo u oggolaanaysa wadajirku inay u dulqaadan karaan heerkul ballaaran.Kiimiko ahaan, waxay ku xidhaa galaas iyada oo loo marayo lakabka oksaydhka dhexe ee nikkel oxide iyo kobalt oxide;saamiga birta oksaydhku waa yar yahay sababtoo ah hoos u dhigida kobalt.Xoogga dammaanadda waxay aad ugu tiirsan tahay dhumucda lakabka oksaydhka iyo dabeecadda.Joogitaanka kobaltku wuxuu ka dhigayaa lakabka oksaydhku inuu si fudud u dhalaali karo oo ku milmi karo muraayadda dhalaalaysa.Midabka cawl, cawl-buluug ama cawl-brown ayaa tilmaamaya shaabad wanaagsan.Midabka macdanku waxa uu tilmaamayaa oksaydh la'aan, halka midabka madaw uu tilmaamayo birta oksaydhaysan ee xad dhaafka ah, labada xaaladoodba waxa ay keenayaan kalagoys daciif ah.

Codsiga:Inta badan loo isticmaalo qaybaha faakuumka korontada iyo xakamaynta qiiqa, tuubada shoogga, tuubada shidda, magnetron galaas, transistor-ka, fur shaabadda, gudbinta, rasaasta wareegyada isku dhafan, chassis, brackets iyo xidhidhiyeyaasha kale ee guryaha.
