Fiilada Kovar 4j29 ee Fiilada Yar, 29HK ee loogu talagalay Daawaha Shaabadaynta Muraayadaha Sawirka La Soo Bandhigay

Fiilo Koronto oo Hoose ah oo loogu talagalay Daawaha Shaabadaynta Muraayadda Kovar 4j29, iyo Fiilo 29HK ah

Sharaxaad Gaaban:

Daawaha-4J29 (Daawaha Ballaarinta)
(Magaca guud: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 oo sidoo kale loo yaqaan Kovar alloy. Waxaa la hindisay si loo daboolo baahida loo qabo shaabad lagu kalsoonaan karo oo galaas-ilaa-birta ah, taas oo looga baahan yahay aaladaha elektaroonigga ah sida nalalka iftiinka, tuubooyinka faakuumka, tuubooyinka fakuumka ee katooliga, iyo nidaamyada faakuumka ee kiimikada iyo cilmi-baarista kale ee sayniska. Biraha badankood kuma xidhi karaan galaaska sababtoo ah isku-xidhkooda ballaarinta kulaylka lama mid aha galaaska, sidaa darteed marka kala-goysyadu qaboojiyaan ka dib sameynta cadaadiska ay sababaan heerarka kala duwan ee ballaarinta galaaska iyo birta waxay sababaan in kala-goysku uu dillaaco.

Calaamadaha Alaabta

Alloy-4J29 ma aha oo kaliya inuu leeyahay fiditaan kuleyl oo la mid ah galaaska, laakiin qalooca ballaarinta kulaylka aan tooska ahayn ayaa badanaa loo samayn karaa inuu la mid noqdo galaaska, taasoo u oggolaanaysa isku-xidhka inuu u dulqaato heerkul ballaaran. Kiimiko ahaan, waxay ku xidhmaysaa galaaska iyada oo loo marayo lakabka oksaydhka ee dhexdhexaadka ah ee nikkel oxide iyo cobalt oxide; saamiga oksaydhka birta ah waa hooseeyaa sababtoo ah hoos u dhaca uu la socdo kobalt. Xoogga isku xidhka ayaa aad ugu tiirsan dhumucda lakabka oksaydhka iyo dabeecadda. Joogitaanka kobalt wuxuu ka dhigayaa lakabka oksaydhka mid fudud in la dhalaaliyo oo lagu milmo galaaska dhalaalay. Midab cawlan, cawlan-buluug ama cawlan-bunni wuxuu muujinayaa shaabad wanaagsan. Midabka birta ah wuxuu tilmaamayaa la'aanta oksaydhka, halka midabka madow uu tilmaamayo biraha oksaydhka ah ee aadka u oksaydhka badan, labada xaaladoodba wuxuu horseedaa kala-goyn daciif ah.

Codsiga:Waxaa inta badan loo isticmaalaa qaybaha faakuumka korontada iyo xakamaynta qiiqa, tuubada shoogga, tuubada shidista, magnetron-ka galaaska, transistors-ka, fiilo shaabadaysan, relay, hogaamin wareegyo isku dhafan, shasis, biriishyo iyo shaabad kale oo guryaha lagu xidho.
