1Cr13Al4 FeCrAl alloy Bright Flat Strip/Badweyn Strip loogu talagalay Isticmaalka Iska caabbinta

Alloys-ka Fecral iyo Nickel-chromium ayaa loo doortay inay noqdaan walxaha iska caabiya iska caabbinta ku dhex jirta sababtoo ah alloys-ka nickel-chromium waxay leeyihiin iska caabbinta korantada oo sareysa oo si weyn loogu isticmaalo iska caabbinta filimada khafiifka ah [1, 2]. Iska caabbinta xaashida filimka daawaha nickel-chrome oo ka kooban 20% chromium waxay noqon kartaa mid u sarreysa 2-3 kiilo ohms weli waxay ilaalin kartaa xasillooni wanaagsan. Isku-darka heerkulka 1 ee iska caabbinta (TCR) ee daawaha nickel-chrome ee badan waa qiyaastii 110 ppm/°C. Marka lagu daro xaddi yar oo silicon iyo aluminium ah oo leh nickel-chromium, xasilloonida heerkulka ayaa si dheeraad ah loo hagaajiyaa.

Codsiga:
Iska caabbinta ku dhex jirta loox fiilooyin daabacan ayaa noqon doonta mid awood u leh yaraynta xirmooyinka oo leh isku halayn sare iyo waxqabad koronto oo la wanaajiyey. Ku-darka shaqada iska caabbinta ee substrate-ka laminate-ka waxay xoraynaysaa aagga dusha sare ee PWB ee ay isticmaalaan qaybaha kala duwan, taasoo suurtogalinaysa kordhinta shaqada qalabka iyadoo la dhigayo qaybo firfircoon. Daloolada Nickel-chromium waxay leeyihiin iska caabbinta korantada oo sareysa, taas oo ka dhigaysa kuwo wax ku ool ah oo loo isticmaalo codsiyo kala duwan. Nickel iyo chromium waxaa lagu dahaadhay silicon iyo aluminium si loo hagaajiyo xasilloonida heerkulka loona yareeyo isku-dhafka kulaylka ee iska caabbinta. Lakab khafiif ah oo iska caabbinta filimka ku salaysan daloolada nickel-chromium ayaa si joogto ah loogu dhejiyay duubabka bir-naxaas ah si loo abuuro agab loogu talagalay codsiyada iska caabbinta ee ku dhex jira. Lakabka iska caabbinta filimka khafiifka ah ee u dhexeeya naxaasta iyo laminate-ka ayaa si xulasho leh loogu dhejin karaa si loo sameeyo iska caabbinta kala duwan. Kiimikooyinka loogu talagalay xoqidda ayaa caan ku ah hababka wax soo saarka PWB. Iyadoo la xakameynayo dhumucda daloolada, qiimaha iska caabbinta xaashida laga bilaabo 25 ilaa 250 ohm/sq. ayaa la helaa. Warqaddani waxay isbarbar dhigi doontaa laba walxood oo nickel-chromium ah hababka ay wax ku qortaan, isku-midnimada, maaraynta awoodda, waxqabadka kulaylka, isku-dhejinta iyo xallinta wax ku qoridda.
