buufin balaasmaha budada kobalt alloy
Sharaxaada Alaabta
Sifooyinka ugu fiican ee budada daawaha ee kobalt-ku salaysan waxaa sabab u ah ka kooban kiimiko gaar ah iyo qaab-dhismeed yar.Waxay ka samaysan tahay noocyo kala duwan oo bir ah oo isku dhafan oo isku dhafan iyada oo la raacayo qayb ka mid ah ka dib dhalaalidda heerkulka sare, taas oo nuxurka kobaltku uu sarreeyo, sidaas darteed waxay leedahay adkeysi wanaagsan iyo caabbinta daxalka.Isla mar ahaantaana, daawadu waxay sidoo kale ka kooban tahay qadar ku habboon oo bir ah, chromium iyo walxo kale, si ay si fiican u xirto caabbinta.Habka wax-soo-saarka, budada daawaha ee kobalt-ku-salaysan ayaa la soo saaraa iyadoo la adeegsanayo habka birta budada ah ee horumarsan.Marka hore, walxaha birta ah ayaa la isku daraa iyadoo loo eegayo qayb gaar ah, ka dibna iyada oo loo marayo dhalaalid heerkul sarreeya, qaboojin degdeg ah iyo tallaabooyin kale oo geeddi-socod ah, iyo ugu dambeyntii hel budada daawaha isku midka ah.Budadani waxay leedahay heerar sare oo dareere ah, buuxinta iyo sifaynta guryaha, waxaana lagu farsamayn karaa qaabab kala duwan oo isku dhafan oo qaybo ah.
