Warshadaha electroplating-ka, electroplating-ka awoodda garaaca wadnaha ayaa soo jiitay dareenka sababtoo ah waxqabadkiisa dahaarka ee heerka sare ah. Marka la barbardhigo electroplating-ka DC-ga dhaqameed, waxay heli kartaa dahaadh leh kiristaalo khafiif ah, isku mid ah, iyo nadiifnimo sare leh. Dabcan, electroplating-ka garaaca wadnaha kuma habboona dhammaan xaaladaha, waxay leedahay baaxad u gaar ah oo loo adeegsado.
Haddaba, waa maxay codsiyada ugu muhiimsan ee electroplating-ka garaaca wadnaha? Tani waxay ka bilaabataa dhowr faa'iido oo aad u wanaagsan.
1. Ka-dhigista dahaarka ayaa aad loo sii hagaajiyay
Inta lagu jiro gudbinta garaaca wadnaha, qulqulka ugu sarreeya wuxuu gaari karaa dhowr jeer ama xitaa in ka badan toban jeer qulqulka DC. Cufnaanta hadda oo sarreysa waxay horseedaa awood xad dhaaf ah, taasoo si weyn u kordhinaysa tirada atamka ku nuugaya dusha sare ee cathode. Heerka nucleation-ka ayaa aad uga dhakhso badan heerka koritaanka kiristaalka, taasoo keenta dahaar si fiican loo sameeyay. Noocan dahaarka ah wuxuu leeyahay cufnaan sare, adkaansho sare, daloolo yar, iyo iska caabin wanaagsan oo daxal ah, iska caabin xirasho, alxan, conductivity, iyo sifooyin kale. Sidaa darteed, electroplating-ka garaaca wadnaha waxaa si weyn loogu isticmaalaa goobaha electroplating-ka ee shaqeynaya kuwaas oo u baahan waxqabad sare.
2. Awood kala firdhis oo wanaagsan
Kala-soocidda garaaca wadnaha waxay leedahay awood kala-soocid wanaagsan, taas oo si gaar ah muhiim ugu ah qaar ka mid ah kala-soocidda qalabka korontada lagu shubo ee qurxinta. Tusaale ahaan, marka dahabka ama lacagta lagu dahaadho shaqooyinka waaweyn, kala-soocidda garaaca wadnaha waxay ka dhigi kartaa midabka mid isku mid ah iyo tayada mid deggan. Dhanka kale, sababtoo ah ku darista habka xakamaynta dibadda, ku tiirsanaanta tayada dahaarka ee xalka qubayska ayaa yaraata, xakamaynta hawlgalkana way fududahay. Sidaa darteed, qaar ka mid ah baahida sare ee kala-soocidda qalabka korontada lagu shubo, kala-soocidda garaaca wadnaha wali waxay leedahay qiimaheeda. Dabcan, kala-soocidda qalabka korontada lagu shubo ee ilaalinta caadiga ah, sida baaskiiladaha, qalabka lagu xidho, iwm., looma baahna in la isticmaalo.
3. Nadiifnimo sare oo dahaarka ah
Inta lagu jiro xilliga garaaca wadnaha oo aan la isticmaalin, waxaa jira habab wanaagsan oo lagu baabi'iyo dufanka oo ka dhaca dusha sare ee cathode-ka, sida gaaska haydarojiinta ee la nuugay ama wasakhda oo ka saarta oo ku soo noqota xalka, taasoo yaraynaysa isku-dhafka haydarojiinta iyo hagaajinta daahirnimada dahaarka. Nadiifnimada sare ee dahaarka waxay kor u qaadaysaa shaqadiisa. Tusaale ahaan, dahaarka qalinka ee garaaca wadnaha wuxuu si weyn u wanaajin karaa alxanka, socodka, iska caabbinta midabka, iyo sifooyinka kale, wuxuuna leeyahay qiimo muhiim ah oo ku saabsan militariga, elektarooniga, hawada sare, iyo meelaha kale.
4. Heerka kala-soocidda oo dhakhso badan
Dadka qaar ayaa laga yaabaa inay u maleeyaan in electroplating-ka garaaca wadnaha uu leeyahay heer kaydin oo ka hooseeya electroplating-ka hadda tooska ah sababtoo ah joogitaanka muddada daminta. Dhab ahaantii, sidaas maaha. Heerka fadhiisintu waxay ku xiran tahay wax soo saarka cufnaanta hadda iyo hufnaanta hadda. Marka la eego cufnaanta hadda ee celceliska ah, electroplating-ka garaaca wadnaha wuxuu u janjeeraa inuu si dhakhso ah u shubo sababtoo ah soo kabashada fiirsashada ion-ka ee gobolka cathode inta lagu jiro xilliga fasaxa, taasoo keentay hufnaan hadda oo sareysa. Sifadan waxaa loo isticmaali karaa wax soo saarka electroplating-ka ee joogtada ah ee u baahan dhigista degdega ah, sida fiilooyinka elektaroonigga ah.
Dabcan, marka laga soo tago codsiyada kor ku xusan, iyadoo la horumarinayo tignoolajiyada, sahayda korontada garaaca ayaa sidoo kale si joogto ah u ballaarinaysa codsiyadooda meelaha sida nanoelectrodeposition, anodizing, iyo soo kabashada elektrolytic. Elektroplating-ka caadiga ah, u beddelashada electroplating-ka garaaca si keliya si loo hagaajiyo hufnaanta wax soo saarka waxaa laga yaabaa inaysan dhaqaale ahaan dhaqaale ahayn.
