duudduuban Large galvanized silig galvanized habka formation lakabka

Habka samaynta lakabka galvanized dip kulul waa habka samaynta daawaha birta-zinc ee u dhexeeya matrix birta iyo ka baxsan lakabka zinc saafi ah.Dusha sare ee workpiece waxay samaysaa lakabka daawaha ee birta-zinc inta lagu jiro dhejinta kulul ee kulul, si birta iyo lakabka zinc ee saafiga ah si fiican loo isku daro.Geedi socodka ee silig galvanized duudduuban waaweyn si fudud lagu sifayn karaa sida: marka workpiece bir ah la quusiyo in xal zinc dhalaalaysa, zinc ugu horeysay iyo α-birta (jidhka-xaruneed) dhalaalid adag la sameeyey on interface ah.Kani waa kareem uu sameeyay birta matrixka ah ee lagu milmay atamka zinc ee xaalada adag.Labada atom ee birta ah ayaa isku xidhan, soo jiidashada cufisjiidad ee u dhaxaysa atamka waa mid yar.

Sidaa darteed, marka uu Zincku gaadho dhereg dhalaalka adag, labada walxood ee Zinc iyo atamka birta ah way isku fidsan yihiin midba midka kale, atamyada zinc-ka ayaa ku faafaya (ama dhex galay) matrixka birta ah waxay u guuraan shabagga tusmada oo si tartiib tartiib ah u sameysmaan. daawaha leh birta, halka ay birta ku firdhisay dareeraha zinc-ka dhalaaliyay waxay samaysaa isku-dhafan dhex-dhexaad ah FeZn13 oo leh zinc oo hoos ugu daadanaya gunta dheriga kulul ee galvanized, taas oo ah, zinc slag.Marka shaqada laga saaro xalka zinc leaching, dusha sare ee lakabka zinc saafiga ah ayaa la sameeyay, kaas oo ah crystals hexagonal, iyo maadada birta ee aan ka badnayn 0.003%.
Galvanizing Qulqulka Kulul, oo sidoo kale loo yaqaan galvanization-ku-kulul, waa hab lagu helo dabool bir ah iyadoo la dhex gelinayo xubin birta ah xal zinc la dhalaaliyay.Iyadoo horumarinta degdega ah ee gudbinta korantada sare, gaadiidka iyo isgaadhsiinta, shuruudaha ilaalinta ee qaybaha birta waxay noqonayaan mid sare oo sarreeya, iyo baahida loo qabo galvanizing-ku-kulul ayaa sidoo kale sii kordhaya.Sida caadiga ah dhumucda lakabka galvanized korontada waa 5 ~ 15μm, iyo lakabka weyn ee duudduuban galvanized silig guud ahaan waa in ka badan 35μm, xataa ilaa 200μm.Galvanizing-ku-kululku wuxuu leeyahay awood daboolan oo wanaagsan, daahan cufan oo aan lahayn wax ka mid ah organic.
