Inta lagu jiro isticmaalka, qaybaha birta waxay u nugul yihiin daxalka korantada iyo daxalka kiimikada sababtoo ah saameynta jawiga shaqada. Waa wax caadi ah in codsiyada warshadaha si loo hagaajiyo sifooyinka dusha of workpieces iyada oo loo marayo technology daaweynta dusha iyo kor u sifooyinka anti-daxalka workpieces. Arrinkani waxa uu soo bandhigayaa laba teknooloji oo dusha sare leh oo leh sifooyin-ka-hortagga daxalka oo aad u wanaagsan: Farsamada daaweynta dusha sare ee Dacromet

Tiknoolajiyada daaweynta dusha sare ee Dacromet waa tignoolajiyada daahan ka-hortagga daxalka, inta badan loo isticmaalo ilaalinta dusha sare ee alaabta birta ah. Waxay isticmaashaa habka dhejinta elektiroonigga ah si ay si siman u daboosho dusha birta leh lakabka dahaarka ah ee aan dabiiciga ahayn ee leh sifooyinka ka hortagga daxalka. Heerkulka sida caadiga ah waa ku dhawaad ​​300 ° C. Dahaarkani wuxuu inta badan ka kooban yahay ultrafine flaky zinc, aluminium iyo chromium, kaas oo si wax ku ool ah u wanaajin kara caabbinta daxalka ee alaabada birta ah waxayna dheerayn kartaa noloshooda adeeg. Habka Dacromet wuxuu samayn karaa lakabka filimka cufan ee 4 ~ 8 μm dusha sare ee shaqada. Sababo la xiriira lakabyada isku dhafan ee zinc flake iyo aluminium, waxay ka hortagtaa warbaahinta wasakhaysan sida biyaha iyo ogsijiinta inay la xiriiraan qaybaha birta. Isla mar ahaantaana, inta lagu jiro farsamaynta Dacromet , chromic acid waxay si kiimiko ah ula falgashaa zinc, budada aluminium iyo birta saldhigga ah si ay u sameeyaan filim passivation cufan, kaas oo leh caabbinta daxalka wanaagsan.

Guud ahaan, tignoolajiyada daawaynta dusha sare ee Dacromet waa habka daawaynta dusha birta ee caadiga ah. Tiknoolajiyada Dacromet waxaa inta badan loo adeegsadaa ilaalinta ka hortagga daxalka, gaar ahaan furayaasha iyo xirayaasha. Waxaa si weyn loo isticmaalaa si loo hagaajiyo adkaanta iyo adkeysiga alaabta birta ah. Abrasive iyo iska caabin daxalka. Qalabka shaqada ee leh shuruudaha adag iyo ka-hortagga daxalka, tignoolajiyada Crow ayaa aad loo dabaqi karo. Markaad dooranayso tignoolajiyada daaweynta dusha ku habboon, waxay u baahan tahay in la doorto iyadoo loo eegayo shuruudaha codsiga gaarka ah.
