Daawaynta dhamaystirka dusha sare waxay samaynaysaa habka lakabka dusha sare ee dusha sare ee walxaha, kaas oo leh qalab farsamo, jireed iyo kiimiko oo kala duwan oo leh walxo substrate ah.Ujeedada daaweynta dusha sare waa in la buuxiyo caabbinta daxalka alaabta, xirashada caabbinta, qurxinta ama shuruudaha kale ee shaqada ee gaarka ah.
Iyadoo ku xiran isticmaalka, farsamada daaweynta dusha sare waxaa loo kala saari karaa qaybaha soo socda.
Habka Electrochemical
Habkani waa isticmaalka falcelinta electrode si ay u sameeyaan daahan in dusha workpiece.Hababka ugu muhiimsan waa:
(A) Korantada
In xal electrolyte ah, workpiece waa cathode ah, kaas oo samayn kara a film daahan on dusha hoos falgalka hadda dibadda, kaas oo loo yaqaan electroplating.
(B) Anodization
In xal electrolyte ah, workpiece waa anode ah, kaas oo samayn kara lakabka anodized on dusha sare hoos falgalka hadda dibadda, kaas oo loo yaqaan anodizing, sida aluminium aluminium anodizing.
Anodization ee birta waxaa lagu fulin karaa hababka kiimikaad ama korantada.Habka kiimikooyinka waxaa la geliyaa workpiece galay dareeraha anodized ah, waxay samayn doontaa filim anodized ah, sida daaweynta bluing steel.
Habka kiimikada
Habkani waxa la isticmaalayo isdhexgalka kiimikada iyada oo aan hadda si ay u sameeyaan filim daahan on dusha workpiece.Hababka ugu badan waa:
(A) daawaynta filim beddelka kiimikaad
In xal electrolyte ah, workpiece ee maqnaanshaha hadda dibadda, by xalka walxaha kiimikada iyo isdhexgalka workpiece si ay u sameeyaan daahan on habka ay dusha, loo yaqaan daaweynta film beddelka kiimikada.
Sababtoo ah isdhexgalka ka dhexeeya walxaha kiimikaad ee xal iyo workpiece aan hadda dibadda kaas oo samayn kara filim daahan on dusha workpiece ah, kaas oo loo yaqaan film beddelka kiimikada.Sida bluing, fosfatinta, basbaaska, daaweynta cusbada chromium iyo wixii la mid ah.
(B) Ku dhejinta koronto la'aanta
In xal electrolyte ay sabab u tahay yaraynta walxaha kiimikaad, walxaha qaar ka mid ah shubay on dusha workpiece ah si ay u sameeyaan habka daahan, kaas oo loo yaqaan dahaadhaynta electroless, sida plating electroless nickel, dahaarka naxaas electroless.
Habka habaynta kulaylka
Habkani waxa uu samaynta dhalaalidda walxaha ama fidinta kulaylka ee xaaladaha heerkulka sare si ay u sameeyaan filim daahan on dusha workpiece ah.Hababka ugu badan waa:
(A) Ku-meel-gaadhsiis kulul
Ku rid qaybo bir ah birta dhalaalaysa si ay u sameeyaan filimka daahan ee dusha sare ee workpiece, kaas oo loo yaqaan plating kulul, sida galvanizing kulul-muquufin, aluminium kulul iyo wixii la mid ah.
(B) Ku buufinta kulaylka
Habka atomizing iyo buufinta birta dhalaalaysa ee dusha sare ee workpiece si ay u sameeyaan filim daahan waxaa loo yaqaan buufinta kulaylka, sida ku buufinta kulaylka ee zinc, buufin kulaylka ee aluminium iyo wixii la mid ah.
(C) Shaabada kulul
The bireed The biraha kululeeyo, cadaadisay dabooli dusha workpiece si ay u sameeyaan habka film daahan, kaas oo loo yaqaan shaabadeynta kulul, sida bireed kulul iyo wixii la mid ah.
(D) Daaweynta kulaylka kiimikaad
Samaynta workpiece xiriir kiimikaad iyo ha xubno qaar ka mid ah galay dusha workpiece xaalad heerkulka sare, kaas oo loo yaqaan daaweynta kulaylka kiimikada, sida nitriding, carburizing iyo wixii la mid ah.
Hababka kale
Inta badan makaanik, kiimiko, kiimiko kiimiko, hab jidheed.Hababka ugu muhiimsan waa:
(A) Dahaarka rinjiyeynta (B) Duubista garaaca (C) dusha sare ee laysarka (D) Tignoolajiyada filimka aad u adag (E) Electrophoresis iyo buufin elektrostatic ah
