Electrodepunerea și galvanizarea sunt două metode de tratare electrochimică a suprafeței utilizate în mod obișnuit, and there are some differences in how they work:

Cum functioneaza:
Electrodepunerea: Electrodeposition is the process of forming a metal coating by reducing metal ions from the electrolyte solution and depositing them onto the surface of the workpiece. În electrodepunere, the plated workpiece acts as the cathode, connected to the negative electrode of the power supply, while the anode is the electrode in an electrolyte solution, usually of the same metal.

Galvanizarea: Electroplating is the process of depositing a metal coating on the surface of a workpiece to provide protection, decor, or other special properties. În galvanizare, the plated workpiece is usually the anode, connected to the positive terminal of the power supply, în timp ce catodul este sursa de ioni metalici, care poate fi un bloc metalic sau alți electrozi metalici în soluția de electrolit.

The working principle difference between electrodeposition and electroplating

Soluție electrolitică:
Electrodepunerea: Electrodeposition typically uses an electrolyte solution containing metal ions, care se reduc si se depun pe suprafata piesei de prelucrat in timpul electrolizei. The concentration and composition of metal ions in the electrolyte solution will affect the properties of the final deposited layer.

Galvanizarea: Electroplated electrolyte solutions usually contain gold-plated ions and other additives, precum inhibitorii, synergists, etc. These additives can adjust the properties and appearance of the coating and provide better coating quality.

The working principle difference between electrodeposition and electroplating

Application purpose:
Electrodepunerea: Electrodeposition is mainly used for the repair and modification of metal surfaces, which can repair the damaged metal surface through electrodeposition to improve its appearance and performance.

Galvanizarea: Galvanizarea este utilizată în principal pentru a oferi un strat protector, acoperire decorativă sau acoperire specială de performanță. Galvanizarea poate îmbunătăți rezistența la coroziune, rezistenta la uzura, electrical conductivity and other characteristics of the metal, and can change the appearance of the metal.

În general, electrodeposition and electroplating are both methods of using electric currents and metal ions in electrolyte solutions to form a metal coating on the surface of the workpiece, but they have some differences in working principle and application purposes. Electrodepunerea se concentrează mai mult pe reparații și modificări, în timp ce galvanizarea este mai axată pe asigurarea protecției și îmbunătățirea performanței.
