20. Electroplating

21. ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES
Electrolyte (n): A substance that, in solution or when molten, ionizes and conducts electricity.
CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

22. Plating with non-ferrous metals
A piece of zinc is also placed in electrolyte, and it is connected to the positive terminal (+) of the supply. This then becomes the anode (the positive side). An electric current then flows between the pieces of metal, through the electrolyte. This causes a chemical reaction, which deposits zinc on the cathode, plating the component.

23. ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES
Terminal (n): the mechanical device by which an electric connection to an apparatus is established the point where current enters or leaves any conducting component in an electric circuit
Collocation: Positive terminal (+) Negative terminal (-)

Anodize (v): to coat a metal especially magnesium or aluminum with a protective film by electrolytic means.
Word formation: Anodization (n)
CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

27. Plating with non-ferrous metals
A related process, called anodizing, is used to protect aluminium. The component to be anodized is connected to the positive terminal (to become the anode) and placed in an electrolyte, with a cathode. As electricity flows, aluminium oxide is deposited on the anode. As this is harder than aluminium metal, it provides protection.

28. ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES
Aluminium oxide (n): Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3.
