Word formation: Galvanizing (n), galvanized (adj) e.g.: Galvanizing is applied with zinc to iron or steel in order to protect from corrosion. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES Molten (adj): being in a state of fusion especially when the liquid state is produced by a high degree of heat as molten iron. Synonyms: melted (adj), melting (adj) CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES Electroplate (v): To coat an object with a thin layer of metal using electrosis. Collocation: Electroplated objects (adj. phr.) Word formation: Electroplated (adj) CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

Electroplating

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

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.

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 (-) CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES Cathode (n): The electrode or terminal by which current leaves an electrolytic cell voltaic cell battery etc. e.g.: Cathode is the negative terminal electrode or element of an electron tube or electrolytic cell. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES Anode(n): The electrode or terminal by which current enters an electrolytic cell voltaic cell battery etc. e.g.: Anode is the positive terminal electrode or element of an electron tube or electrolytic cell CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

ÇANKAYA UNIVERSITY OFFICE OF BASIC & ELECTIVE COURSES 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

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.

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. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT
