anodisation
|a-no-di-sa-tion|
/ˌænədaɪˈzeɪʃən/
forming an oxide layer by electrochemical treatment
Etymology
'anodisation' originates from Modern English, specifically from the verb 'anodize' combined with the noun-forming suffix '-ation', where 'anodize' derives from 'anode' + '-ize' and 'anode' originally meant 'upward way' in Greek.
'anode' comes from Greek 'anodos' (ἀνοδος), where 'ana-' meant 'up, upward' and 'hodos' meant 'way, path'; it entered scientific English in the 19th century as 'anode', then formed the verb 'anodize' (US) / 'anodise' (UK), and later the noun 'anodization' / 'anodisation'.
Initially 'anodos' meant 'upward way' in Greek; over time the element 'anode' came to denote the electrode where current enters (the 'upward' or outgoing path in early electrochemical descriptions), and 'anodisation' evolved to mean the process of producing an oxide layer at that electrode.
Meanings by Part of Speech
Noun 1
the electrochemical process of creating a protective or decorative oxide layer on the surface of a metal (especially aluminium) by making it the anode in an electrolytic cell.
The anodisation of the aluminium parts increased their corrosion resistance and improved paint adhesion.
