Corrosion wore away wheel (6)
I believe the answer is:
rotate
'wheel' is the definition.
(wheel can mean to rotate round)
'corrosion wore away' is the wordplay.
'corrosion' becomes 'rot' (I've seen this in other clues).
'wore away' becomes 'ate' (eat can mean to erode or wear away).
'rot'+'ate'='ROTATE'
(Other definitions for rotate that I've seen before include "Turn around on axis or central point" , "'Er, to a T? (anag)" , "Gyrate" , "Go round and round" , "Turn around an axle, swivel" .)
