Metal dish gets coating (6,5)

I believe the answer is:

silver plate

'coating' is the definition.
(silver plate is a kind of coating)

'metal dish' is the wordplay.
'metal' becomes 'silver' (silver is a metallic element).
'dish' becomes 'plate' (plate is a kind of dish).
'silver'+'plate'='SILVER-PLATE'

'gets' acts as a link.

(Another definition for silver plate that I've seen is " Valuable metallic ware".)

I've seen this clue in The Mirror.
