There has been a lot of talk about ceramic coating the crowns of pistons to improve the insulating properties of the piston and keep the heat where it can do the most use inside the cylinder. The most commonly used ceramic as far as I am aware is aluminium oxide which is deposited on the suface and using heat is bonded to the surface. Recently I have seen some debate as to wheater these coatings are any good.

Other coatings are also available for the piston skirt which are widely accepted as being benificial by reducing friction but it is very difficult to get hard facts and numbers to substanciate the claims.

What are you guys thoughts on this?
