Hi all

I just got my pistons back from a coating process using Keronite.

For all of you who want to know details of the benefits this brings, go to

Mine were done through Ramspott & Brandt who found a Keronite licensed coating shop here in Germany, able and willing to do small jobs at a

reasonable price.

Maybe this is not for everyone but at least I wanted to share the info with you.



Mind if I cut in ?

Keronite, also known as Micro-arc oxidation (MAO) or Plasma Electrolytic Oxidation (PEO) is a plasma-chemical and electrochemical process.  The process combines electrochemical oxidation with a high voltage spark treatment in an alkaline electrolyte, resulting in the formation of a physically protectiveoxide film on the metal surface to enhance wear and corrosion resistance as well as prolonging component lifetime. It is especially suitable for the surface oxidation and pigmentation of aluminum, titanium, niobium, zirconium, magnesium and their alloys. The treated components are used in buildings, mechanics, transportations and energy sectors. 

Plasma Electrolytic Oxidation—in Brief


 Is it good just for pistons? Can you coat the combustion chamber, too?
