Stefan Ertler 1 Posted April 16, 2008 Report Share Posted April 16, 2008 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 http://www.keronite.com/motorsport.asp 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. Cheers Stefan Quote Mind if I cut in ? Link to post Share on other sites

MrDangerUS 129 Posted January 24, 2014 Report Share Posted January 24, 2014 (edited) 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 Plasma electrolytic oxidation can be used on all aluminum alloys. The coating’s properties and appearance depend on the alloy selected. The process forms an ultra-hard ceramic—from 800 HV to 2,000 HV (Vickers Hardness Test) depending on the alloy and the coating’s thickness. The atomic bond with the substrate provides the layer with adhesion values similar to the fracture strength of aluminum. A porous outer layer is suited to top coats or composite layers. The ceramic can withstand over 2,000 hours in salt fog when sealed—a key test for corrosion resistance. It can withstand temperatures of well over 900 degrees Fahrenheit continuously, and up to 3,500 degrees Fahrenheit for short periods. http://www.aluminum.org/Content/ContentGroups/Aluminum_Now_Magazine1/May_June_2006/Plasma_Electrolytic_Oxidation_Improves_Aluminum%C3%86s_Heat,_Wear_Resistance.htm Is it good just for pistons? Can you coat the combustion chamber, too? Edited January 24, 2014 by MrDangerUS Quote Link to post Share on other sites
