REVETOX: thermochemical coating , the original !

Revetox is a ceramic coating based on chromium oxyde, very dense, very hard, and insensitive to corrosion. It offers significant advantages when compared to ceramic coating obtained from thermal spray coating or massive ceramic.

It is deposited via air spray, or dipping, followed by a thermo-chemical process during which it acquires its extraordinary charactéristics.

First belonging to companies Ceraver, Leguellec and Wallcomonoy Technologies, it is now only proposed and applied by Mourot Industries.
