Titanium Dioxide - "Hartematal"

[PDVLanco]

I am searching for a process in the USA for coating aluminum analogous to a process available in Switzerland called "Hartematal". The process creates a very thin, very hard, and very wear resistant coating of titanium dioxide on the surface. A web search has only turned up a document from a German company who use the process for their solenoid valves. Any assistance is greatly appreciated!

KEPLA-COAT® for aluminium and titanium alloys, MAGOXID-COAT® for magnesium [probably the German company referred to]

Microplasmic Process (MPP) coats aluminum, magnesium, tantalum, titanium, zirconium and their alloys.
