GTV:

Flame spray technologies (FST):

They are similar quality of products in comparision with Oerlikon Metco
There is also company which coating equipment producers - Clerici engineering (we have some equipment form this company and its quality is like Oerlikon):http://www.clerici-engineering.ch/maschinenbau.php
If you cannot choose of those companies I can reccomend products of Oerlikon-Metco but it is more expensive than others
The Metallisation and Saint-Gobain is not leading manufacturer of plasma spray equipment
