Hardfacing technique

[gcb]

I would like to identify an alternative technique to electroplating for the application of a chromium carbide based hardfacing surface layer. Typically the layer would be 0.002" - 0.006" thick and should operate at temperatures of up to 700°C.

I would assume that PVD or micro-arc welding may be suitable tecniques, but if anyone can provide specific details regarding equipment and materials it would be very much appreciated.

Possibly Plasma Flame Spray.
