Schematic Diagram of the Wire H.V.O.F. Spray Process

 

 

Wire HVOF spraying developed after year 2000 and its goal is to deposit molybdenum in a layer with low porosity and hardnesses over 60 HRC.

H.V.O.F.W. Thermal Spray

This process replaces successfully hard chroming. Moreover, it has the advantage of deposition of thick layers over 1mm thickness, having an adherence and hardness superior to chroming. It is not limited by the piece size. The disadvantage is a higher price than that of the electrochemical chroming.
It can obviously be deposited any alloy or pure metal which can exist as wire and has a melting point under 3000º C.
