An absolute critical component to thermal spray systems is the powder feeder. The two common types used are the rotating disk and the fluidized bed powder feeders. I have been asked various times as to which one is the best.
Some of the more common fluidized bed powder feeders are the 4MP, 9MP, and the DJP.
The common rotating disk powder feeders are the
PF 700, the AT 1200. and the 1264,.
I have addressed this question in a short article on my web site. If you would like to read it, please click on:

At Thermal Spray Depot we are proud to be a distributor for the AT 400 twin wire electric arc spray system manufactured by Thermach. We have been asked if the AT 400 by Thermach is the same as the BP400 built by Praxair Tafa.
They are not the same, for a more detailed comparison, please click on this link:

Keep asking questions!

What is the best way to prepare the surface before thermal spray?
Grit blast is the best way to prepare a surface for thermal spray. This is after all oil and grease has been removed from the part to be sprayed. The purpose of grit blasting is to remove all oxides and foreign material from the surface being sprayed. More importantly, the grit blast operation results in a surface that has many pits and textured areas where the thermal spray can attache to and lock into. The most common material used for grit blast is aluminum oxide and chilled iron.
