 Combustion Spray Coarse 80/20 NiCr Powder |  Combustion Spray Fine 80/20 NiCr Powder |
 Plasma Spray Coarse 80/20 NiCr Powder |  Plasma Spray Fine 80/20 NiCr Powder |
Plasma sprayed coatings generally have finer, denser microstructures with less oxide inclusions than combustion powder (flame ) sprayed coatings. Plasma provides rapid heating, low particle flight time, more inert flame and higher velocity than combustion flame.
Generally, coarse powders produce a coarser and more open structured coatings with less oxidation than fine powders. This is mainly due to the differences in surface area of the powder particles exposed in the flame.
