Effect of the angle of incidence of abrasive particles on the erosive wear resistance of HVOF-sprayed composite coatings

The study presents test results concerning resistance to impingement erosion caused by solid particles transported in the gas stream. The angle at which the erosive jet affected the HVOF-sprayed coatings made using the Ni–WC flux-cored wire amounted to 30° and 90°. The study included microhardness measurements and the microscopic metallographic specimens of the deposited (sprayed) coatings.
Keywords: thermal spray, wire-high-velocity oxy-fuel (W-HVOF), erosion, flux cored wire
