Abstract
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
