Contact fatigue failure modes of HVOF coatings

2002-8-1A liquid fuel HVOF (JP5000) system was used to deposit WC–12%Co coatings on the surface of 440-C steel rolling element cones This system was selected because of its higher particle velocities which are in the range 1005–1118 m s −1 and a more uniform distribution of particles within the spray stream resulting in better coating quality
