Wear Behaviour of Thermal Spray Welded FeNi and CeO₂ Composite Coatings

Abstract:

FeNi alloy powders with and without 0.4 % CeO₂ were flame spray welded onto 1045 carbon steel substrate. Vickers microhardness profiles of the coatings were carried out. Sliding wear tests in dry conditions were carried out by means of weight-loss method for several applications in oil industries. For this purpose, Ni-based alloy and high chrome cast iron were used as compared materials. A scanning electron microscope(SEM) was used to analyze the wear phenomena of samples. The result showed that the hardness of the coatings can be improved by addition of 0. 4 % CeO₂, and the anti-adhesion, anti-scratching, and plastic deformation resistance abilities of coatings are increased with the addition of CeO₂.
