Tribology of FeVCrC coatings deposited by HVOF and HVAF thermal spray processes

摘要

This work studies FeVCrC-based coatings as potential alternatives to conventional Ni-and Co-based alloys for wear protection. Specifically, the microstructure and tribological properties of the coatings are characterized as a function of the particle size distribution of the feedstock powder, of the deposition technique - High Velocity Oxygen-Fuel (HVOF) or High Velocity Air-Fuel (HVAF) spraying - and of specific processing parameters.
