Abstract
In this work High Velocity Oxy-fuel (HVOF) thermal spray
techniques, spraying
process optimization, and characterization of coatings
are reviewed. Different variants of the
technology are described and the main differences in
spray conditions in terms of particle
kinetics and thermal energy are rationalized. Methods and
tools for controlling the spray
process are presented as well as their use in optimizing
the coating process. It will be shown
how the differences from the starting powder to the final
coating formation affect the
coating microstructure and performance. Typical
properties of HVOF sprayed coatings and
coating performance is described. Also development of
testing methods used for the
evaluation of coating properties and current status of
standardization is presented. Short
discussion of typical applications is done
