Abstract

The erosion mechanism of ceramics coatings in Arata Coating Test with Jet Particles (ACT-JP) process was investigated experimentally and theoretically based on a fatigue crack propagation model by utilizing the relation between the erosion rate and ACT-JP condition. As results, the erosion of ceramics coatings depends on the crack propagation due to repetitive impact of jet particles and the separation of flattened ceramics particles from coating along the interface between ceramics particles. The erosion rate of ceramics coatings depends on the bonding strength of ceramics coating. It is possible to evaluate the bonding strength of ceramics coatings by measuring the erosion rate in ACT-JP process.
