Influence of Pores and Cracks Morphology on Mechanical Behavior of Thermally Sprayed Ceramics
Original language description
Pores and cracks have significant influence on the structural rigidity and mechanical behavior of the thermally sprayed materials. For some applications dense coatings are needed, while for others (e.g. thermal barriers) some level of porosity is desirable. Recent development in thermal spraying focuses on the tailored design of pores and cracks for specific applications. In this project, ceramic coatings with different level and morphology of pores and cracks were plasma and HVOF sprayed on titanium alloy substrates. Coating microstructures were observed using scanning electron microscopy. Mechanical behavior of the prepared coatings was evaluated using four-point bending test in terms of changing coating stiffness with increasing mechanical load bothin compression and tension. Significant level of coating nonlinearity and hysteresis were observed. Tests carried out for coatings with the same chemical composition but different microstructure proved strong dependency.
