Conclusions
A single-component ceramic coating produced by plasma-spraying a powder mixture consisting of 85% of 5–30-μ particles and 15% of 70–110-μ particles exhibits improved thermal-cycling resistance, because the dispersed inclusions of the coarse fraction present in the coating hinder crack propagation and coating rupture. The chemical identity of the fine and coarse fractions has a beneficial effect on the properties of the coating.
