The two kinds of hard coatings are modeled by both anisotropic materials and involving their piezoelectric or piezomagnetic effects.
In this paper, two typical hard coating material are studied, namely the piezoelectric material PZT-5A with piezoelectric effect and piezomagnetic materials CoFe2O4 with piezomagnetic effect (Hereinafter abbreviated as A and B).
Hard coating material parameters of the blade in the engineering are different, but these two materials have a certain comparability.
