Numerical models of a textured surface under hydrodynamic and mixed lubrication conditions are established , respectively, based on the Reynolds equation and the P-C (Patir and Cheng) model. The models are solved via Matlab programming using the finite difference method combined with numerical iteration. The pressure distribution in the calculation domain and the theoretical friction coefficient of the textured surface are obtained, which are used as the criteria for judging the tribological properties of the textured surface. To explore the coating design parameters for improved wear resistance, an elliptical texture with different arrays and a circular texture with different coverage ratios are processed using a femtosecond laser on the surface of a zirconia-reinforced hydroxyapatite bioceramic coating. The friction and wear tests are conducted on a reciprocating test platform. The wear depth of the coating is characterized by a three-dimensional profiler, and the proposed numerical models are verified.
