| Abstract: | In order to solve the problem that the irregular pore structure of the surface of porous bioceramic coating prepared by laser cladding under a certain optimized optimal process parameters is difficult to describe with traditional Euler geometry. In this paper, the pore structure morphology of the bioceramic coating surface was tested by scanning electron microscopy (SEM) creatively, and the SEM image of the coating surface was processed to statistically analysis the pore structure parameters by the picture software Image J, and then the fractal dimension (Df) of the pore structure was tested by the classic area-perimeter (A-P) method, and the irregular pore structure was successfully systematically described. The research results show that the principle of the method is simple and operable, and the pore structure of the coating in the range of 2.5-10wt.% can be described by the Df value, which is related to the size and the complexity of the pore structure of the bioceramic coating. Corresponding to the pore structure of the 2.5, 5, 7.5 and 10wt.% bioceramic coating respectively, the fractal dimensions is 1.344, 1.352, 1.394 and 1.34, respectively. In which, the Df value of the 7.5wt.% coating is the highest, it was suggested that pore structure of the coating with 7.5% pore additive addition also has the largest number of pores in the most complex pore structure. |
