A Study on the Porous Microstructure of Yakbone Bioceramic
Research on microstructure and behavior of natural biomaterials contributes to understanding the biomimetic design.Yakbone bioceramics cross section with innumerable voids was observed via SEM approach,then a digital image processing technique was adopted to analyze the images.It is supposed that the pores can be classified into n series by different size level.A non-linear function between the pore size and series number got fitted which indicates a regression trend to zero as n rising to a large number.A non-linear convergent analysis of the function results in the porosity of porous microstructure ofyakbone bioceramic.Furthermore,a plane helices characterization model was assumed to descript the multilevel voids distribution,then a series of helices parameters were designed for bionic yakbone porous microstructure with porosity tolerance of 2.5%.This parameter description of yakbone,a porous bioceramic with high strength and light weight,contributes to further research on the relationships between mechanical property and microstructure.
