Al-SiC_p复合材料磨损表面分形维数的研究

Fractal dimension investigation on wear behaviour of Al-SiC_p composite

旨在通过对SiCP增强Al基复合材料磨损表面的分形研究,更深入研究亚微米SiCP增强Al基复合材料的摩擦磨损特性与分形维数的关系。按照结构函数法,用MATLAB软件进行编程,得到复合材料双对数坐标图。研究标明,亚微米SiCP增强Al基复合材料的具有分形特性,且其分形维数与材料的磨损量有关,随着磨损量的增加,分形维数亦趋于增大。

The purpose of this paper is to provide a deeper understanding of the wear behaviour of SiCp/Al composites through a detailed examination of the wear surface and the sub - surface regions. Such an examination indicates that fractal dimension of micrometer SiCp reinforced Al matrix composite is related to wear volumne. According to the Structure function method, we can program with Matlab to deduce the fractal structure curve. With the increase of SiCp wear volume ,the fractal dimension is growing bigger and bigger.
