Investigation of stress field and wear depth of Cr-Mo-Cu alloy cast iron with nano-additives under abrasive wear

摘要：

　　The finite element method (FEM) was used to simulate the sliding wear progress.The stress field and strain field of Cr-Mo-Cu alloy cast iron with nano-additives under wear abrasion were analyzed through experiment and numerical investigation in this paper.And then the wear depth was got by calculation for different alloy cast irons by taking graphite morphology into account.The graphite morphology was changed by addition of nano-additives,with the aspect ratio of graphite was transformed from 2 to 10,three kinds of graphite aspect ratio prepared including 2,5 and 10.
