Influence of processing methods on number and form of cracks of bionic units on vermicular cast iron

摘要：

　　This paper focuses on the influence of processing methods on the cracks number and form of bionic units on the vermicular cast iron.The results show that there have already been cracks on the bionic units surface,and the crack number increases with the thermal cycles.The cracks form on bionic units processed in air is tree-like structure,and that of bionic units processed in water is network structure.The twice laser process and the electro-pulsing treatment can effectively reduce the crack number of the bionic units processed in water,without changing theform.
