【Abstract】 The microstructures of the surface of ZG45 treated by means of cast onsurface alloying processing with nickel base powder are investigated. The results show that, when the technological cast on surface alloying are designed availably, the nickel base powder can well be solved in the matrix material and the alloying layer would well bonded with the matrix material.更多还原
