Abstract

Through the milling of nickel base superalloy, this paper studies the effect regularity of surface morphology on corrosion resistance of nickel base superalloy under the condition of different milling parameters. In order to be more intuitive to characterize the surface morphology, this paper defines Motif area ratio to characterize the surface topography. It is defined as the ratio of the surface area that can meet the threshold condition to the machined surface. Take surface roughness for an example to study the relationship between the surface roughness and the corrosion rate of workpiece. Experiment shows that the workpiece surface topography is the direct reason of the difference of corrosion resistance of workpiece material. The better surface morphology, the lower workpiece average corrosion rate and the worse surface morphology, the rapider average corrosion rate.
