Effect of Surface Roughness on the Metal Surface Stress Layer
Abstract
this paper uses specimens of different surface roughness classes before and after compression cycle to make indentation hardness test delamination by spherical indenter, We get different influences and changes of surface roughness of the specimen surface in the same kind of processing methods. The results showed that with the increase in roughness class, level of deep processing and compression effects which affects deep layer will increase. After the material through a cycle compression, its surface will change accordingly elastoplastic, thus affects its stress layer.
