We researhed the initial wear property of surface-finishing that are influenced by surface-roughness and surface-finishing methods.
Our wear testing machine is designed by Savin's weartesting machine type.
In the case of irregular wear is able to divide the first initial wear term and the second initial wear term. The roughness surface wear greater than the smooth surface when the surface are finished by same method but different finished surface are not.
We consider that the surfaces are found Beilby layer have greater wear-resistance than not found Beilby layer surface, but this consideration needs the more researches.
