The unfolding wheel for testing steel ball is apt to wear. Manufacturing microstructure at its surface is a method to reduce wear. Firstly, friction and wear experiments were conducted with load and microstructure area as variables. The friction coefficients and wear mass of the specimens were measured. The friction and wear performance of the microstructure surface is studied by analyzing the data trend of friction coefficient and wear mass. Then, the mechanism on wear resistance of microstructure surface is analyzed. The mathematical model of wear is deduced based on the Archard wear model. The finite element simulations of wear of microstructure surface and smooth surface were conducted through ANSYS software respectively. Finally, the equation relationship between the unfolding wheel life and the number of wear is established by fitting the data from the simulation results using MATLAB. The predicted result shows that the unfolding wheel life of the microstructure surface is about 26.5 % longer than that of the smooth surface.
