摘要：
The problem of the unfolding wheel wear in the defect inspection process caused by the sliding friction from mirror ball slipping was solved by applying the patterns on the surface of the unfolding wheel to increase friction and reduce wear. The patterns with different characteristic parameters on the surface of the T10A specimen were processed by the laser micro-texturing technology. Single factor analysis method was used to test the point contact dry sliding friction on the MMW-1 vertical universal friction tester. Considering the comprehensive influence of both local laser hardening and geometrical parameters on the wear properties, the wear model of patterns based on the Archard theory and the test results was built. Finally, simulation technology and wear test were utilized to verify the wear model, thereby optimizing the characteristic parameters of the patterns. The results show that under the point contact dry sliding friction condition, three kinds of patterned surfaces increased friction and reduceds wear. The wear was accurately calculated using the wear model, and this is useful for determination of the wear properties under actual working conditions. The optimized diamond patterns with the pit area in the range of S2~S4 was selected. The proposed method provided the technical support for the defect inspection equipment of steel ball surface. Meanwhile, the proposed wear model provided a theoretical reference for the prediction of the patterned surface wear under dry friction condition. © 2017, Science Press. All right reserved.
