| Abstract: |
| With the development of material science and technology, the coating technology has been widely applied in many aspects. This article analyzed and studied the stress and strain fields of rolling contact for super hard-coating materials. According to the model of thrust ball bearing, the effect of material characteristics on the distribution of rolling contact stress field for super hard coating material was simulated by using numerical simulation method and ANSYS finite element software. The results showed that the maximum shear stress occured on the joint of coating and substrate. At the same time, the stress in substrate was much larger than that in the bulk material. |
