SiC seal rings were textured with inclined ellipse micropores,and the wear behavior of graphite seal rings against SiC seal rings was investigated experimentally.The wear volume of graphite seal rings under dry sliding conditions and the temperature rise under oil lubrication were measured.Results show that the graphite seal rings against textured surfaces present severer wear compared to those against smooth surfaces under dry sliding conditions.Under oil lubrication conditions,the temperature rise of texture surfaces is higher than that of smooth surfaces at a relatively low speed,which shows the effect of increasing wear,while the temperature rise of texture surfaces is lower than that of smooth surfaces at a relatively high speed,which shows the effect of decreasing wear.Under dry sliding and oil lubrication conditions,the surface texture can reduce the cutting and ploughing from the wear debris,making the graphite rings surface more smooth.
