Fig. 6(a) and (b) display the SEM images of the HNBR surface under oil-based mud and water-based mud, respectively. As a good lubriing medium, the oil-based mud forms a lubriing film between rubber and metal surfaces to reduce direct contact of rubbing pair interface , . This may be the reason why the HNBR surface is relatively smooth and the friction coefficient is the …
