Abstract The cylinder/valve plate friction pairs were proven to be subjected to wear and failure in axial piston pumps. The synergy method of surface micro-texturing and wet micro-blasting was put forward to enhance the tribological performance of H62 brass/38CrMoAl conjunctions. Tribological tests configured with disk-on-disk motions were performed to obtain the friction coefficient of flat, micro-textured, wet micro-blasted flat and wet micro-blasting micro-textured samples. The friction coefficient of wet micro-blasted flat samples was lower than that of merely flat specimens. The friction coefficient of wet micro-blasted flat and wet micro-blasting micro-textured samples was reduced with the increment of blasting time. The wear mechanisms of wet micro-blasted flat and wet micro-blasting micro-textured samples were distinct from that of flat and micro-textured samples.
