The results show that the brush-plating coating is even and compact from section plane with good toughness and adhesion. The microhardness of the coating is 230.6HV0.5 which is 3 times of cast aluminium substrate. The wear resistance of the coating is 3 times of cast aluminium substrate. But the friction coefficient of the coating is 0.70 which is more high than that of the substrate, which is favorable for the fixed conjugate between the axis sheath and the axis seat of the gear-box.
