Abstract：Ni-P composite plating on the surface of the cylinder liner can improve the corrosion resistance of the cylinder liner,but it increased the cost of the product.The precious metal nickel was removed from the common bainitic cylinder liner materials,and the proportion of other components was adjusted to reduce the cost of the product on the premise of keeping the materials properties unchanged.The results show that with the surface strengthening treatment,the cylinder liner has high hardness,strong corrosion resistance,low production cost,and can prolong the engine life.
