cylinder liner Ni-P composite plating anti-corrosion cost
- 摘要:
- 在缸套表面进行镍磷复合镀强化处理,可以提高湿式内燃机缸套耐腐蚀性能,但会增加产品的成本。研究了在普通贝氏体气缸套材料基础上去掉贵重金属镍,调整其他成分比例,在确保材料性能不变的前提下,降低产品的成本。结果表明,配合表面强化处理,缸套硬度高、耐腐蚀强、生产成本低,并可以延长发动机寿命。
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.
