| 中文摘要: |
| 采用机械镀工艺,在Zn-3%Al镀层形层过程中添加0～ 5%的稀土盐,获得几种稀土含量不同的Zn-3%Al-RE合金镀层。利用电化学方法,以pH= 5和pH= 7的1 mol/ L NaCl溶液,0.5 mol/ L NaCl+ 0.5mol/ L Na2SO4溶液,0.5 mol/ L Na2SO4溶液为6种腐蚀介质,测定几种镀层在每种腐蚀介质中的电化学参数。结果表明:几种镀层的耐电化学腐蚀性能随着腐蚀介质中Cl-浓度的增大均有所降低;稀土加入量对镀层耐电化学腐蚀性能的影响不遵循线性关系,加入量为2%和5%时所得镀层的耐电化学腐蚀性能较好。 |
| 英文摘要: |
| Zn-3%Al-RE deposited coating was prepared with addition of 0～ 5% of one RE salt during the Zn-3% Al coating forming process by the process of mechanical zinc plating.And its electrochemical parameters were measured under six media corrosion mediums, 1mol/ L NaCl, 0.5 mol/ L NaCl+ 0.5 mol/ L Na2SO4and 0.5 mol/ L Na2SO4solutions whichis pH= 5 and pH= 7. The result shows that all the alloy coating's corrosion resistance reduces as Cl- concentration increases;and the relationship between the impact of addition rare earth and the electrochemical corrosion resistant of coating does not follow the linear,the coatings addition 2% and 5% rare earth have better corrosion resistance. |
