【摘要】：利用脈沖電鍍方法在Q235鋼表面制備N(xiāo)i-Cr-Mn合金鍍層。采用輝光放電光譜儀、電化學(xué)工作站等設(shè)備,研究了不同的配位劑:甲酸銨、檸檬酸銨、復(fù)合配位劑A對(duì)Ni-Cr-Mn合金鍍層成分、沉積速率及耐蝕性的影響。結(jié)果表明,三種不同的配位劑對(duì)Ni-Cr-Mn合金鍍層成分、沉積速率及耐蝕性的影響相同。隨著配位劑含量的增加,鍍層中Cr、Mn含量先升高后降低,Ni含量先降低后升高;然而沉積速率先升后降;復(fù)合配位劑A制備的Ni-Cr-Mn合金鍍層,具有最小的腐蝕電流密度、最大的腐蝕電位,分別為9.374×10~(-8)A/cm~2、-0.288 V,耐蝕性更佳。
[Abstract]:Ni-Cr-Mn alloy coating was prepared on the surface of Q235 steel by pulse electroplating. The effects of different coordination agents, such as ammonium formate, ammonium citrate and complex coordination agent A, on the composition, deposition rate and corrosion resistance of Ni-Cr-Mn alloy coating were studied by means of glow discharge spectrometer and electrochemical workstation. The results show that the effect of three different coordination agents on the composition, deposition rate and corrosion resistance of Ni-Cr-Mn alloy coating is the same. With the increase of the content of coordination agent, the content of Cr-Mn in the coating increased first, then decreased and then increased, but the deposition rate increased first and then decreased. The Ni-Cr-Mn alloy coating prepared by complex coordination agent A had the smallest corrosion current density. The maximum corrosion potential is 9.374 脳 10 ~ (-8) A / cm ~ (-2) -0.288 V, and the corrosion resistance is better.
