摘要

为了提升M142 铝合金材料表面的显微硬度、耐磨性和耐腐蚀性，采用田口方法设计L16正交实验来研究脉冲电化学沉积参数对Ni-Fe 镀层的力学性能、耐磨性能以及耐腐蚀性能的影响。基于方差分析研究脉冲参数电流密度、占空比和脉冲频率对镀层硬度、摩擦系数、磨损率、自腐蚀电流密度和电荷转移电阻性能的影响，最终通过灰色关联分析实现脉冲工艺的多目标优化。结果表明:脉冲参数中的占空比对Ni-Fe 镀层显微硬度的影响最为显著，而电流密度对镀层耐磨性能和耐腐蚀性能的影响较大。此外，使用灰色关联方法综合分析Ni-Fe 镀层的显微硬度、耐磨性以及耐腐蚀性这3 项性能，最终得出当脉冲参数频率为2 000 Hz、占空比为50%、电流密度为2 A/dm2时，Ni-Fe 镀层的综合性能最佳，具有最大显微硬度301.0 HV0.05和最大电荷转移电阻14 148 Ω·cm2以及最小摩擦系数1.06、最小磨损率51.45×10-4 mm3/(N·m)和最小自腐蚀电流密度0.57 μA/cm2。对比优化前后镀层的微观结构发现Ni-Fe 镀层晶粒的细化是性能再次提升的主要原因。

Abstract

In order to enhance the microhardness， wear resistance， and corrosion resistance of the M142 aluminum alloy material surface， the Taguchi method was employed to design L16 orthogonal experiments to study the effect of pulse electrochemical deposition parameters on the mechanical properties， wear resistance and corrosion resistance of Ni-Fe coatings.Based on variance analysis， the effects of pulse parameters such as current density， duty cycle and pulse frequency on the hardness， friction coefficient， wear rate， self-corrosion current density and charge transfer resistance of the coating were studied.Subsequently， the multi-objective optimization of pulse process was realized by grey correlation analysis.Results indicated that among the pulse parameters， the duty cycle had the most significant influence on the microhardness of the Ni-Fe coating， while the current density had greater impact on the wear resistance and corrosion resistance of the coating.Furthermore，by comprehensively analyzing the microhardness， wear resistance， and corrosion resistance of the Ni-Fe coating using the grey relational analysis method， it was finally concluded that when the pulse parameters were set as a frequency of 2 000 Hz， a duty cycle of 50%， and a current density of 2 A/dm2， the Ni-Fe coating exhibited the best comprehensive performance.The as-obtained coating had a maximum microhardness of 301 HV0.05，a maximum charge transfer resistance of 14 148 Ω·cm2， a minimum friction coefficient of 1.06， a minimum wear rate of 51.45×10-4 mm3/(N·m)， and a minimum self-corrosion current density of 0.57 μA/cm2.By comparing the microstructures of the coating before and after optimization，it was found that the refinement of the Ni-Fe coating grains was the main reason for the further improvement of the coating performance.
