Influences of the current density on the performances of the chrome-plated layer in deterministic electroplating repair
Deterministic electroplating repair is a novel method for rapidly repairing the attrited parts.By the qualitative contrast and quantitative comparison,influences of the current density on performances of the chrome-plated layer were concluded in this study.The chrome-plated layers were fabricated under different current densities when the other parameters were kept constant.Hardnesses,thicknesses and components,surface morphologies and roughnesses,and wearability of the chrome-plated layers were detected by the Vickers hardness tester,scanning electron microscope/energy dispersive X-ray detector,digital microscope in the 3D imaging mode,and the ball-milling instrument with profilograph,respectively.In order to scientifically evaluate each factor,the experimental data was normalized.A comprehensive evaluation model was founded to quantitative analyse influence of the current density based on analytic hierarchy process method and the weighted evaluation method.The calculated comprehensive evaluation indexes corresponding to current density of 40 2Adm2,45 A/dm2,50 A/dm2,55 A/dm2,60 A/dm2,and 65 A/dm2 were 0.2246,0.4850,0.4799,0.4922,0.8672,and 0.1381,respectively.Experimental results indicate that final optimal option was 60 A/dm2,and the priority orders were 60 A/dm2,55 A/dm2,45 A/dm2,50 A/dm2,40 A/dm2,and 65 A/dm2.
